I've done a fair bit of searching, but cannot find anything on this.
When I export an SRTM dataset as a Geotiff from Global Mapper and bring it into QGIS 3.18.1 I need to place a colour legend bar. The legend in GM is fine (see below) but of course when I bring it into QGIS it comes in as a 3 band raster. Placing a legend in the QGIS print layout results in a legend for each band.
Is there a way to get a combined colour bar in QGIS? I'm not happy with any of the colour palettes available in QGIS if I bring it in as a single band.
