Dear Christopher,

Thanks for this,

I was rather afraid it was the case

I need to plot an ECG waveform. The signal is captured at 300 Hz in 1 second (300 value) records. I want to display it using a refresh rate of 25 Hz (40 mSec), plotting 12 values on each cycle. My X axis has a maximum value of 3000 (10 secs). I'm using 'Fastline'. My prototype starts well enough, bu...

Excellent!!

Happy Christmas

Is there any progress with the UWP version of TeeChart? - In an earlier post it was mentioned that one would be available in the autumn.

OOPs - I forgot to specify:

fastLine1.TreatNulls = Steema.TeeChart.Styles.TreatNullsStyle.DoNotPaint; - This fixes the problem!

Screenshot.jpg I'm creating an 'Oscilloscopic' ECG system which requires that datapoints be transparent when the second and subsequent screen scans are made. The problem is described fully in the post on oscilloscopic emulation. The solution (which was recommended by you) works very well in regular...

When I replace the method (as shown below) and attempt to re-compile, I get: Error 1 'Steema.TeeChart.Drawing.GL.GraphicsGL.TextOut(int, int, string, bool)': no suitable method found to override Code Snippet: //public override void TextOut(int x, int y, string text) //{ // TextOut(x,y,0,text); //} p...

Dear Christopher,

I have the source code version. Could you let me know what to do?

Andy

Thank you. - I'm still extremely pleased with the graphs I generate!

Dear Christopher, I've solved questions 1 and 2: 1. The gray lines are the Grid lines of the Depth Axis and are removed by setting Axes.Depth.Grid.Visible to false. 2. In my version of Teechart (Steema TeeChart for .NET Source Code 2015 4.1.2015.08060) changing the font in properties (eg Axes.Bottom...

EffectOfOpenGL.jpg I'm afraid I'm still having problems. In the image above, the same chart (without series data) has been rendered with and without OpenGL active. I commented in or out the code below to achieve this effect: Steema.TeeChart.Drawing.GL.TeeOpenGL openGL = new Steema.TeeChart.Drawing....

This illustrates the absence of labels with openGL. Also,how do I remove the dashed gray lines from the (invisible) left wall?

I'm attempting to emulate the surface chart entitled "XZ Grid with Y displacement" from your gallery. I can't find it in your samples. I can reproduce the charting behaviour by activating Open GL, but then the axis labels are not shown properly (See above).

Can you help?

Steema.TeeChart.Drawing.GL.TeeOpenGL openGL = new Steema.TeeChart.Drawing.GL.TeeOpenGL(SurfaceChart.Chart);
openGL.Active = true;
openGL.ShadeQuality = true;

Can you show me some code which 'turns on' OpenGL and implements the continuously colored surface as shown above?
