PlotArea.InnerHeightRatioToChart

PlotArea.InnerHeightRatioToChart property

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

public double InnerHeightRatioToChart { get; set; }

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() 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().

InnerHeight in Pixel = InnerXRatioToChart * chart.ChartObject.Width.
