I get no plot of anything. I also tried one of Han's examples and get similar results
I have tried both Han's original code as well as the modified code by Cyrille.Are there any General Calculator settings that I might have missed in order for this program to work. When I run the program from the program list, I get the exclamation point inside an orange circle.
What is the correct format for typing in an equation that is going to be displayed?

Did you update your firmware? Both versions rely on commands that exist only in the new firmware. As this is an app, it is not possible to run from the program catalog list. If your firmware is dated as being from August then it is the old one. To check, press the Help key, then the "Tree" menu button. Select About HP Prime and hit "OK"
