[Geoserver-users] Chart extension

Hi all

I am looking for a GeoServer symbolizer to produce scaled pie charts.

When I search for Geoserver chart, the first result I get is https://geoserver.geo-solutions.it/edu/en/pretty_maps/charting.html It refers to Eastwood Charts, which appears to be a project last touched 12 years ago. Is this the code used by the official extension: Chart Symbolizer or is it now included inside GeoServer? Is this extension actively maintained?

Is this the preferred charting solution? I see it referenced in a number of SO answers.

The other thing that confuses me is that while this extension appears in http://geoserver.org/release/stable/ , it is not listed at https://docs.geoserver.org/stable/en/user/extensions/index.html but that list says that it is not exhaustive.

Andrea/GeoSolutions, would it be acceptable to add a link to the extensions page above linking to your website, or would it be better to copy that charting.html page into the GeoServer documentation? If so, I could do it with your permission.

Thank you

Peter

Hello Peter,

How do you plan to deliver the map ? If you use OpenLayers, you can perhaps try to use the chart style provided by ol-ext (https://viglino.github.io/ol-ext/).

Thanks Alexandre. I have considered OpenLayers, or preferably Leaflet, but the intension is to render it in GeoServer (to protect the raw data) unless there are very definite reasons not to use the Chart extension.

Regards

Peter

The project seems to be a bit more active then that, just ignoring their old website https://github.com/jfree/jfreechart

It would be good to update to a newer version if you have funding / interest.

I would just say that I recently installed and used the chart extension for pie charts and found it worked well whatever the age of the code. I got the extenson from

http://sourceforge.net/projects/geoserver/files/GeoServer/2.15.0/extensions/geoserver-2.15.0-charts-plugin.zip

but obviously you would need to get for your version of geoserver.
