I have a python code (python 3.7) on my power bi desktop file which is working completely fine as you can see from the first image. When i publish it online, the visualization becomes really small and cluttered (without changing anything), as you can see from the second image. How can it be possible? Thanks for you help vicarm
Hy, i have the same problem. did you got any suggestion?
They opened a bug and resolved it last month. I do not experience the problem anymore. The visualization on the web is not as good as on the local version in terms of details but at least it is not cluttered.
Hi @t-vicarm
There are a few constraints on the size of the serialized Python dataframe, and the execution resources used by the Python scripts.
Please check if you meet the limitation.

As i can't reproduce this problem, you may post in Issue forum to report this issue or create a support ticket to get a more quick help.
