graph of the intensity

How can I get my intensity graph to display the data of each electrode in a 9 x 9 table? I need to be able to see which box is which.

  • draw lines on the graph of the intensity

    I want to draw lines on the graph of the intensity.

    I am already looking for some questions before.

    I know there is a vi could draw line on the graph of the intensity by dragging the mouse.

    But I need more precisely what set the length and the angle between the horzontal line.

    The setting is very ideal for me. But I don't know how to use it in the intensity chart.

    Is there anyone can help or give some advice?

    Your example is not so great because it uses 100% of CPU on a kernel at any time, do nothing.

    Here's a quick rewrite of my old example here. He draws an angle with the specified length and angle to where you click on the chart. This should help you get started. Modify if needed. (Also remember that trigonometry is much easier when using complex numbers )

  • DateTime on x-axis of the graph of the intensity

    How can the x-axis of a graph of intensity be configured to the DateTime data type, similar to the graphic waveform XAxis?  You can set the FormatString DateTime MajorDivisions, but has no way of installing the x-axis values.  Waveform curve has a foot (double [], DateTime, TimeSpan) function that will implement the XScale with the correct DateTime values, but the graphic intensity doesn't seem to have a similar capability.  I tried to configure the graphic intensity YAxis MajorDivisions DateTime Format string and pass then the plot function Tick values for the yScaleStart and YScaleIncrement, but it does not work probperly.  MS2012 release notes say that the curve of intensity has now an automatic formatting for displaying DateTime on axes X and Y.  I tried to use this feature to test the DateTime X and the ability to axis Y; However, the function of automatic formatting is not available for the chart of the intensity.  Any help is appreciated.

    Thank you!

    Hello

    Try the following code piece.

                // Set the label format correctly            intensityYAxis1.MajorDivisions.LabelFormat = new NationalInstruments.UI.FormatString(NationalInstruments.UI.FormatStringMode.DateTime, "g");
                intensityYAxis1.Mode = NationalInstruments.UI.IntensityAxisMode.AutoScaleExact;
    
                double[,] data = new double[100, 100];
    
                for (int i = 0; i < 100; i++ )
                {
                    for (int j = 0; j < 100; j++ )
                    {
                        data[i, j] = (i + j) / (colorScale1.Range.Interval * 2);
                    }
                }
                // IntensityGraph only understands double values. But graph can interchange the data value from different types using the DataConverter provided by NI.
                intensityPlot1.Plot(data,
                    0,
                    1,
                    (double)DataConverter.Convert(DateTime.Now, typeof(double)),
                    (double)DataConverter.Convert(TimeSpan.FromDays(1), typeof(double)));
    

    It will be useful.

  • How can I specify pixels in the graph of the intensity?

    Hello

    I want to specify the number of pixels in the in the intensity chart. I have 56 values want to display. How can I do this?

    Hi jerryvdk,

    By specifying the number of Pixels, you hear, allowing only a specific land area size of the chart itself?

    You can change this through the use of a property node.

    Steps to change the plot area size:

    • Right-click on the graph of the intensities.
    • "" "" Scroll create "property Node" plot area "size" all items.
    • This will create a property node that will allow you to change the property of area of the draw of the intensity card.

    By specifying a space of draw of the 56 x 1, this would allow a 56px draw area size fate. Is that what you meant?

  • With the help of the graph of the intensity

    Hello

    Currently, I have a problem with the graphics of the intensity. I use the Toolbox of the time frequency in Labview. Currently, I am having a problem where I had to plot the spectrogram of the signal. I tried to maintain a plot of the spectrogram to 0 for 4S and another 4 s to 8 s. I'm trying hard to draw the graph of the two together, to form a parcel from 0 to 8 seconds, in the spectrogram. In addition, the time axis will continue to increases in 4S interval with a spectrogram updated. I wonder how can I realized by having two spectrogram with two different time interval to display a common conspiracy? Thanks much for the advice.

    Hi kengkc,

    Correct me if I'm wrong, but you say that you have the data for the first 4 seconds of your acquisition (t = 0 to 4) and 4 seconds following your acquisition (t = 4 to 8) and you want to combine them into a plot? I guess that since you were able to draw in a graph of intensity to begin with, they are already in the tables.

    If that's what you want to do, you can easily concatenate your arrays using the Array function build (which means to add a table at the end of another person). Add your function Array of build of the subpalette of the table and make sure that you right-click and choose concatenate arrays so that you get more dimensions in your resulting table. Then expand the function Array build so that you can wire your matrices inside.

    Please refer to the attached screenshot to get an idea of what I mean.

    I hope this helps.

  • Draw the new lines on the graph of the intensity

    I'm trying to attract the XY axes by an arbitrary point on a graph of intensity. I can draw two lines across the image (suite of messages like this link below), but they don't really seem FDNE to the top one the coordinates I spesify. I know that I have to correct the fact that the vertical scale increases from top to bottom, but how do I draw lines to the (x 0, y0) position I spesify? It seems that the lines are superimposed on the image, but not related to the axes of the actual intensity chart.

  • Fade colors in the graph of the intensity

    Hello world

    I did a program where I read a 2D array and draw this picture in a graph of intensity.

    I was wondering if the colors in the chart weaken each other, preferably in a vertical position (columns). The idea is that digital data becomes viewed as a genetic profile.

    I added a picture of the graphics path.

    Thank you.

    Without manipulating the table, no it's not possible.  I had an idea about the exchange of idea to solve this problem, I recommend that vote you for it.  Anti-aliasing or smooth intensity plot

    As says the idea, see this post for workarounds.

  • Table of standard color for the graph of the intensity

    Hi all

    I am trying to change the color table of a graph of intensity of some tables in color standard, such as 'rainbow', 'gray', 'seismic', 'waves of lava","hot metal","purple haze", etc.. I can't find not "Rainbow" and "grey" somewhere for the examples, but not others. I tried to generate these color tables myself using the example «...examples\general\graphs\intgraph.llb\Create Table.vi IntGraph color, but the result was far from good.

    Can someone teach me how to generate these color tables? Thank you in advance.

    Kind regards

    Mario

    Hi GerdW,

    I'm not sure of the exact way to do it, but I did a simple vi based on your idea. The vi to retrieve the color table I want in the table format, subject me to load the bitmap file that contains only the color scale. Some raster color table constants are included in the VI for those in need. Please see the attachments and give me your comment.

    Kind regards

  • LabVIEW hangs with in the intensity chart

    Twice this morning, LV2010 weighed ("program is not repsonding") when I tried to put a graphic on my front intesity.  In one case, I copied the graphic in an example program OR my VI.  When I tried to reposition the chart on my forehead panael, LV unresponsive.  Same thing happened when I tried again; the second time, I have the graph of the intensity of the palette of tables and graphs.  I LV 2010, version 10.0f2 and windows XP.  Thank you.

    Hello!

    The following KnowledgeBase explains why this could happen.

    http://digital.NI.com/public.nsf/allkb/9A8FB888BFCED9658625721500434A31

    Basically, this table might contain a large amount of data, and when you move, LabVIEW must reorganize all this information in RAM as you move the chart. You can write smaller data, or save all data in a separate table in the table at the end of the execution so you can save it. If you want to view a chart later, simply enter it in a graph.

  • How can I draw the intensity in real time of a picture in time real (imaq 1394)?

    I have a firewire camera.

    I hooked up my camera to my pc with labview and now I display image in real time. How can I draw the intensity of a region dependent on time?
    Y - intensity
    X - time... I would watch the variaions real-time intensity...

    Thanks in advance

    The light meter example is pretty much what you want to do. It is located here:

    \National Instruments\\examples\Vision\2. Functions\Light Meter\Light meter Example.llb\Light meter Example.vi

    In the example, the x axis are the number of iteration, but it is easy to modify to use a graphic instead of a graph and chart the time instead.

    Hope that helps.

  • How Apple Watch to know or to calculate the intensity of my workouts?

    Hi all

    I used my Apple Watch now since some time in combination with the application of activity for different types of workouts such as running etc and I am curious about the watch or the activity app knows the intensity of a workout as a race.

    The rate watch or app works just like a similar race or does it somehow make a difference if a race is more or less "hard"?

    I am interested in this because I think that there is a difference if you go on a relaxed atmosphere, 10km run, or if you for example one very hard works on a mountain. Can watch it / app don't know if you use for example up the Hill?

    I was recently on a very relaxed ran about 10 km with my girlfriend. After such a race I feel very exhausted, but the activity app still said I burned some calories. Now another day I went to a really hard and fast race up a hill which was a lot however shorter, only about 6km. In this case the activity app said I burned fewer calories than on race relaxed and I really can't believe that run if I work very hard compared to a relaxed atmosphere.

    That's why I wanted to know how it actually works and hope someone can answer me.

    Thank you and best regards,

    Thomas

    Hi Thomas

    When follow you an activity using the application of the training session and specify a type of activity, your watch uses the most appropriate sensors and data sources to estimate the outcome of this workout.

    For example, when you save a run in the open air:

    • If you also take your iPhone along (with compatible Bluetooth and location Services), your watch can access the GPS of the iPhone data when estimating the PACE and distance.
    • If you do not take your iPhone along, the watch relies on data from the accelerometer in the estimate of the PACE and distance.
    • Data from the heart rate sensor is used during the estimation of the Active Calories, including calculations which are adapted to different activity types.

    Calibrate your watch helps improve the accuracy of the different estimates made by the activity and workout app app. More information and instructions for calibration of your watch are available via the link below.

    Estimates of the results will also depend on your personal information. To verify that this is correct - and update over time:

    • On your iPhone, in the application of the watch, go to: My Watch tab > health > edit - tap and adjust the settings, then press on in fact.
