matplotlib: 3.9.2

this is what i got

I ran the same code, and everything is good.
Can you test different versions of Python and matplotlib and help find the issue?

[winglet0996]

The same issue as @wahaha233333, I didn't see the legend with the code above.

• pycomplexheatmap: 1.7.9
• python: 3.9.20
• matplotlib: 3.9.2

Hi @winglet0996
Thanks for your feedback; it is helpful.
Indeed, there was something wrong with the PyPI 1.7.9. But no problem on the GitHub.
So, I released a new version, 1.8.0. You can either upgrade to 1.8.0 using pip or directly install from github pip uninstall -y PyComplexHeatmap && pip install git+https://github.com/DingWB/PyComplexHeatmap

Please let me know whether it works or not @wahaha233333 @winglet0996

[winglet0996]

That helps! Thanks a lot for your quick reply.

[wahaha233333]

It works!, thank you so much.

I have a related issue I think. I cannot see the bottom of the plots and I need to keep changing the figure size to see the legend using the code in https://dingwb.github.io/PyComplexHeatmap/build/html/notebooks/get_started.html#2.-Plot-heatmap-annotations
code block = [11]

Version 1.8.1.post2
Python 3.12.7
Matplotlib 3.7.5

figsize = 3,4 (exact example code)

increase width (8,4) => can start to see the legend but the image is now scaling as well

[DingWB]

You ran the code in Pycharm or Jupiter?
How can I reproduce this issue?

[mwe-bixeng]

Pycharm equivalent - macOS using venv. I used the codeblock [11] in this example: https://dingwb.github.io/PyComplexHeatmap/build/html/notebooks/get_started.html#2.-Plot-heatmap-annotations
and cannot see the full image + legend.

Version 1.8.1.post2
Python 3.12.7
Matplotlib 3.7.5

What if you save it to a PDF?

[DingWB]

Please try plt.tight_layout() and save to pdf (plt.savefig("example.pdf", bbox_inches='tight')) before plt.show
