[Qgis-user] Heatmap invbisible

[Junior Delaz]

hi,
can you zoom to the extent of the heatmap layer?
There is a reported (and already fixed for 2.8.2) issue (
http://hub.qgis.org/issues/12264 ) about projection of the "heatmap layer"
and a solution proposed here (
http://gis.stackexchange.com/questions/137770/why-are-heatmaps-on-qgis-2-8-1-produced-in-the-wrong-crs
)
