Real-time values

[User (Legacy)]

I'd like to add data to a graph in one second intervals (for example.)  I want the chart to develop as the data is added.  So, after 5 seconds, 5 points will be visible.

With the code below, I get no updates for 10 seconds, then all the data appears.

private void btnDataSet_Click(object sender, System.EventArgs e)

{

int i;

chart1.Gallery = SoftwareFX.ChartFX.Lite.Gallery.Lines;

// Set X/Y data

for (i = 0; i<10 ; i++)

{

chart1.OpenData(SoftwareFX.ChartFX.Lite.COD.Values , 2, 10); 

chart1.Value[0, i] = (20 + i);

chart1.Value[1, i] = (40 + i);

chart1.Legend[i] = (i + 1).ToString();

chart1.CloseData(SoftwareFX.ChartFX.Lite.COD.Values);

Thread.Sleep(1000); 

}

chart1.AxisX.Grid = true;

// Format Primary Y-Axis

chart1.SerLeg[0] = "Series #1";

chart1.SerLeg[1] = "Series #2";

// Format X-Axis

}

I have tried to change the OpenData call as follows

chart1.OpenData(SoftwareFX.ChartFX.Lite.COD.Values , 2, SoftwareFX.ChartFX.Lite.COD.Unknown); 

but it generates the following compile time error:

Argument '3': cannot convert from 'SoftwareFX.ChartFX.Lite.COD' to 'int'

Do you have any suggestions on how to do this?  Is it possible?

Thanks, Steve

Try converting your values to a float or real before you pass it to the chart.

You are "hanging" the thread that contains the chart when you make the call

to sleep().

I'm not sure what you want to do but if you want to refresh the chart every

10 seconds, you have to create a timer that refreshes the chart, you can not

put your process to sleep, the chart (and any other control you create) is

part of your thread and therefore when you call sleep() you are not going to

be receiving any Paint messages (or any other messages such as mouse,

keyboard, etc.).
