Skip to main content Crate oxml_chart Copy item path Source Axis The common modelled sequence of one ChartML axis. AxisId A producer-compatible ChartML axis identifier. CT_Chart The implemented behavior-bearing core of one c:chart. CT_ChartSpace One complete c:chartSpace part with the F-118 core typed. CT_DLbls Collection-level data-label defaults for one chart series or plot. CT_Legend A legend retaining opaque children and their effective projection. CT_PlotArea A plot-area shell. F-119 through F-122 replace selected raw slots with types. CT_Title A chart title with plain-text authoring and preserved unsupported children. ChartData Data used to author one chart and its editable workbook. ChartGeometry Backend-neutral plot geometry and the plot rectangle reserved inside a chart. ChartLines Shape properties on a major or minor gridline container. LegendSettings Effective legend settings. An absent legend has right/false defaults. NumberFormat Number format applied to axis values and labels. NumericData A formula-backed numeric cache whose metadata and points are derived. RgbColor A validated DrawingML sRGB colour. Scaling The modelled values of c:scaling. Series The common formula-backed payload of one ChartML series. StringRef A formula-backed string cache whose count and point indexes are derived. AxisData AxisKind The concrete ChartML root used by an axis. AxisPosition Which side of the plot area carries an axis. BarDirection Whether bars extend along the category or value axis. BarGrouping Grouping modes supported by a two-dimensional bar plot. ChartError Errors produced while reading or writing the implemented ChartML core. ChartKind One supported two-dimensional chart family. DataLabelPosition Placement of a chart data label relative to its data point. DispBlanksAs How a chart displays cells whose cached values are blank. Grouping Grouping modes shared by line and later area plots. LegendPosition The five ChartML legend positions. Orientation Direction of values along an axis scale. Plot A supported two-dimensional plot owned by one plot area. RadarStyle Display style for a two-dimensional radar plot. ScatterStyle Display style for a two-dimensional scatter plot. TickLabelPosition Placement of tick labels relative to an axis. TickMark Placement of a major or minor tick relative to its axis line. A_NS The DrawingML namespace written on a chart-space root. C_NS The transitional ChartML namespace used by OOXML packages. C_PREFIX The fixed ChartML prefix used by writers in this crate. R_NS The office-document relationships namespace written on a chart-space root. authored_chart_parts Authors one ChartML part and its editable workbook from one validated source. chart_legend_settings Read only the namespace-owned legend without rewriting producer bytes. chart_workbook_relationship_id Resolve only the root-owned ChartML externalData relationships attribute. read_chart_data Project one supported chart family and its cached data without changing source.
Sparse numeric cache entries remain NaN, and sparse labels remain empty.
Unsupported plots and incompatible category vectors return contextual errors. read_chart_type Reads a bounded XL_CHART_TYPE value from one owned ChartML plot.
Valid unsupported or combination plots return None. Reading does not project
dense caches, resolve an embedded workbook, or rewrite retained source. render_chart Converts one supported typed chart into a labelled backend-neutral group. render_chart_placeholder Shapes the stable label used inside a visible unsupported-chart fallback. render_geometry Converts one supported typed chart into chart-local backend-neutral paths. replace_chart_data Stage replacement chart caches and only their formula-owned workbook cells.
The caller publishes both returned parts together after proving package owners.
Original root, plot, axes, legend and surviving series formatting stay exact. set_chart_legend Stage a legend edit, preserving all other source bytes. None leaves a property unchanged.
Position and overlay edits of an absent legend are no-ops. Hiding drops its settings. Result
