tooltip_config now supports named character vectors to set
friendly display labels for custom tooltip fields. Use
c(column_name = "Display Label") instead of
c("column_name") to control what label appears in the hover
tooltip. Unnamed elements continue to use the column name as the label
(fully backward-compatible).Milestone line hover now works along the full line height: Previously, hover tooltips on single-date milestone vertical lines only triggered near the top or bottom endpoints. The hover mechanism is now a separate invisible marker trace distributed along the full height of the line, making the hover responsive anywhere along the line. Applied to both single-date vertical lines and narrow date-range milestones that fall back to vertical lines.
Reduced hover sensitivity for milestone lines: Lowered the hover detection distance from 20px to 10px, making the hover trigger only when the cursor is very close to the milestone line (within ~2.5 days at typical chart zoom), preventing accidental tooltip triggers when hovering nearby activities.
MM/DD/YYYY format with single-pass parsing. Dramatically
faster on large datasets. Users can specify alternative format via
date_format parameter.MM/DD/YYYY (default,
e.g. "09/15/2024"), Date class objects, or
custom formats via optional date_format parameter
(e.g. "%Y-%m-%d" for ISO).parse_date_flex() helper with configurable
date_format parameter (default:
"%m/%d/%Y").generate_hover_points() handles reversed dates
gracefully (End < Start) without crashing.format_label() renders date placeholders in
MM/DD/YYYY.test_project) uses
MM/DD/YYYY date strings.y = c(0.5, total_rows + 0.5) for consistent visibility
across the full chart.display_config$milestone$hide_label_levels parameter to
suppress text annotations for milestones at specific
label_level values while keeping hover tooltips intact. For
example, set to c(1) to hide all level-1 milestone labels.
Default NULL shows all labels (fully
backwards-compatible).label_level parameter to milestone markers for vertical
stacking of labels. Set to 1 or 2 to control which labels appear above
others when milestones are close together.milestones <- data.frame(
label = c("Kickoff", "Budget Approval"),
color = c("blue", "green"),
label_level = c(1, 2) # Level 1 appears above level 2
)
