Hi! I'm using QGIS Version 2.18 and I try to change the classification mode via python from "Continuous" to "Equal interval". I found out there is "setClassificationMode" for version 3. Is there anyhow a possibility to change this in version 2.18 ? Mfg Lukas

Hi Nyall, Thanks for your thoughts. And how about going through GDAL/OGR and exporting vector layers twice? One time as raster with styling preserved, and a second time as invisible vector overlays (e.g. fully transparent but still queryable (attributes preserved))? My fear with upstream qt
