I am using QGIS Essen on Windows 10. I have a data set (.txt file) that contains latitude, longitude, and black carbon (BC) values. I can style the layer using the values of BC - graduated style, color ramp. As such:
However, I would like to have the colors in log scale so I can still distinguish between the different low values (yellow dots). As you can see on the right side, all is just yellow. Is there a way to do this?
Update: I tried again the field calculator approach and got a nice plot. However, I would like the color ramp "logged" and not the values (please let me know if this makes sense). I'm trying to achieve something like this that I have done in Igor (but the graphics is better in QGIS):
As you can see, the color scale is also logged. Is this possible in QGIS?
