Sure! It is not an extremely "tough" case, but it really makes a difference between using a calculator from the 2000's and the HP Prime. I enclose the application that creates the set of equations to draw a Smith Chart. The app is a proof of concept to explain these graphs in RF engineering lessons (in fact, using RE() and IM() in the equations is more effective, but that's out of the scope of this thread).

The app can create three sets of 10 parametric expressions to test the graphing performance. Each set can be chosen with the View button. A default set is created when starting the app.
To reproduce the sporadic decrease in the graphing speed:
1) start the app,
2) check the equations are available at Symb view,
3) plot them,
4) repeat steps 2) and 3) several times

Me, after about 16 repetitions of steps 2)-3) in the HP Prime G2, the graphing speed started to decrease.

There are also 3 available sets of equations that can be played with, available with the View button:
1) Chart
2) ChartEXP
3) ChartIFTE

Equation set 1) is the default and requires computing more points than set 2). It is possible to switch between sets with the View button and check the effects in the plotting speed.

Keep on working with the HP Prime! I expect to use it in this new course to support some explanations in telecomm. engineering lessons.
