## PlotArea::GetInnerWidthRatioToChart method


Gets or sets the width of the plot area in units of the ratio of the chart area.

```cpp
double Aspose::Cells::Charts::PlotArea::GetInnerWidthRatioToChart()
```

## Remarks


The plot-area bounding box includes the plot area, tick marks(tick labels), and a small border around the tick marks. If the value is not created by MS Excel, please call [Chart.Calculate()](../../chart/calculate/) method before calling this method. 

The **XRatioToChart**, **YRatioToChart**, **WidthRatioToChart** and **HeightRatioToChart** of **[PlotArea](../)** represents the plot-area bounding box that includes the plot area, tick marks(tick labels), and a small border around the tick marks. If you want to get actual size of plot area, you should call **InnerXRatioToChart**, **InnerYRatioToChart**, **InnerWidthRatioToChart** and **InnerHeightRatioToChart** properties.

For excel 2007 or latter, the default value is zero. you should call get the value after calling [Chart.Calculate()](../../chart/calculate/).

InnerWidth in Pixel = InnerXRatioToChart * chart.ChartObject.Width. Note: When InnerWidthRatioToChart is set, the IsInnerMode property will be automatically set to True.
