Draw text on the XY graph

• Draw text on the graphic waveform Plot

  I need to understand how to draw text on a waveform graph during execution. This could be a text box, a picture of the text, a label and an additional plot with text... etc.

  Yes, I know a graph would be better than this, but need to use a graphic for my application.

  The graph is updated every second, and new data are added to the history of the ranking. (Which means that the chart bigger every second) So if I draw the text above or behind the table, I'll have to update their location every second. I'll have to use card to XY Coords in an event, (mousedown or mouseup) to place the text (or image of the text) in the field where the user clicked.

  Step 1 to resolve this problem is to find first class, learn how to draw or text on the plot of the graph area.

  Does anyone have ideas of how this could be accomplished, or some ideas of a sneaky work around to make this work?

  Example:

  

  Unfortunately, graphics (graphic and graphic waveform XY) have support Annotation and slider, exposed programmatically through properties, but the array of waveform is not.

  What you could do is to place an indicator of 2D image that corresponds to the size of the chart above.  Make the value of the image that you draw be transparent and just print the text with transparent backgrounds.  However, I do not know the considerations on the performance of it - many times user interface elements, overlap (portions of even transparent) can cause problems of performance due to forcing redesigns... then again maybe a graph is always be redrawn in any case.

• resize the text of the xy graph axis

  Hello, I have a question about XY charts:

  I want to have both XY-graphs with identical sizes aligned perfectly to have a nice comparison of the separate sets of data without their trace on the same graph. However, I can't find out how to set the width of the text y axis. Because now when the width of the texts are not the same, even if the whole graph has the same region and departure (continuous line on my pcture), areas of land are a little off (indicated by arrows)

  Peux I put somehow the width of these texts, as well as areas of land worth? Right now I use 'Position' and 'Size of the area of the land' properties of charts XY to make them also of size.

  Thank you

  

  Your VI has not all data stored in it as a default.

  When I used the %10.0f on your VI and set the scales, the results were better than nothing, but not perfect.

  I don't know if this method would work perfectly.  With a font that is not fixed width, the actual width of the text could very slightly.  The width of the different numbers could be different, and the width of a space character to fill the text when there are fewer numbers can be different.

• How to draw text bordered on Bitmap usgin class Graphics?

  Hi guys.

  I'm drawing text on a line graph.

  Here is the example.

  The text color is black. Border is white (edge of letters).

  How to draw like this?

  Thanks in advance.

  If you are interested in a vaguely similar effect, but without all the subtle shadows, I have a suggestion. Draw the white text, several times, gap between the nominal position of a pixel or two in different directions and then draw the text in black at the nominal position. The idea is that white copies create an enlargement of each letter which becomes an overview when you draw the black letter on it. You may need to do this a letter at a time, allowing more space between the letters, rather than draw the entire chain at the same time.

• drawing text on BitmapField

  Hi all

  I'm having a problem with BitmapField.

  I'm tring to draw text on the scope of the Bitmap.

  The purpose of this is that if the field has the focus, change image and attract white text and vice versa.

  But it seems that the text drawing image behind.

  Please help me on this.

  Thank you

  DK.

  Here is the code:

          ttsField = new BitmapField(tab_off, BitmapField.FOCUSABLE|BitmapField.FIELD_RIGHT|
                  BitmapField.FIELD_VCENTER)

              if (g.getBackgroundColor() != 3098850)
              {
                  g.setBackgroundColor(0xfafafa);
                          g.clear();
              }
              super.paint(g);
          }
          protected void drawFocus(Graphics g, boolean on)
          {
  //          if (hasFocus)
                  g.setColor(0xffffff);
  
                  g.setFont(Utils.BBMillBankTall(12, Font.BOLD));
                  g.drawText("Text to Speech", 0, 0);
                  super.paint(g);
              }
  
          };
  

  You have your sequence of events backwards.

  Call the super.paint (first), then the text above the image bitmap drawText().

• 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 )

• How to type vertical text from the bottom up with the right orientation for a graph?

  How to type vertical text from the bottom up with the right orientation for a graph?

  Hello! Below, I'll demonstrate how to have vertical text in two different ways.

  Example 1:

  1. below, I have a graph and want to label the vertical axis.

  

  Select the text tool, and then the Vertical text tool.

  

  2 with the vertical Type tool, I tap on my vertical label.

  

  3 with the move tool, then I can orient the text in a position desired, as shown in the examples below.

  

  

  If this isn't the desired orientation of the vertical type you would like. I have the example 2 below.

  Example 2:

  1. After typing my text vertically with the Vertical Type tool (in example 1), I want to move to a horizontal position. I can go up to the options panel and select the icon "show/hide text orientation", surrounded by below. It will pass the text back and forth between vertical and horizontal.

  

  

  2 after the passage of the text to be horizontal, I want to change the orientation of the text, so it is aligned with my vertical axis.  Go in Edit > transform > Rotate as shown below.

