I have some output from a complex relation , the 4 variable are in coloumns as x,y,z, and m and I need a 4D data surface plot,( not using scatter3 ) the data are as given below

Actually I need continues relationship among them instead of scattered relationship

I can plot the surface plot for x,y,z but can not introduce m, the 4th variable as colour bar; please check the code
