Custom scaling function not working

Michal Jex
Posted 3 years ago

I have a problem with the custom scaling of the axes for plots. I need a custom scaling function for both axes but I have found that even a basic example seems not to work as I intend to. Why the next two commands do not produce the same graph? It seems that the function g do not do anything and the function f transforms only y axis.

Plot[{Exp[x]}, {x, 0, 10}, ScalingFunctions -> {"Log", "Log"}, PlotRange -> All]

f[x_] := Log[x]
g[x_] := Log[x]
Plot[{Exp[x]}, {x, 0, 10}, ScalingFunctions -> {f, g},  PlotRange -> All]

Hi Michal,

For custom scaling functions, the inverse function has to be specified as well. Not sure why.

Plot[{Exp[x]}, {x, 0, 10},
 ScalingFunctions -> {{f, InverseFunction[f]}, {g, InverseFunction[g]}},
 PlotRange -> All]

Hello Rohit, thank you for the reply. I checked it and now it works. I would not thought of this.
