[@danieleoxoli7664]

Thanks a lot for providing this on behalf of the plugin authors!

[@Serbinnhio]

Just followed your instructions and finally got the Hotspot analysis tool to work. The python related stuff was what I had trouble with. Thank you!

The same problem happened to me as well. I am still in search of the solution.

[@xuewenlu3785]

Same issues. Have you found a solution ？

[@marceloamorimtolentino3741]

Thank You! Great Job. I gotta a question: Is it possible to make a heatmap to map the drainage density using polylines in Qgis? I didn't find anything by now.
