ChartDirector 6.2 (.NET Edition)



[C#] public double getXValue(int xCoor);
[VB] Public Function getXValue(xCoor As Integer) As Double


Gets the x data value given the x pixel coordinate.

This method always returns a numeric value. If the axis scale is a date/time scale, and you are expecting a DateTime data type, please use Chart.NTime to convert the number to the DateTime data type.

Note: This method should be used only after ChartDirector has output the chart image, or after XYChart.layoutAxes, BaseChart.layout or XYChart.packPlotArea has been called. ChartDirector needs to perform auto- scaling and layout the axis before it can convert between pixel coordinates and data values.


xCoor(Mandatory)The x pixel coordinate.

Return Value

The x data value at the x pixel coordinate.
