• 'Power' and 'Exponential' trend lines does not

  I have a diagram of dispersion (pictured below) that I'm trying to find a best fit line for, but when I try to select either power or exponential disappears from the trendline, just like the R ^ 2 and equation. The amount of data in the cloud of points is very large; is there a reason that the numbers should not be able to calculate a power or an exponential trendline for this land? Thank you.

• 'several trend lines' numbers 3.0

  Years, I had an Excel spreadsheet that graphed the weekly course of actions as well as moving averages of 5 weeks, 15 weeks and 40 weeks.

  When I moved the worksheet to a number, I can get one of them, that I indicate in the Format Inspector (series-trendlines).  Interestingly, the bar under the graph shows three moving averages, but all with the same name.  All three titles are changing everything I put in the Inspector to Format.  But they all retain the colors I used in the Excel worksheet.

  You can recreate the data graphic that you have transferred to the numbers.  You don't mention what type of graph you have, but here's a quick 2D scatterplot I made, choosing to view the moving average.

  

  Note When you do then a 2D scatterplot, you do NOT want to be defined as a column header in the left column.

• Creation of period moving average trend line 50

  HI, im trying to set my curve in LabView and trying to create a 50 period moving average treadline as in excel.

  is it possible for me to do in LabView?

  I tried general polynomial Fit VI and a few other screw in unions, but failed to get anything close to the way I want

  any ideas? anyone?

  Charlie, there is a better VI called means"PtByPt". Look in the palette "Signal Processing > point-to-point > Prob and Stat > means. Add an advantage: this VI gives data valid for the first 50 points, although the average is not "development" or "stabilized" during early iterations. (Also, don't forget that primitives "delete table ' and 'Building the table' call memory, meaning Manager memory copies of great paintings and fast loop rates will result in a bottleneck of the CPU.) Using circular buffers is one way to alleviate this limitation.)

• Combination line point cloud, or disperse with trend marker

  Hi all

  I need a line and dispersion of APEX 4.2 combination...

  Looks like AnyChart can do it now...

  See:

  Scatterplot: combination of line and marker Charts & lt; / title & gt; & lt; link href = & quot;... /styles/Sample-Toolbar.CSS & quot;...

  And it seems that from the APEX 4.2 yet we cannot do this, if I saw the reference in this forum for a request for improvement for the next version (thank you Hilary)

  In the meantime, so I have something...

  The need is for a set of guidelines - a box has peaked, for example - to illustrate clearly the points in and out of the limits of quality.  In our case, the solid lines are constant for all parcels.  Dispersion points, and the series will change according to the data.

  In addition, the guide or trend lines are not horizontal or straight - they form a peak, as the roof of a House.

  I use trend lines, or I could use thresholds (backstory).  So far I do not see how to build a sharp trend line, or a threshold area has peaked.  Is it possible > I'm still looking.

  Suggestions?

  Thank you

  I figured out and just make a simple line - scatterplot.

  The trick is, start with the line chart, several series, and then change one or more of the series until the marker using the series Type selection list.

  When you start with a Scatter Plot, but this may be more close to what you want in the end, the series Type selection list isn't here.

  Reason: Request for a point cloud format is different - you can't dynamically change the type series unless the same query format applies.

• The XML of a trend is fully documented?

  Guys,

  I know the doc online that tries to explain the structure of the XML file that is used to add a trend, but I need an explanation best and most complete of the length and breath of what is possible. The document does not limit or available values. I need to understand the following:

  1. How many graphics can go on a page? The doc online is vague and has written 2 or 3, but what happens if I need more? Do I have to create new tests to allow most trends?
  2. How do we do more than a trend line appear in a unique xy chart? What are the permitted colours? (the doc lists as red).
  3. How treat the graphic process 7 days, months, etc.? Are what the data in files separated? Or the process selects just given to a larger interval (decimation of data)?
  4. Is it possible to change the color over time as a way to show if a limit is exceeded? Since color is sent with each data point, what happens when you change color over time?

  I have several older BB tests that I would like to add XML data, but the example given does not give me enough to go and it seems to be a proposal, all or nothing. I've experimented with code to try to reverse engineer how to send data from trend, but most of my tests don't produced no data on the BB perf directory server and no way to tell what I was doing wrong. I got a few trends for work by drawing traffic from BBNT, but this is NOT a good way to proceed and don't tell me that that I may or may not do.

  Any help would be appreciated. Doc

  PS - I posted a similar message at the end of one of the sons mentioned that I had participated who had the doc mentioned online. This message replaces this message.

  (1) I don't know what you're asking. Can you be more explicit?

  (2) colors are collected by the library. A new color is used for each trendline in a chart. The available colors are defined in skins/eng/amcharts_settings/settings.xml ( entries)

  (3) times are calculated on the fly. The software tries to create data points about 350 at the time. Graphic annual calculates about 1 day per data point. Monthly is about 2 hours of data points, etc...

