Hi,
I am drawing FastScatter series from data in an XML file (incident 85597). For one of the series I need to draw some of the points with a different interior using color data which is also in the XML file. From reading the forum, FAQ etc the best/only way seems to be to override FastScatterPresenter.OnRender and manually draw the series. My problem is accessing the co-ordinate and color data in the xml file from within the overridden OnRender method. When OnRender is called the Points collection is null. How do I access the points collection populated from the xml file? I would rather not have the overhead of populating a points collection in the OnRender method every time it is called.
Many Thanks

Hi again,
I have succeeded in getting my XML based points into the points structure available in the OnRender function as shown in your sample, FastScatterCharts1288413969.zip, so can now change the point colour, size etc.
I now need to draw different groups of points in my FastScatter Series different colours. The colour data for each point is stored in the XML file with the point data. Is there a way to access this colour information through the XML from within the OnRender function?
Many Thanks

Hi Ganesan,
Thanks for your help, I am now able to colour the individual points of my Fast Scatter Chart, my code is attached.
I also have to draw a Column Chart with each column a different colour (FastColumnPresenter ?). I have tried overriding the OnRender function as before but this doesn't seem to work in quite the same way as for the Fast Scatter Chart. Do I need to do something different?
Thanks
