Transform axis value to pixel value and vice-versa

SfCartesianChart offers two utility methods to transform the pixel into a chart point and vice-versa.

• ValueToPoint(ChartAxis axis,double value) - Converts the data point value to the screen point.
• PointToValue(ChartAxis axis,double x, double y) - Converts the screen point to the chart value.

C#

if (chart is SfCartesianChart cartesianChart)
{
    //Convert screen point to chart point.
    var xValue = cartesianChart.PointToValue(cartesianChart.XAxes[0], pointX, pointY);
    var yValue = cartesianChart.PointToValue(cartesianChart.YAxes[0], pointX, pointY);

    //Convert chart point to screen point.
    var xPoint = cartesianChart.ValueToPoint(cartesianChart.XAxes[0], xValue);
    var yPoint = cartesianChart.ValueToPoint(cartesianChart.YAxes[0], yValue);
}
