Switching UserDefined ChartSources
lazarus / 55-TAChart

In my current project, the data to be plotted are elements of items
that are stored in a special list. To get access to the data, I am
using a UserDefinedChartSource attached to a single series. Now I have
a combobox which allows to select the element to be plotted. A "case"
instruction in the chartsource's  OnGetChartDataItem picks the correct
element. This works fine, but the axis of the chart is not updated.

How can I force the axis / series / chartsource to update the axis
according to the new data?

Did you call UserDefinedChartSource.Reset ?

No. That's what I've been looking for. Thank you.
