Axis

This section is regarding Methods and Properties available in all Axis Elements – axisX, axisY, axisX2 & axisY2.


Example :
    chart.axisX[0].get(“title”);
    chart.axisX[0].convertValueToPixel( 20 );

Note
  • Chart should be rendered before you can access Axis & its methods / properties.

Axis Methods:

convertValueToPixel(Number value) Converts value in axis Scale to Pixel Coordinates chart.axisX[0].convertValueToPixel(20);
convertPixelToValue(Number pixel) Converts given pixel value to axis Scale chart.axisX[0].convertPixelToValue(250);

Read-Only Axis Properties:
