Plot disappear, is that a bug in 8.0.1?

[Guangtao]

I'm using WaveformGraph display a plot, I set the increment = -1, e.g.: plot.PlotY(data, start, -1);

When I zoom in several times, the plot disappeared, but when I move the graph, it appeared in some specialy area. I promise it's not a operation mistake, because I have another plot (increment = 1) as reference,  I think it's probably a bug. If it is, can you fixed it quickly?

Is there nobody can answer my question? It is a big problem. help me! Please!

Is that a visual studio code? or you can submit the code here to give us more information, and we can help you with it.

[Guangtao]

Sure. You can create a new project, drag a waveformGraph to form, and paste this code. And then zoom in by interaction mode (Shift + mouse). There's no other code, the demo can show you the problem.

            double[] a = new double[10000];

            for(int i = 0; i < 10000; i++)
            {
                a[i] = i;
            }

            this.waveformPlot1.PlotY(a, 10000, -1);

            // for compare
            WaveformPlot plot = new WaveformPlot();

            this.waveformGraph1.Plots.Add(plot);

            plot.PlotY(a, 0, 1);

What revision of Visual Studio are you using now?

[LipingZhao]

 Could you upload you whole project file to the forum.

Also you can email me your project file. Mail to liping.zhao@gmail.com

Thanks!

I use VS.net 2005. Just zoom in about  10 times, you will see the problem. I found some data, you just zoom in 3 times, it happened.

I have run your code and what you said reoccurred.

May be it's a bug of MS 8.0.1. I will give you a final conclusion as soon as possible.

Thank you. Is it possible fix it and then publish a patch or new version this year?
