I have used the DensityPLot to show two functions $f_1$ and $f_2$ in different regions. I want to combine them using the Show function. The problem is, the colors are not consistent in the two different plots. For example, regions where the magnitude of the function $f_1$ is equal to one is shown by red, while regions where the magnitude of the function $f_2$ is equal to one is shown by blue. How can I solve this issue?

    $\begingroup$ You should set the scaling manually in both plots. It can be done by specifying ColorFunction -> ColorData[{"TemperatureMap", {min, max}}] where min and max are the endpoints of your domain. $\endgroup$

  • $\begingroup$ It doesn't work. @C.E. and still shows different colors for the same values in different plots $\endgroup$

    $\begingroup$ You might want to leverage ColorFunctionScaling -> False with some manual plot-range and scaling controls. $\endgroup$
