I did enter the program for the ESGraph Plots from your post and initially had an issue when it came to plotting the values.

I think the for loop needs to have the integrals for X,Y vary by the step value defined for T - Basically if you change ∫(A×cos(X^P),0,-2π)→X to ∫(A×cos(X^P),0,T)→X and ∫(A×sin(X^P),0,-2π)→Y to ∫(A×sin(X^P),0,T)→Y I get the graphs shown on your blog.

Apologies if this was obvious to all.

Thanks and regards for making the effort - I do enjoy reading your posts here and on your blog.

It should also be noted that KhiCAS is now available on the Casio Fx-9750GIII (thank you Parisse!) giving it a CAS that is similar to the one in the HP Prime (same Xcas engine).
