draw dynamic text

[Stanfillirenfro]

I am facing another issue, ollowing up the problem with the values in OnRender().

I am trying to draw dynamic texts in OnDender(), but after failling to achieve the goal, I have deceided to draw the fixed text to check if there could be an issue with my values from the region Helpers. The fixed text can be seen on the chart, but not the dynamic texts.
Here is my code:

protected override void OnRender(ChartControl chartControl, ChartScale chartScale)
{
    SharpDX.Vector2 startPoint;
    startPoint = new SharpDX.Vector2(ChartPanel.X, ChartPanel.Y);​
    float canvasEndCoordinate = chartControl.CanvasRight;
    int xCoordinate1 = chartControl.GetXByTime(endX1);


   // Fixed text
   SharpDX.Vector2 vecMyTag = new SharpDX.Vector2(canvasEndCoordinate-75, startPoint.Y+35);
   SharpDX.DirectWrite.TextLayout textLayout1 = new SharpDX.DirectWrite.TextLayout(NinjaTrader.Core.Gl obals.DirectWriteFactory,
     "Here is my text", textFormat1, ChartPanel.X + ChartPanel.W, textFormat1.FontSize);
  RenderTarget.DrawTextLayout(vecMyTag, textLayout1, firstColorDx, SharpDX.Direct2D1.DrawTextOptions.NoSnap);

   // ​Dynymic text
   SharpDX.Vector2 vecMyTag = new SharpDX.Vector2(xCoordinate1, endY);
   SharpDX.DirectWrite.TextLayout textLayout1 = new SharpDX.DirectWrite.TextLayout(NinjaTrader.Core.Gl obals.DirectWriteFactory,
      "Here is my text", textFormat1, ChartPanel.X + ChartPanel.W, textFormat1.FontSize);
   RenderTarget.DrawTextLayout(vecMyTag, textLayout1, firstColorDx, SharpDX.Direct2D1.DrawTextOptions.NoSnap);​​​
}

I would be gratefull to you if you coud point out where I am mistaking.

Thanks in advace!

We appreciate your cooperation in this regard.


Are you seeing any errors in the Log tab of the Control Center?

It also looks like you are using the same variable names for the fixed text and the dynamic text (vecMyTag and textLayout1).

I also recommend taking a look at SampleCustomRender included in NinjaTrader 8 which demonstrates using SharpDX.DirectWrite.TextLayout.

Thanks NinjaTrader_Gaby for your help.

No!

I do not have "fixed text and "dynnaic text" at the same time in OnRender(). I write the code for the fixe text first and delete it to write the code for dynamic text.
I also have the X ad Y values in the print function in OnRender().

What could be the problem here?

Hello Stanfillirenfro,

What do you consider dynamic text?

Do you mean you want text that will scroll with the chart bars?
Below is a link to an example of this.

If you have print output, please provide the print output so we may assist with analyzing the output.

Are you printing the chart panel X and Y and H and W and comparing this to the X and Y coordinates of the rendered text?

Thanks NinjaTrader_Gaby for your reply!

What do you consider dynamic text?

I have some rectangles on the chart. I want to label each rectangle drawn and therefore I want text right after the rectangles.Since the rectangles increase their widths with the new bar, I want the text to remain right after the rectangles.

I have the coordinates as shown in the attached file. I am using these values to create the rectangles.

What could be the mistake I am making here?

Thanks in advance!

Hello Stanfillirenfro,

No output text file is attached to post # 5.

To confirm you are printing the coordinates for the TextLayout and these are within the coordinates and height / width of the panel?

Hello Stanfillirenfro,

What is this output?

Your prints should include labels that identify what each value is.

Print(string.Format( "ChartPanel.X: {0}, ChartPanel.W: {1}, ChartPanel.Y: {2}, ChartPanel.H: {3}, vecMyTag.X: {4} < ({0} + {1}): {5}, vecMyTag.Y: {6} > {2}, vecMyTag.Y: {6} < ({2} + {3}): {7} ", ChartPanel.X, ChartPanel.W, ChartPanel.Y, ChartPanel.H, vecMyTag.X, (ChartPanel.X + ChartPanel.W), vecMyTag.Y, (ChartPanel.Y + ChartPanel.H) ));
