8 months ago Hi I am even facing the same issue can anyone let me know why is this issue coming
Drawing combined chart with line and bara data. All procedure with graph in try-catch block and still crashes. Is it expected behaviour?
(Off top. There also was errors, if i put in combined chart only line data after drawing it with line+bar data (loaded line+bar, changed in settings to only line, refreshed page -> crash). So i solved it just hiding bars, not best solution because of some useless operations, but it works)
Where i can place "if" condition to not draw graph in this case?
