Hi Aget,
it depends what you are interested in and how your data are formatted.
ImageJ can do a false-color plot of data in a 2D image such as at the left side.
If your data are some type of image format, just apply a color lookup table (LUT) of your choice, or create your own one with the LUT Editor plugin (I agree with Herbie that the one in your example is not ideal because everything from green via yellow to red will be indistinguishable for almost 10% of the male population in Europe). ImageJ can also do the calibration bar for the color LUT.
You can also have line graphs (Analyze>Plot Profile) for single horizontal lines of the image or averaged over a few adjacent lines (use the rectangular box instead of the line tools). Use Edit>Options>Profile Plot Options for setting line graph options.
For the figure as a whole, the easiest is to save the image and individual line graphs in ImageJ (e.g. as .png) and use a graphics program like LibreOffice Draw to compile everything into a nice figure and write the text.
For reading the data into ImageJ, it is easy if your data are in a text file with one text line per image line or column, and the same number of data points in each line: Use File>Import>Text Image.
For other formats or if each data set is in a file on its own (e.g. 97 files, one for each line), you will have to write a simple macro to read it into ImageJ.
