Area-specific drawing options.
<insightdock/area_chart.h>
struct AreaChartOptions;
| Name | Description |
|---|---|
dash | Alternating on/off stroke lengths in pixels for the top edge; empty = solid. |
data_labels | |
gap_policy | How NaN/Inf/missing values are drawn (default: break the line). |
line_width | Stroke width when show_line is true. |
point_radius | |
point_shape | |
show_line | Draw stroke on top of each area. |
show_points | Point markers at each data point along the top edge; off by default (Chart.js-style). |
spline | Cubic (Catmull-Rom) interpolation between points instead of straight segments. |
stacked | Stack series polygons instead of overlapping. |
stacked_percent | 100%-stacked: every category is normalised to 100, so the chart shows each series' share. Implies stacking; the y-axis runs 0-100% and a category whose total is not positive is empty. |
step | Staircase instead of straight segments (takes precedence over spline). |
