expand dataframe viewer
Answered
I work a lot with pandas DataFrame objects in pycharm and visualize them by clicking "view as dataframe" in the debugger.
I've noticed that the table itself doesn't resize with the dataframe window, which makes it so that it's only possible to read a limited number of rows at the time. Is there a way around this? Being able to see the whole table at once would help a lot in many cases

Hi,
Have you tried using Windowed Mode?
yeah, it's in windowed mode for me by default
Hm, that't odd that your data view isn't resized along with window. You have a huge empty space below.
There are also some UI elements missing in the window.
Please try starting with defaults by renaming/removing the following folder (https://intellij-support.jetbrains.com/hc/en-us/articles/206544519):
If doesn't help, please upload your renamed logs folder zipped (Help | Compress Logs and Show in...) to https://uploads.services.jetbrains.com/ and let me know the name of that zip file.
I have the exact same problem as OP for both View As Array and View as DataFrame:
- the data window cannot be expanded vertically and there are no tabs
- also, it seems the Format feature doesn't work for Numpy arrays (for example %.3f has no effect)
- also, DataFrame View doesn't show rows when the new nullable type Int64 is used
I tried to start PyCharm with defaults (removed the config folder), but it didn't help.
Hi Mick,
The issue with Format is known https://youtrack.jetbrains.com/issue/PY-26541, please vote for the ticket and follow it for updates.
The issue with Int64 is also known https://youtrack.jetbrains.com/issue/PY-34650
Unfortunately, they are not addressed yet.
I also found the corresponding issue about table resizing https://youtrack.jetbrains.com/issue/PY-30110
Any news on this issue? I just updated my Pycharm in Mac and I also have the problem too.

I also just got the same problem, and this was just after the latest Pycharm update as of April 2020. Please help, it's almost unusable as it only shows 4 columns :(
I have this problem as well since this week.
The array is showed initially in a small window. Lengthening the window horizontally resizes the visible part of the array accordingly, and shows more values, but lengthening it vertically doesn't. The visible part of the array is fixed to 4,5 rows

@Grantyfang
The bug should be fixed in that version. Could you file a separate issue to https://youtrack.jetbrains.com/issues/PY and provide steps for reproducing along with information about your environment (OS, Python version, packages version)?
