Non - numeric values for Series Line chart

pankaj_patil20 · Post by **pankaj_patil20** » Thu Sep 21, 2006 6:19 pm

Hi Friends

I am new to the JFreeChart environment.

I am trying to plot a Line chart having 3 series.
If I use numeric values for X axis values, I am good.
eg
XYSeries series1 = new XYSeries("Actual");
series1.add(4.0, 5.0);

The problem arises when I want to use String values for X co-ordinates.

Can anyone help me out on this ?

Thanks in advance

Regards

You have two options:

(1) Use the CategoryPlot class - this is designed for non-numeric x-values;

(2) Keep using XYPlot, but replace the x-axis with a SymbolAxis, and code your dataset accordingly (x values as integer index values).

Hi david,
I recently faced the same problem what pankaj faced.
I have a scatterplot and i want non-numeric values for the x-axis.
I cant use category plot as i have to use XYLineAndShapeRenderer.
Whereas using SymbolAxis makes most of my values disappear.
How to use SymbolAxis for XYPlot correctly?
Thanks in advance.
