I Initialize the cursor Tool:

cursorTool = new CursorTool(this.getChart());
cursorTool.setActive(false);
cursorTool.setFollowMouse(true);
cursorTool.setStyle(CursorToolStyle.VERTICAL);
cursorTool.getPen().setStyle(DashStyle.SOLID);

When the user clicks on the graph (mouseClicked MouseEvent), then I enable the cursor tool:

Code: Select all

if(!cursorTool.getActive())
{
      cursorTool.setXValue(e.getX());   
      cursorTool.setActive(true);         
}

The issue that I'm having is that the vertical cursor line does not appear when the user clicks on the chart, but only after the user moves the mouse. Is there any way that the vertical line can show up upon a mouse click instead of a mouse movement once it's enabled?

Thanks

Hello Turc,

Not the MouseEvent gives you the Mouse pointer position in pixels, through the getX()/getY() functions, while the CursorTool setXValue() function expects to receive a Value on the axis scale as a parameter.
So you gave to convert the e.getX() value to the Axis scale. This seems to work fine for me here:

Code: Select all

cursorTool.setXValue(tChart1.getAxes().getBottom().calcPosPoint(e.getX()));