  

  3 you want to can Rotate the text as indicated below.

  

  

  4 text is not in the right position we want, so we have to move the text, as illustrated below. Press enter/return to perform the complete transformation.

  

  5. the text is shown below.

• Multiple and different axis-related channels are on the same graph

  Hello

  I searched the forums and google trying to find out how to trace my 48 channels in a single chart and according to the plots of units he value axis 1 of 4.

  I have 48 channels all of them share the same time base axis.

  48 channels are mixed of flow, pressure, Temp and other bag. The units are located in the 'Units' property to the string.

  I would have 4 axis to account for my 4 units and hold all 48 channels to draw on the same graph, aloted to the axis of sorts.

  Thank you I have maybe for what is right, as it is a small segment of my script script. Help, advice or information would be greatly appreciated. I am struggling to find documentation to know where to start with this.

  Hi KR,.

  After talking to my colleagues, I think that you can now have a solution to this, but for the benefit of third parties, the solution is to use "Related curve" scaling in the axis system display 2D of the pane window VIEW. To have this feature enabled you must be using n or n axes systems.

• Update the text of the label on a XControl via a property

  Hi all

  I write various programs to help with the debugging of embedded systems. I often need to convert a value to byte into pieces and then show which of these bits are true/false. This is easily done by using the convert-bool-Bay VI. However, I would like to create a control that will allow me to display a name for each field of bits - a bit like the way records are described in the data sheets. The control must be a bunch of buttons, and then I can show the bits are true/false, and use the label of the button to hold the name of bit field.

  I went from one way to the creation of this feature in an XControl as this seemed the best. My group of updates to Boolean values correctly according to the value of byte brought into control. However, I use a property to set the Boolean control label text (names of bit fields). My debugging shows that the text is assigned to the label of the control, but the control panel never changes. I tried synchronous updates, and by forcing a new drawing of the Panel using DeferPanelUpdates does not.

  I would be grateful for any help on this - VI and XControl demonstrating the issue is attached.

  Thank you

  Ray

  Probably, because you try to change the text of the label.  Try to change the text of the legend...

  For each boolean, choose "visible elements of legends '...

  

• Draw a rectangle in a graph

  Hi, I want to programmatically draw a rectangle on a chart XY (XY Graph.vi Build). I know where the 4 points are on the coordinate chart but I can't yet draw using the block Rectangle to draw. Could you please help me how can I draw a rectangle in a graph. I am attaching the photo to this message

  Hi guys,.

  I thought it was interesting questions - and, although I had not tried anything quite like this before, I thought I would give it a whirl. smercurio_fcsuggestion was excellent - I find the code referenced in LV example finder, in the fundermentals > graphics & graphics > plot pictures folder.

  Attached are 2 pieces of code.

  DrawRectangle on Graph.vi allows users to define the rectangle by cluster of façade.

  

  DrawRectangle on graphic .vi (events) allows the user to define the rectangle by clicking and dragging on the chart. Please note that the code requires that you start from the upper left corner of the rectangle, and drag to the lower right. But isn't that a creative logic would not solve - if you wanted a bit more flexible code.

  

  You should also know that I have not spent a lot of time on the code, so it is not perfectly architected. But we need to think!

• several land 3D on the same graph

  Hello

  I use the 3D library CW graphics.

  I would to draw 3D curves on the same graph: is it possible?

  To draw my curves, I use: CW3DGraphLib__DCWGraph3DPlot3DMesh (graphHandle, NULL, xVt2, yVt2, zVt2, CA_DEFAULT_VAL)

  Thank you...

  Adeline

  OK, it's great that I found that it did not work!

  I had to add in some places:

  CW3DGraphLib_CWPlots3DItem (plotsHandle, NULL, CA_VariantShort (1), & plotHandle);
  CW3DGraphLib_CWPlot3DSetMultiPlot (plotHandle, NULL, VTRUE);
  CW3DGraphLib_CWPlots3DItem (plotsHandle, NULL, CA_VariantShort (2), & plotHandle);
  CW3DGraphLib_CWPlot3DSetMultiPlot (plotHandle, NULL, VFALSE);

• Multiple channel for the XY graph

  Im trying to draw a table 1 d in the y-axis and sometimes in the X axis. When I probe values since the wire connecting the XY graph, I see the values also perfect that I need them. But I do not see the values on the graph.

  Able to do the same thing with a waveform graph, but a chart XY im gives me a few more flexibility and benefits...

  Thank you

  Gokul Krishna S

  Hi Eureka,

  There's a Subvi, that you do not attach with this VI, and I can't run it.

  Part of your problem is that your x axis has a single value rather than an array of values.  If you right-click on your chart and select Properties, then go to the locations tab, you can change views of marker.  If you do something larger than a single pixel, you should be able to see it on the screen.

  Please also take a look at This example of community to the XY graphs.

  Thank you
