Problem configuring X axis manually

[Ambar Kulkarni]

Hello Everyone,

I am creating a chart to display real-time data that is "polled" every 5 seconds. Additionally, my chart can contain multiple data series all of which will be spline. If I let the chart auto calculate the X axis bounds and ticks, it is extremely slow in displaying initial values. So I want to set the X axis manually. Here is the code I have so far:

radChart1.DefaultView.ChartArea.AxisX.LayoutMode = AxisLayoutMode.Normal;
radChart1.DefaultView.ChartArea.AxisX.IsDateTime = true;
radChart1.DefaultView.ChartArea.AxisX.DefaultLabelFormat = "T";
radChart1.DefaultView.ChartArea.AxisX.AutoRange = false;
DateTime MinVal = DateTime.Now;
DateTime MaxVal = MinVal + TimeSpan.FromSeconds(UpdateInterval * (NumDataPoints + 1));
radChart1.DefaultView.ChartArea.AxisX.AddRange(MinVal.ToOADate(), MaxVal.ToOADate(), 1.0);
radChart1.DefaultView.ChartArea.AxisX.Step = 0.05;
radChart1.DefaultView.ChartArea.AxisX.LabelStep = 1;

Note that the default value for UpdateInterval is 5 and NumDataPoints is 10

However, using the above code, I only get two ticks on the X axis. What I really want is that the number of ticks should be the same as NumDataPoints and they should be equally distributed between the Min and Max of the X axis range. How can I achieve that? I have tried playing around with Step and LabelStep values but did not get anything different.

Any help would be greatly appreciated.

Thanks

Hello Ambar Kulkarni,

Have you taken a look at our example here? It shows how such scenario can be accomplished. It should be no more difficult to do it if you are using a manual range X Axis.
