[pstricks] \psxTick(){} and \psyTick(){}

[Hubert Lam]

Hi all

Has there been anyone who could tame \psxTick and \psyTick to accept some PS commands?

Say for example I wish to place a y-tick at $\frac{\pi}{2}$. At the moment it seems that I have to use a decimal approximation:

\psyTick(1.57){\frac{\pi}{2}}

But it would be terrific if it could be modified to accept some PS calculatios:

\psyTick(!PI 2 div){\frac{\pi}{2}}

Similarly with fractions, if I want to place an x-tick at $\frac{110}{1230}$ then I would have to use

\psxTick(0.08943089){\frac{110}{1230}}

...whereas it would be terrific if it could accept

\psxTick(!110 1230 div){\frac{11}{1230}}

(Or am I not using it properly?)

Many thanks!
