Update to latest JFreeChart 1.5.3 and update code? Missing BarRenderer3d

[tmulle]

Hi,

Thanks for this code, we would like to use this in our project but can't because of the use of a very old JFreeChart version as the dependency in this project.

We use the latest 1.5.3 version and after trying to exclude the 1.0 version in this project things compile but the code fails with a ClassNotFound on BarRenderer3D.

After searching the JFree.org javadocs looks like this class is no longer supported.

Would you be able to update the project?

I found this link on the 1.5 version and the changes to the 3D libraries:

I just deployed a new version of JSparklines (v1.1.0) which updates jfreechart to version 1.5.3. Note that Java 11 or newer is now required.

Hopefully this will enable you to use JSparklines in your project?

Thanks for the update! Funny enough, I cloned your repo and made the same exact changes you did before I heard back from you. We are evaluating the use of the project in ours as a proof of concept. Question, do you have any renderers that provide something like MIN/MID/MAX range? We’d like to display 3 colors based on a MIN, MID and MAX value in the Bar Chart Renderer. So, if any number is at the MIN or below we could assign RED color, for example Anything from MIN -> MID is yellow Anything from MID->MAX+ is GREEN We are trying to model Signal (DB) numbers in our table. I looked at the provided renderers and didn’t see anything like I mention, of course I might have missed something. Thanks!

I think the closest you get is the gradient color coding (no.uib.jsparklines.renderers.util.GradientColorCoding).

Example:
((JSparklinesBarChartTableCellRenderer) singleValuesJTable.getColumn("Peptides").getCellRenderer()).setGradientColoring(ColorGradient.BlueWhiteGreen, false);

The input here is only min and max for the given column though, and the colors are graded from, in the case of the above example, blue to green with white in the middle.

But it should perhaps be possible to extend this class to also support your simpler three-color scheme?
