Hi,
We have scatter plot in our client/server application where the data is aggregated on the server.
We use the scatterplot with different colored series, to product a weigthed scatterplot, where the color corresponds to the number of points with the given x-y values. (where the x and y are ranges of values instead of individual points)
When zooming/scrolling we would like to implement custom logic instead of the default zoom/sort. (to actually go back to the server and recalculate a more precice set)
During design we ran into 2 issues.
1. When Zomming on both X and Y Axis using the normal zoom function you would not get the exact zoom you would expect.
We then changed to the application to only Zoom on the X-Axis, with both Autogenerates and non autogenerated X-Axis.
We tried implementing the ZoomSettings_OnPropertyChanged, but we are unable to recalculate the actual values.
We even sometimes got a RangeEnd greater then 1 ?
2. Since we do our own zooming, is there a way to cancel the Client Zoom,
resetting the RangeStart&RangeEnd to 1 fires off the OnPropertyChanged Event again.
I think we are overlooking sometimes, so your help would be appriciated.
Regards,
Marinus

Do not match the visual selection of the Zoom. We have an Amount Range on the XAxis, ranging from -2 mil, to 8 mil, selecting -0.5 mil to 1 mil, gives +1.2 mil to 1.4 mil give or take.ChartArea.AxisX.ActualMinValue + (ChartArea.AxisX.ActualRange * ChartArea.ZoomScrollSettingsX.RangeStart)
ChartArea.AxisX.ActualMinValue + (ChartArea.AxisX.ActualRange * ChartArea.ZoomScrollSettingsX.RangeEnd)
