PlotArea.YRatioToChart

PlotArea.YRatioToChart property

Gets or gets the y coordinate of the upper top corner of plot-area bounding box in units of ratio of the chart area.

public override double YRatioToChart { 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().

YPixel = YRatioToChart * chart.ChartObject.Width.
