# How to use the same color bar for different DensityPlot [duplicate]

Fixed color scale in multiple density plots

I want to normalize different DensityPlots. The scale for the color bar is from 0 to 1. I can do the job in Origin after I get all the data, but I think Mathematica can do it also. I am not very familar with ColorFunctionScaling--could you show me an example?
