# Charts

addChart(): column, bar, line, pie, doughnut, radar and scatter, with axes and labels.

```csharp
using NetCorePpt;                  // PptxGen, Slide
using NetCorePpt.CoreInterfaces;   // option objects: TextProps* / ShapeProps / ImageProps / TableProps / HAlign / VAlign ...
using NetCorePpt.CoreEnums;        // ShapeType, ChartType, MediaType, ShadowType, BulletType, DashType, SCHEME_COLORS ...
using TableRow = System.Collections.Generic.List<NetCorePpt.CoreInterfaces.TableCell>;

### Core Chart Types

- Chart type can be any one of `pptx.ChartType`
- Currently: `pptx.ChartType.area`, `pptx.ChartType.bar`, `pptx.ChartType.bar3d`, `pptx.ChartType.bubble`, `pptx.ChartType.bubble3d`, `pptx.ChartType.doughnut`, `pptx.ChartType.line`, `pptx.ChartType.pie`, `pptx.ChartType.radar`, `pptx.ChartType.scatter`

### Combo Charts

- Chart types can be any one of `pptx.ChartType`, although `pptx.ChartType.area`, `pptx.ChartType.bar`, and `pptx.ChartType.line` will give the best results.
- There should be at least two chart-types. There should always be two value axes and category axes.
- Combo charts have a different function signature than standard. There are two parameters:
  - `chartTypes`: Array of objects, each with `type`, `data`, and `options` objects.
  - `options`: Standard options as used with single charts. Can include axes options.
- Columns makes the most sense in general. Line charts cannot be rotated to match up with horizontal bars (a PowerPoint limitation).
- Can optionally have a secondary value axis.
- If there is secondary value axis, a secondary category axis is required in order to render, but currently always uses the primary labels. It is recommended to use `catAxisHidden: true` on the secondary category axis.
- Standard options are used, and the chart-type-options are mixed in to each.

### Usage Notes

- Zero values can be hidden using Microsoft formatting specs
- Use `*LabelFormatCode` props to format numbers — see [Microsoft Number Format Codes](https://support.office.com/en-us/article/Number-format-codes-5026bbd6-04bc-48cd-bf33-80f18b4eae68)
