Dear all,
To submit to a publication with figures in black and white colors, I tried to plot positive and negative anomaly in dark and light gray scale (with white color in centre). I am close to achieving this using a palatte (test.spk), which I defined. However, in the attached figure darkest shade is for next to highest value (between 15-20) but the extreme value (>20) has less darker shade. What I want is progressively darker shade for progressively higher (absolute) values. So I tried to achieve this by adjusting the values/ adding more level etc in the test palette but couldn't succeed. However, If I use only fewer levels (e.g. 7 level) the highest (+ve) level has the darkest shade, but I need to use all the levels shown in the figure. I would appreciate any suggestion on how to achieve the desired shading.
