Plotting a hysteresis loop with jFreeChart

Question

I need to draw hysteresis loops and then calculate the area closed within the loop. I am using jFreeChart.

consider the following data:

 hyst[0]=0;
              


        

Answer 1

How can I change the line color as well the symbols representing the data points. I want all of them to be uniform.

It appears you've settled on JFreeChart for your view. Synthesizing a few other comments,

• You can make the colors and shapes of your several series homogeneous by providing a DrawingSupplier, as suggested here and shown here.

• You can combine the series into a GeneralPath and estimate the area as outlined here.
