What if you use r.mapcalc and apply log to your map to make a new one with rescaled values? On Jun 9, 2014 12:36 PM, Veronica Andreo veroand...@gmail.com wrote: Hi list! I have these raster maps of chlorophyll concentration (mg/m3) with a lot of very small values (from 0.02 to 1.5) and few

Yeah, I also tried that, and of course, I get a nice gradient in the legend, but then I need to somehow edit tick-marks. Logarithm of chlorophyll concentration is, from my point of view, uninformative. I need the actual values. I just want to change the display of the legend, like making log of x

Hi list! I have these raster maps of chlorophyll concentration (mg/m3) with a lot of very small values (from 0.02 to 1.5) and few high values (between 20 and 100)... I managed to create my own color table to get a good visualization of the variation... but when I display the legend, i loose the
