1	# DevExpress WinForms Chart Control
2
3	`DevExpress.XtraCharts.ChartControl` is a 2D and 3D data-visualization component that supports 50+ series view types (bar, line, area, pie, financial, radar, polar, funnel, gantt, swift plot for huge datasets, etc.). The architecture is a four-level hierarchy: a `ChartControl` hosts a single `Diagram` of a specific type (`XYDiagram`, `SimpleDiagram`, `GanttDiagram`, `RadarDiagram`, `PolarDiagram`, `SwiftPlotDiagram`, or their 3D counterparts), the diagram contains a collection of `Series`, and each `Series` has a `View` (`BarSeriesView`, `LineSeriesView`, `PieSeriesView`, …) that determines its appearance. The diagram type is implicitly chosen by the first added series' view — adding a `Series` of `ViewType.Pie` produces a `SimpleDiagram` automatically; adding `ViewType.Bar` produces an `XYDiagram`.
4
5	Every chart concept — series, axis, label, legend, tooltip, crosshair, selection — exposes a consistent property model and a `CustomDraw*` event for cases the property model cannot cover. The same `Series` API works for bound and unbound modes: assign `DataSource` + `ArgumentDataMember` + `ValueDataMembers` for data binding, or `Points.Add(new SeriesPoint(...))` for inline values.

7	## When to Use This Skill
8
9	- Adding a chart to a WinForms app — pick a series view, bind data, configure axes.
10	- Choosing the right series view for the data shape (bar comparison vs trend line vs pie share vs financial OHLC vs radar profile vs gantt timeline).
11	- Configuring axes (primary + secondary; Numerical / DateTime / TimeSpan / Qualitative scale types) and their ranges.
12	- Formatting axis titles and labels (`TextPattern` with `{A}`/`{V}`/`{VP}` placeholders + .NET format specifiers).
13	- Aggregating large data sets on a DateTime axis via `ScaleMode = Automatic` and `AggregateFunction`.
14	- Configuring the legend — single or multiple legends, alignment, layout, per-series legend item text via `LegendTextPattern`.
15	- Enabling tooltips and the crosshair cursor; formatting their content; understanding when each one is the default.
16	- Enabling selection (Single, Multiple, or Extended) and choosing whether the entire series, a single point, or all points with the same argument get selected.
