Using QGIS, QGIS Server, and Lizmap3/3Liz I am trying to make a pie chart that compares attributes but only of the features in the current extent. So when you pan around the webmap the graph changes based on the features in view. I know it can be done in the composer with attribute tables but how can it be accomplished using Lizmap and Dataviz from within the project?
The diagrams feature only works on single features. What I am trying to do is create a chart from the attributes of the features in view with a pie graph nested in a docker to show me, for an example, within the current view how many house holds are there and of those house holds what percentage makes more/less than $xx.xx. As you pan around your statistics will change based on area and how many homes with data are in the extent; and of course if you zoomed all the way out you would gets stats on everything in the view.
