# rpptx-chart
ChartML modeling, editing, workbook integration, validation, and backend-neutral chart geometry.
## Use it when
Use this crate when implementing editable OOXML charts or rendering chart geometry. Use `rpptx` for charts inside a complete presentation.
## Relationship
It uses SpreadsheetML workbooks from `oxml-sml` and feeds chart geometry into presentation rendering.
## Example
```rust,no_run
use rpptx_chart::AxisId;
let category_axis = AxisId::new(10_000_001)?;
let value_axis = AxisId::new(10_000_002)?;
assert_ne!(category_axis, value_axis);
# Ok::<(), rpptx_chart::ChartError>(())
```
Add `rpptx-chart = "0.2.0"` to your dependencies. See the [chart API](https://docs.rs/rpptx-chart) for supported plot families.
