Version Lizmap-Web-Client 3.3

Summary

The diagrams you can produce in dataviz tab could be improved. At the moment, we are more at requirements level but we want to discuss how to achieve the result with the community.

Identified requirements

More choice in graphic types using plotly library;
More choice in color scheme;
Possibility to choose the type of value to display inside the graphs (Value, Percentage, round value);
Possibility to choose more than two fields to display inside a same graphic;
Ability to group by any statistics beyond currently available / Ability to create group statistic function (this one is already working, just not well documented);
Possibility to organise/customise legend displaying

Proposed Solution

Switch to use the plugin "Data Plotly" as it enabled at least to solved some of the above requirements and consume the result in Lizmap. This is an early statement. I need to investigate in the code from "Lizmap plugin", "Lizmap Web client" and "Data Plotly" to give a detailed plan to go this way.

Hi, any news on this? Cheers.

In the next version of Lizmap, version 3.4, there are quite a few improvements about the dataviz. You can have now more than one trace on a single plot, there is a dark and light theme etc. So this ticket must be updated first with what have been implemented in LWC 3.4. To try these features, you need the dev version of the Lizmap plugin that you can download here https://packages.3liz.org/pub/lizmap-qgis-plugin/dev/

Great, thanks!

Related to https://github.com/3liz/lizmap-web-client/issues/1907 I think that an integration between lizmap and dataplotly could be very useful.

I dont't have yet any final idea on how to develop this integration, so sharing ideas is more than welcome.

Maybe an additional button in dataplotly (export plot settings for lizmap) could be an initial start point...
