Small Numbers in Chart

[David A. Gonzales]

Hi,
I am attempting to chart very small numbers (ie, 0.001 or smaller) and the numbers seem to plot correctly but the Y-Axis labels are strange. I am getting Y-Axis labels like 0.00, 0.00, 0.001, 0.001, etc. I have tried to use Auto as well as Set RangeType and tried to use various Format statements. This is 4.402.0.51. I can multiple the numbers by 1000 and that seems to get the numbers to display the Y-Axis labels correctly but would like to use the actual values if possible.

Thanks.
David

Here is a small sample that illustrates the problems I am having with the Chart control:

protected void FillPlot()
{
this.ChartWebControl1.Model.Series.Clear();

ChartSeries series1 = this.ChartWebControl1.Model.NewSeries("Plot1", ChartSeriesType.Line);
series1.Text = series1.Name;

series1.Points.Add(1, 0.007);
series1.Points.Add(2, 0.001);
series1.Points.Add(3, 0.009);

this.ChartWebControl1.Series.Add(series1);
this.ChartWebControl1.Redraw(true);
}

This shows the numbers being displayed but the Y-Axis Labels are strange.

Thanks
David.

Hi David,

My apologies for the delay in responding to you.

Thanks for using Syncfusion Products.

If your intention is to display very small value in Y axes means, please use RoundingPlace property in chartControl.

The following code snippet which illestrates how to set the Range and Roundingplace property in chartControl.

this.chartControl1.PrimaryYAxis.RangeType = ChartAxisRangeType.Set;
this.chartControl1.PrimaryYAxis.Range = new MinMaxInfo(0.000, 0.005, 0.001);
this.chartControl1.PrimaryYAxis.RoundingPlaces = 4;

Please let me know if this helps.

Thanks and Regards,
Rashidha.

Thanks. That worked. I had to write a couple routines to determine min, max and interval as well as determine the Rounding but works like a charm.

Thanks again.
David.
