Estimate when this could be addressed

I continually having to modify the source code to add a catch to a try block. This is an easy fix and will prevent the exception from crashing applications. Could the method in TeeChart.cs have the try catch statement added as shown below? public virtual void Draw(Graphics g) { bool old = chart.Auto...

Do you have a recommendation on how to chart data that is 1 dimension? Option #1 I would like to create a number line. The data would look something like a number line with a dark line drawn from the min to the max value of the data. Option #2 As another way to chart something like this would be to ...

Not sure I understand

This is because values are very similar and there's no significative differences between them in a logarithimic scale. Same would happen with non-logarithmic axes and a series with a constant y value (all y values being the same), in that case the constant y value would be represented as a single l...

The 7th series has 2 points but the points are made invisible with a transparency = 100. Here is a picture of what is charted http://tinyurl.com/4rmvna on the vertic...

I am impressed! I think that is the fastest response I have ever experienced in a support site that was not using chat software.

Thanks for the quick response.

Results

I just uploaded the bin\release build of the ChartMillionPoints test application. Your test hardware is definitely much faster than mine. I tested the release build on another machine. This machine was a 3 GHz, P4 processor, with 1 Gb of memory, NVidia GeForce 5200. It did perform better and I did s...

What I am using

I am using Steema's binary version 3.5.3146.24805 I know that is about 1 version behind the latest. I did what you had to do to run. My form_load looks like yours. I am curious, What does your output tab look like when running under visual studio? You should see entries for the debug statements here...

I see a different behavior

Oops on the code. Sorry I left that incomplete line in the code when I sent it. The video you reference was the behavior I would like to see. I am not seeing that behavior. Instead as I drag, the dialog will freeze because it is repainting the chart as I am resizing. I can move the mouse about a mil...

Suggestion does not work

The code suggestion does not work in the tChart1_Resize event. It appears that this event fires at the beginning of the dragging. I tried moving the code to the Form_MouseUp event. That did not help either. It appears when the Chart Resizes it still wants to Repaint as I drag the corner of the form....

If I have many points on a chart (~1 million) and I try to resize the parent form of the chart by dragging a corner of the window, the form freezes up. I have the chart's Anchor property set to Left, Right, Top, & Bottom. I would like to have the chart not resize until the MouseUp event fires. Any s...

Just need some advice

I don't expect support on this issue, just some friendly advise where to start looking. We do have the DrawValue method overriden and it is trying to draw the rectangle. The problem seems to go deeper into the System.Drawing.Graphics. I have a simple example where I have 1 large rectangle drawn. If ...
