B4J Question Hansolo Charts - Where do I get the compiled jar files?

Hi,

I am trying to make a custom view spectrogram and saw your post on the Hansolo chats, in particular the heat map.

Hansolo Charts

Hansolo Charts have some very nice looking charts. Download the Jars from the link below and copy the jars into your B4J additional library folder. A sample project is attached ( draws 8x charts). You need to study the code in the classes within the B4J project and then add inline java code and...

I clicked on the file links in this post:

It took me to git hub but there was no jar files for charts-11.2.jar etc, only source code. The latest jar file is charts-21.0.7, this compiles but crashes when run. charts-11.8.jar does work, but no with you other examples.

java.lang.UnsupportedClassVersionError: eu/hansolo/fx/charts/data/DataPoint has been compiled by a more recent version of the Java Runtime (class file version 65.0), this version of the Java Runtime only recognizes class file versions up to 58.0

I haven't a clue on how to build the jar files from the source.


Do you know where I can get the three jar files from?

Best regards
Rob

Hi Johan,

Thanks for that.

I user charts a lot and these ones are particularly good