  (4) for the time being the colors defined in the xml document are unused (AFAIK). They may be in the future.

  multiple trendlines, you can do the following (say % used by the player on a server, and there are 2 disks; C and D)

  4.60

  Put the hostname here

  Put a name of service here

  regardless of the color generated by your test for this host.service

  C

  color for this player

  % used

  75

  D

  color for this player

  % used

  60

  This should create the trend under bbvar/perf/hostname/service two files, C.%used and D.%used and when you view the log of the State host.service, and you, there should be a single graph with two Trendlines (a to C) and the other for D. Each player is set in a block. As far as I KNOW, there is no limit on the number of graphs, also, there is no limit on the trendlines on a single graph but if values differ too much (for example a line returns GB and all other return MB (a factor of 10)), you may not be able to properly view some trendlines.

• Any built-in support for cursors on the graph and trend curves

  Hello

  I went through the documentation to verify that no support exists to draw trend lines and using the slider on the axis (bargraph) but could not find anything related to it. Can you please confirm if there is any built-in support for cursors/trend lines in the component ojchart (bar graph) of the current version of JET.

  Thank you

  Subhash

  Hi Adoni,

  Due to the large number of possible algorithms, we do not provide built in calculation for trend lines. Our goal is rather to ensure that the user can display trend lines what they calculated, with the right amount of interactivity support. We have a very basic demo of this feature in the Cookbook: Oracle JET - graphics - Custom graphics: trendline. In this demonstration, we recommend using reference objects, rather than additional series, because the objects of reference do not allow a user to interact with the individual points or use features such as selection or drilling, which would be undesirable for a trend line.

  On the second question, could you give more details on this cursor you are referring? We have two ways to use our zoom and scroll feature:

  • Preview: Oracle JET - graph - Zoom & scroll: the time axis
  • Simple scrollbar: Oracle JET - graph - Zoom & scroll: categorical axis

  Thank you

• Lopez Burk field (Double reciprocal plot)

  Hi all

  I'm doing a double reciprocal plot of my data of the enzyme. I don't know how to go from a basic scatter chart plot to a double reciprocal plot.

  I got my macbook in 2014 and the software is: OS X 10.9.5 (13F1603)

  Thank you much in advance.

  Kind regards

  Hello j,

  Weber State University in Ogden, Utah, of a set of instruction has do a lot of Lopez Burk in MS Excel, that you can find here. Formulas to convert the data pairs are reversed, and the graph itself is a scatterplot with a linear trend line 'better to' added. Creating a table similar in number should be pretty simple by following the instructions in Excel.

• Adding trendlines in Excel chart

  I am trying to add a trendline to a chart in excel. Anyone have an example on how to do this? I use the excelreport.fp functions to open excel, data entry and make a table. How to use the functions of excel2000.fp to a trendline. I use CVI 8.1 and Excel 2007.

  ACowans,

  Your variables were fine, but there is a little more structure that must be put in place.  In Excel, when you define a trendline, you must select a series, so I started looking for methods that would take the graphic handle and return of the series.  From there on, I found that the trendline function must actually a handle to the collection of the trend series, so I had to find a method that returns the collection of trend lines as well.  Here is the code that I had to include to make a trendline:

  ExcelObj_Series seriesOne = 0;
  ExcelObj_Trendline trendHandle = 0;
  Trendlines CAObjHandle = 0;
  Info ERRORINFO.

  Excel_ChartSeriesCollection (chartHandle, & info, CA_VariantInt (1), & seriesOne);
  Excel_SeriesTrendlines (seriesOne, info, CA_DEFAULT_VAL, & trendlines);
  Excel_TrendlinesAdd (curves of trend, & info, ExcelConst_xlLinear, CA_DEFAULT_VAL, CA_DEFAULT_VAL, CA_DEFAULT_VAL, CA_DEFAULT_VAL, CA_DEFAULT_VAL,
  CA_DEFAULT_VAL, CA_DEFAULT_VAL, CA_DEFAULT_VAL, & trendHandle);

  The first method takes the graphic handle and returns the handle of the series (for series 1... change the CA_VariantInt setting (1) for the different series).  The second method takes the handle of the series, and the 3rd parameter (CA_DEFAULT_VAL) means that the function returns the collection of trendlines rather than a single trendline.  The collection of trend line is necessary for the following method.  The third method actually adds the trendline.

• Analysis of the order when there is a significant shift of DC signal

  Thanks for reading this. I use the Toolkit NI LabVIEW Order Analysis for direct analysis of signals of pledge of deformation of an attachment to a car engine. My goal is to acquire data of a part of the calibrated strain connected to an engine during the rampup and identify the controls in the signal of the strain. I am not able to understand a problem I see with my results in the power of order spectrum.

