I moved from Flash Charts to JS Charts for PDF generation support.
The X axis (Y axis for bar charts) labels now overlap and the Y axis values are truncated. Flash Charts displayed values as 4E10, 8E10 but JS Charts display them as 25,000,000,000 causing the values to overlap. Using fieldformat to format the numbers as 25B renders blank graphs.
Tried using chart properties like scale, majorTickSize, majorUnit, barSpacing, minorTickVisibility but the issue persists.
