Axis with fixed values on a stream

Hi,

is it possible to always show the latest defined range (via minimum and maximum) on a running stream?

I do have a continous stream adding values 1,2,3,4,5sec and so on. My x-axis should only show the last second. The labels should show 0 to 1 for example.

I can do this, always cutting the last second and changing x-values from 0 to 1, but this is not satisfactory.

Any idea how to do that? A plus would be if I can also zoom.

Thanks in advance

Use the AxisChanged event. Capture the ActualMaximum of your axis and then assign the Minimum in accordance. Good luck

Thanks everytimer for your quick response. But how to use the AxisChanged event? This does only fire if I zoom or pan not if the values increase.

I simply added the event like so:

var timeAxis = new LinearAxis(AxisPosition.Bottom, 0) { MajorGridlineStyle = LineStyle.Solid, MinorGridlineStyle = LineStyle.Dot, Title = "Time", Unit="s" };
PlotModel.Axes.Add(timeAxis);
timeAxis.AxisChanged +=timeAxis_AxisChanged;

So there is no min/max defined and the axis increases its values as needed.

I would like to get a (oscilloscope like) behaviour like this. That the X axis is fixed to a small window of 5 seconds of the newest data, here is an example:
