Hi James,

 

Thanks a lot for your information, also I want to ask you if you have a method or a threshold to define the numbers of coordinates necessary to create the polygon. I mean, for an specific area why to use 100 geographical coordinatesand not 1000.

 

Thanks in advance jamesdales

Hi Edwardo

 

I would always suggest to use the minimum amount of coordinates possible, as the fewer you use, the faster performance will be. There will always be a compromise between showing enough detail vs speed. It's the same with the Power BI shape map.

 

Also you'll hit the maximum length of a field in PowerQuery which is 32,766 characters, so beyond that you'll need to split the WKT shapes and then concatenate them using DAX in the data model.

    Hello James,

       Is there a maximum number of points to graph the icons, that is, the number of rows has a limit?

Thank you so much jamesdales 
Regards,
    Nicolas

      There is a limit of 30,000 rows, however I would caution trying to draw 30,000 complex polygons, or 30,000 images as performance will suffer. 30,000 circles however should be fine.

        Hi jamesdales , improvements are amazing first of all.

         

        I have a minor suggestion regarding drilldown experience. If left click drilldown mode is enabled by user and user is at max detail level in hiarercy, left-click on data points may filter selected data point instead of doing nothing. Therefore end user won't need to switch drilldown mode to filter data at final level.

         

        Thanks,
