Hi, I would like to display difference graph of the discontinuous functions. These functions are defined in the same intervals. Could I use XYDifferenceRenderer for this?

5. XYDifferenceRenderer sensitivity    jfree.org

How sensitive is the XYDifferenceRenderer to differences in the domain/x values in two series? I have two series generated which I wish to diff, but because they come from two different runs, the x-values vary slightly. For instance: Series 1: {..., (3601.0, 1.980392), (3702.0, 1.87037), ...} Series 2: {..., (3601.0, 1.980392), (3701.0, 1.886792), ...} In both cases, the '...' are where ...

Hello, I am using an XYDifferenceRender to highlight the difference between 2 time series charts. When the fills are rendered to PNG or SVG, it looks as if the edges of the polygons that are used to fill the differences are showing. Is there any way to override this behavior? Thanks, Dan

8. XYDifferenceRenderer - Invalid memory access of location    jfree.org

I was getting this when using the XYDifferenceRenderer Invalid memory access of location b0e0e6f0 eip=9038fa9b Turns out way back in the server providing our data, there was an occasional divide/zero, which meant the data in my TimeSeries.getYValue was a "NaN" and XYDifferenceRenderer does compares to determine the positive and negative areas. Compares of "NaN"s are always false, so XYDifferenceRenderer could call ...

Bug in XYDifferenceRenderer with inversed domain values by tomkieffer Wed Jan 09, 2008 11:13 am Hi, I created the following demo to demonstrate what I think is a bug in XYDifferenceRenderer. Every thing is ok, if at line 35 the code "inverse(time)" is inactive. If however, as in the demo, I inverse the x-axis values (before creating the dataset), the ...

12. XYDifferenceRenderer + percentage    jfree.org

That is not as easy as you might think. The XYDifferenceRenderer does a lot of interpolating to eliminate the requirement that the two series being diffed share a common set of domain values. This leads to an interesting set of corner cases. Creating a dataset with the values precomputed as percentages will probably work if you do indeed have a common ...
