Research by someHerrings Open source environmental science research at Public Lab Question: What does the vertical scale mean? someHerrings Sun, 22 Nov 2015 00:03:06 +0000 <h3>What I want to do or know</h3> <p>What does the vertical scale actually represent? It seems to be based on the sum of the RGB values. This means that the only way the plot exceeds ~33% is when two adjacent channels have values of 255 which means the source data is too bright.</p> <p>Why not make the 100% level correspond to the maximum level <strong>at that color</strong>? Then a 650nm laser line with an RGB value of (254,0,0) could be represented at 100% instead of around 30%.</p> <h3>Background story</h3>
