JFreeChart always puts the axes at the edges of the chart, regardless of the position of the zero value.

Hi any one found how to customize coordinates of x-axis to start from 0 position of Y-axis.

2
1
0 ________1 2 3 ___________________________________________________________
-4 ____________X-Axis Scale______________-

What you probably want is to set the range of the data, not the axis. The axis is the component that displays the labels and the ticks with information about the charted data.

The axis object contains methods to decide whether the chart will be adjusted to all the data or other limits are going to be set. For example, you may want to use the method setRange(minValue, maxValue) of the ValueAxis of your plot.
