MindFusion.Charting for WinForms V4.3.1Version majeure26 oct. 2026
Fonctionnalités
  • Grid heatmaps
    • The HeatmapChart control and HeatmapRenderer can now render heatmaps as a structured grid of cells in addition to the continuous radial gradients. Set the HeatmapLayout property to Grid to partition the plot area into rows and columns defined by GridRows and GridColumns. The color of each grid cell is calculated by interpolating series data using the algorithm specified by Interpolation:
      • Accumulative - samples radial falloff intensities at cell centers based on data point coordinates and radius.
      • InverseDistance - applies Inverse Distance Weighting (IDW) spatial interpolation from surrounding points.
      • NearestNeighbor - assigns the intensity value of the closest data point to each cell.
    • Grid cell borders can be customized using the ShowGridLines and GridLineColor properties.
  • Axis interval alignment
    • The Axis class now features an automatic "nice number" interval calculation algorithm that snaps auto-calculated intervals to clear, human-readable increments (powers of 10 scaled by 1, 2, or 5) rather than arbitrary decimal fractions:
      • The AlignIntervals property (default true) controls whether calculated intervals are rounded to the nearest nice numbers.
      • The TargetDivisions property specifies the preferred number of subdivisions across the visible axis span (defaults to 10).
      • The read-only EffectiveInterval property exposes the active step size used by AxisRenderer.
  • Miscellaneous
    • BubbleRenderer and ScatterRenderer now dynamically adjust the measured axis data range to include bubble and scatter shapes, preventing them from clipping at plot edges.
    • Added the OuterLabelOffset property to PieChart, allowing you to customize the distance between outer labels and the pie circle.
