Hello Maciej,
The reason for this behavior is in the way RadChart databinding works. You have two options:
- Create the series you need -- in this case you have to set their DataYColumn property with the name of the column/field you need to plot.
- Let the chart create the series for you - it will create series for every numeric column/field in the underlying datasource.
In this case, you have created the series, but their
DataYColumn property is not set. So, RadChart will clear them and it will create new ones. That is why the
ShowLabels setting is lost. You will need to either set the
DataYColumn for each series or remove them completely and wire
DataBound event. There you will be able to loop through the actual series in RadChart and hide their labels like this:
Hope this helps.
