beta 15 - no plotter…

[Pskalou]

Hello, I want to test the new plotter issue, but I haven't the plotter icon on my menus. Also when i click on the "Acces the file system on the micro:bit", mu stop and exit immediately.

Here is a copy of my log file

thanks for your work. I hope it will be very usefull in classrooms PsKalou

Hi @Pskalou,

Sorry you've been having problems. However, well done you, you've found a bug! ;-)

Out of interest, what version of PyQt do you have installed..? Do you also have PyQCharts installed too..?

The best way to install Mu is by creating a virtualenv and pip installing it in there. Python should download all the necessary things you need. If Mu can't detect the presence of QtCharts it won't display the button for the plotter (thus explaining the first part of your report), and when you click on the "Files" menu, it attempts to turn off the (non-existent) plotter button, thus causing the crash (and hence the kudos to you for finding the bug!).

Fixing this will be very easy and it'll definitely be in the next release of Mu. In the meantime, if you use a virtualenv and pip (pip install mu-editor) then you should get all the required libraries needed for the plotter.

Hope this helps,

N.

Hello @ntoll.

pip install mu-editor

solved immediately the problem. Your command installed on my computer these libraries : mu-editor, pgzero==1.1, matplotlib==2.1.2, pyqt5==5.10, PyQtChart==5.10, qscintilla==2.10.2, pycodestyle==2.3.1 and pygame>=1.9.

Well done to you, and thanks a lot, PsKalou

I'll leave this issue open until I've fixed the bug with the "files" button. :-) It's a good way to track what's going on. Thanks!
