ganttify 0.1.82025-12-19

New Features

  • Custom Tooltip Fields: Added tooltip_config parameter to display custom columns from your data in hover tooltips. Specify which columns from wbs_structure and activities to show. Fields that don’t exist or have empty/NA values are automatically hidden.
tooltip_config = list(
  wbs = c("Owner", "Budget"),
  activity = c("Status", "Agency", "Priority")
)

ganttify 0.1.72025-12-04

New Features

  • Dynamic Minimum Bar Width: Activities and WBS items with very short durations now remain visible at any zoom level. The chart dynamically adjusts bar widths when zooming to ensure all items are visible, while preserving original dates in hover tooltips.

Improvements

  • Switched from hovertext to hovertemplate for more consistent hover behavior across all bar types.
  • Removed deprecated short_activity_indicator parameter (replaced by automatic dynamic bar width).

Bug Fixes

  • Fixed hover tooltips showing incorrect format on dynamically resized bars.
