Line chart problem

[emesol]

  I'm using jFreeChart in JasperReports (iReport). I'm creating a line chart with more than one series, but the problem i'm facing is that the first line drwan in the results puts its starting point right in the middle of the graph, and then each new result is appended and the line gets wider and expands to the lesft and the right at the same time, I'm wondering if the starting point in the graph can be at the far left and then increments to the right? (like a progressing points going from left to right)

I'm using a customizer class and I have access to the jFreeChart object

Attached is a screen shot of the problem.

Thanks all!
