I am experiencing scalability issues with the GXT3.0 scatter charts. I am implementing an application that requires plotting of several thousand points. It appears everything works fine up to about 500 points, and then the points no longer appear correctly. In addition, when one goes beyond 300 to 500 points, the selectionevents and mouseoverevents return the wrong index to the ListStore. Just wondering if anyone had encountered this issue or if it is likely I am doing something wrong. Thanks.
Thanks for the report. This has been fixed in SVN and will be in the next release. ScatterSeries was erroneously using LineSeries shrink method when calculating its points. LineSeries uses shrink when trying to display more points than there are pixels wide.