  I measure the signals of pledge of strain during the preparations for engine using the module 9235 cDAQ (1000 to 6000 RPM in 15 seconds). I also acquire the tachometer using the module NOR-9402 (counter). Then I converted the signals of the strain at the same angle signals and made the order power spectrum.

  Please order power spectrum resulting Fig1 shows. What I find that is the DC offset in the signal of strain presents itself as a high amplitude (red or green) peaks in the power spectrum of order (see Fig 1) around the order of 0. Because of these enormous peaks around order 0, the peaks of the order of a real interest around 2 or 3 command (blue or purple) are difficult to discern in the graph.

  The DC offset clearly shows the chart of strain vs RPM (RPM is a linear function of time), if necessary, it is identical to the strain vs time. The white line in figure 2 corresponds to the DC offset. In this example, the CC offset is constant during the rampup rpm, but more often, the party calibrated strain of experiences both change static and forced lengthening cyclic as in Fig. 3. Here the sudden part increases the deformation in traction, with cyclic constraint superimposed on top of that.

  My questions are:

  Am I missing a key here in preprocessing step?

  -I need a high pass filter to remove DC offset?

  Subtract the average value of the signal from the time signal based before sending to the treatment?

  How does a handle signals that have a variable static elongation a cyclical signal above the static signal? This appears to me a common scenario in the measures of constraint because ESA undergoes two different static and dynamic constraints in a motor boat.

  Thanks for your comments and advice!

  You have several choices, depending on what you want to do.

  If what you want is a nice parcel of land, and the DC signal not enough to affect your 1st order, then simply set the component continues to 0 once you analyze varies.

  Presto - instant removal of DC.  It is perfectly legitimate, as long as the domain controller is not wandering too.  Mathematically, it is exactly the same as the withdrawal DC before analyzing.  (an inverse THAT FFT of this result and you will get the signal without DC, if you don't believe me).

  OR

  You can do as Bob has suggested and take the average.  If your length of block is short compared with the rate of change of the real continuous component, it is fine.

  OR

  You can remove the trend by interpolation.  For example, for a block of 1024-pt, find the way to 100 points around (on each side of) the beginning of your block.  Find the way to 100 points around (on each side of) the end of your block.  Find an equation (Y = mX + B) to describe the trendline it and use this equation to subtract a different DC value for each point.

  OR

  You can remove the trend extrapolation and interpolation.  For example, for a residence of 1024 pt. find the average of the first 100 points and the last 100 points and assign these values X = 50 and X = 973 (1023-50).  Find an equation (Y = mX + B) to describe the trendline it and use this equation to subtract a different DC value for each point.  You need to face the fact that X = 0 starts BEFORE your trend line at X = 50, but that is basic algebra.

  Remove trendline technique is more accurate and necessary if the domain controller changes siugnificantly during your block.

• How to install 'R' with OBIEE 12 c

  Hello

  I know that R Oracle now comes embedded with the OBIEE server, so that you can do things like trend lines, etc. on the graphs. However, I do not think that it has in fact installed / configured by default. It is futile to attempt a search on 'R' in the installation documentation. Has anyone found the instructions on how to install R on 12 c OBIEE servers?

• Variable of the ampersand in table XML seems to have no effect.

  Hello

  I'm trying to implement a trendline in a chart. I am follwing the guideline in this discussion:https://community.oracle.com/thread/2170766.

  If I add a text determined in the XML as follows:

  < axis_markers >

  <>lines

  < line start_value = '2725' end_value = "2735" color = "Red" / >

  < / lines >

  < / axis_markers >

  It works very well. However, the trend line should in Dynamics, that's why I generate the code in a hidden field.

  When I speak in the hidden field by adding in the XML of the chart like that & P3_HIDDEN_ITEM the trend line is not displayed.

  Inspect the XML that I see the malformed XML error and I see as always ' & P3_HIDDEN_ITEM ' is included instead of it'content.

  Can someone indicate possible reasons?

• question to OBIEE 11g graphics

  Hi all

  I have an obligation to make a line-bar chart in the answers.

  the settings I use are best price, delivery price and closing price

  so the there are three bar display data for all would be the three metric. And there would be a line in the graph which should start from the firm price, then go the firm price + commit value and finally an end to the value of the sum of these three i.e. Commit + closed + better. So it would be a 3 bars and a trendline.

  To implement I have tried using the union of report 3 and calculates the sum of the required in reports trend line. Type of output I get is:
  

  Firm price |     Commit prices |     Best price |     Running total.

  1                              2                             3                         1                    (only closed amount)

  1                              2                             3                         3                    (Closed + Commit amount)

  1                              2                             3                         6                    (Closed + commit + Best amount)

  When I plot the graph, I get the values of the bar correctly. But instead of coming as trend line indicates a point on the graph with the value 1.

  I don't really know if the approach I'm taking is correct or not , kindly asking to please help me do the trendline on the chart.

  Kind regards
