v1.1

[brenocq]

Hi everyone! I'm happy to announce ImPlot v1.1.

🚀 New Features

• Feat: Add flag to draw axis tick labels inside the plot area by @lstalmir in Feat: Add flag to draw axis tick labels inside the plot area #668

  • Use ImPlotAxisFlags_TickLabelsInside to draw the tick labels of the innermost axes inside the plot. Multi-line tick labels are also supported.

    ImPlot::SetupAxis(ImAxis_X1, "x", ImPlotAxisFlags_TickLabelsInside);

    

• Feat: Add vertical and horizontal markers by @bruno-f-cruz in Feat: Add Vertical and Horizontal markers #702

  • New ImPlotMarker_Vertical and ImPlotMarker_Horizontal, useful for raster plots and event markers.

    

• Feat: Add NoMove and NoResize flags to ImPlotDragToolFlags by @PysKa-Ratzinger in feat: added NoMove and NoResize flags to ImPlotDragToolFlags #720

  • ImPlotDragToolFlags_NoMove and ImPlotDragToolFlags_NoResize: the tool still reports clicks and hovers, but cannot be moved or resized and shows no move/resize cursor.

    v1.1-3-nomove-noresize.mp4

• Feat: Add IsLastItemHidden() by @forrestv in Add IsLastItemHidden() to allow application to see whether last item has been hidden #295

  • Also adds IsItemHidden(const char* label_id), which can be called before the item is submitted to skip expensive work for hidden items.

    IMPLOT_API bool IsLastItemHidden();
    IMPLOT_API bool IsItemHidden(const char* label_id);

• Feat: Display mouse coordinates while dragging or box-selecting by @Nahor in Display mouse coordinates when dragging/selecting #539

  v1.1-4-box-select-outside.mp4

• Fix: Snprintf truncation warning in legend demo by @brenocq in fix: snprintf truncation warning in legend demo #724

• Fix: Item color for PlotScatter now uses MarkerLineColor by @brenocq in 1351ab2

• CI: Build the demo with a restricted IMPLOT_CUSTOM_NUMERIC_TYPES; the example now builds against ImGui v1.93.0

📦 ImPlot3D v0.5 Released

Today we are also releasing ImPlot3D v0.5.

⚠️ Behavior Changes

No functions were removed or renamed in this release, but a few things behave differently:

• Shaded plots are more opaque. FillAlpha used to be applied twice, so fills looked lighter than requested (Fix double application of FillAlpha in shaded plots #717). It is now applied once; if you compensated by raising FillAlpha, lower it again.
• Drag tools (DragRect, DragPoint, DragLine) no longer react to clicks outside the plot area (fix: DragRect, DragPoint, and DragLine should not be clickable outside the plot area #719).
• ImPlotMarker_COUNT is now 2 higher because of the new markers; existing marker values are unchanged. ImPlotAxisFlags_TickLabelsInside uses bit 16 of the axis flags.
