Easy Bugs

[PANAMATIK]

It is normally more easy to fix a bug which is reproducible by just a few key clicks, compared to other bugs, which appear only in special contexts. I think I found an easy reproducible bug, which shows a total crash:

Enter in Statistics 1Var Symbolic View H1: 'MinVal' Enter, or any other 1Var App Results Variable from the Vars menu, then press Plot. The application crashes, the screen gets dark, and HP Prime will restart. All previously entered statistics Data D0-D9 is lost.

I think this application is very easy to use and has some powerful functions. It is not mentioned in the manual that you can enter for H1-5 also a List Variable L0-L9, which is a good idea. However you can also enter a single number, like 3.14, in this case the frequency is not updated, it is still the number of elements of the previously used List variable. After trying to enter any number into Frequency, I get the error message 'unsufficient data'.

In my opinion 1Var Statistics is a very good statistics implementation for a calculator, it is easy to use and shows all needed values very elegant. I dont have experience with other graphic calculators. So I hope this opinion is correct.

When using Autoscale with Histogramm type, it happened to me that I got the error message 'Only one Y value found' , because H Range was outside of the data range. I needed some time to find out this reason. Couldn't autoscale set H Range automatically? This appears to me more comfortable, if possible.
