Hi i have used improfile to find the intensity of an area over time (over multiple frames actually) and when i plot the intensity profile it looks nice. Now my problem is that i need to scale the plot. I know the size of the area i am looking at and therefore i need to change the x axis to that. Also is it possible to change the intensity to be out of 100% instead of 255 for the y axis? I tried using axis([0 X 0 100]) but that did not work. it shifts the graph to the left. The x distance is reading about 100 pixels and i want that 100th pixel to be X.
Is it possible to do this or does someone suggest another method to find intensity of this object. I hope that was explained clearly.
(The object glows and im tracking the intensity of light if that should matter. I just need to fix that scaling issue and i will be golden.)
