Hi, has anyone here written any custom tchart series at all? I have my nice new TLineSeries descendent that works all nicely, except for the fact that when I select "add series" from the TChart property editor, I get an access violation.... I'm thinking it might not be finding a bitmap resource for the gallery, the code I'm using is: implementation {$R UnitBmps.res} ..... Procedure RegisterUnitSeries; begin RegisterTeeSeries(TUnitLineSeries, 'Unit Line', TeeMsg_GalleryStandard,2); end; initialization RegisterUnitSeries; end. The file UnitBmps.res contains one bitmap resource called TUNITLINESERIES. Does anyone here have any pointers?
