AreaChart | Area chart — filled polygons from series values down to the baseline. |
AreaChartOptions | Area-specific drawing options. |
BarChart | Vertical bar chart. |

CartesianChart | Abstract base for charts with x/y axes, categories, and multiple series. |
CartesianOptions | Axis labels and scale behavior for Cartesian charts. |
Chart | Abstract base for all chart types. |
ChartExporter | Unified chart export API — render once, save or encode. |
ChartOptions | Common styling and layout for all chart types. |
ChartResult | Result of a chart export operation — either a value or a ChartError. |
ChartResult<void> | ChartResult specialisation for operations with no return value. |
ChartTheme | Visual style applied to any Chart via Chart::apply_theme. |
Color | RGBA color with 8-bit per channel. |
ComboChart | Mixed bar-and-line chart on a shared axis. |
ComboLineOptions | Drawing options for line series in a ComboChart. |
DataLabelOptions | Per-chart configuration for drawing the value of each mark directly on the chart. |
DataSeries | Named data series for Cartesian charts (bar, line). |
DecimationPoint | A single (x, y) sample for decimation. |
DrawTarget | Pixel-space drawing surface shared by all built-in charts. |
ExportCapabilities | Chart/build capabilities; querying does not draw, clone or validate input. |
ExportOptions | Options controlling render quality and output format. |
Font | TrueType font rasterizer (stb_truetype backend). |
Histogram | Result of compute_histogram: edges.size() == counts.size() + 1. |
HistogramOptions | How compute_histogram bins its input. |
ImageBuffer | Packed RGBA image (row-major, top-to-bottom). |
LegendOptions | Legend placement and visibility. |
LineChart | Multi-series line chart. |
LineChartOptions | Line-specific drawing options. |
Margins | Padding around the chart plot area, in pixels. |
PieChart | Pie chart rendered to an ImageBuffer. |
PieOptions | Pie-specific layout and styling. |
PieSlice | One slice of a PieChart. |
Point | 2D point in pixel coordinates. |
RasterTarget | DrawTarget that paints into an ImageBuffer (the original raster path). |
Rect | Axis-aligned rectangle (x,y = top-left, w,h = size). |
ReferenceBand | A shaded threshold band (e.g. a target range) drawn over Bar/Line/Area/Combo charts. |
ReferenceLine | A threshold/annotation line drawn over Bar/Line/Area/Combo charts. |
Scale | Maps a data domain [min, max]to a pixel range. |
ScatterChart | Scatter chart with continuous numeric x and y axes. |
ScatterOptions | Scatter/bubble layout and styling. |
ScatterPoint | One point in a ScatterChart series. |
ScatterSeries | One data series in a ScatterChart. |
SeriesStyle | Optional per-series overrides of the chart-wide line/marker options. |
DashPattern | Alternating on/off stroke lengths in pixels (e.g. {6,4}); empty means solid. |
FontData | Raw TTF file bytes. |
FontDataPtr | Shared, immutable TTF bytes — cheap to copy into many charts and fonts. |
| Name | Description |
|---|---|
BarMode | How multiple series are drawn within each category. |
BarOrientation | Bar direction. |
ChartError | Reason a chart export operation failed. |
ComboSeriesKind | Geometry kind for each series in a ComboChart. |
DataLabelPosition | Where a data label is anchored relative to its mark. |
GapPolicy | How a missing value (NaN, Inf, or a series shorter than the category list) is drawn in line, area and combo-line series. |
OutputFormat | Output encoding format for ChartExporter. |
PaletteKind | Named palette for automatic series/slice coloring. |
PdfBackend | PDF embedding strategy when writing or drawing PDF output. |
PieLegendPosition | Legend placement for pie charts. |
PointMarkerShape | Shape drawn at each data point marker (line/scatter/combo charts). |

TickFormat | How y-axis tick values are formatted as label strings. |
VectorCapability | Advertised support for native drawing, without rendering the chart. |
VectorFallback | Policy when a chart declines native SVG/PDF drawing. |
