Version 4.2.x

Version 4.2.1

30th January, 2026

Enhanced the behavior of Horizontal Legend Scrolling to work independently from vertical scrolling. This ensures smoother navigation and prevents horizontal scroll actions from affecting vertical movement. Refined scrollbar sizing to improve alignment and prevent extra padding, resulting in a cleaner legend layout.
FusionCharts 4.2.1 introduces maxpadding, minpadding, and strictpadding attributes to configure Axis Domain Padding in TimeSeries charts. When strict mode is enabled, charts can render with explicitly defined minimum and maximum values. Default auto‑padding behavior remains unchanged for all other cases.
Updated the jsPDF dependency to version 4.0.0 for PDF export, addressing security updates while maintaining existing PDF generation behavior unchanged.

FusionCharts version 4.2 introduces the ignoredepthforlineplots attribute, which, when set to true, makes the leftover line plot in an mscolumn3dlinedy or stackedcolumn3dlinedy chart act as a 2D line. Otherwise, the line continues to appear in 3D.
FusionCharts version 4.2.0 introduces support for inverse axes in Scatter and Bubble charts. You can now reverse the X and Y axes by setting the new attributes reversexaxis and reverseyaxis to true in the chart configuration.
