Problem Description

So no plots show up in version 6.0.0b2.

What steps reproduce the problem?

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt

# Generate 1 million random datetimes using pandas
start_time = '2020-01-01 00:00:00'
datetime_range = pd.date_range(start=start_time, periods=1_000_000, freq='min')

# Generate 1 million random floats
random_floats = np.random.random(1_000_000)

# Sort the random floats
sorted_random_floats = np.sort(random_floats)

# Create Polars DataFrame
df = pd.DataFrame({
    'datetime': datetime_range,
    'sorted_random_floats': sorted_random_floats
})

# Plot the first 1000 sorted random float values against their datetime values
plt.figure(figsize=(10, 6))
plt.plot(df['datetime'][:1000], df['sorted_random_floats'][:1000])
plt.xlabel('Datetime')
plt.ylabel('Sorted Random Floats')
plt.title('Sorted Random Float Values Over Time')
plt.xticks(rotation=45)
plt.tight_layout()
plt.show()

What is the expected output?

That i can see plots

[ccordoba12]

Hey @Chuck321123, thanks for reporting. What do you mean by this?

So no plots show up in version 6.0.0b2.

What's exactly happening in your case? Is the Plots pane not visible? Or are plots not being shown in the IPython console?

[Chuck321123]

@ccordoba12 Plots are not showing up in the plot panel

[ccordoba12]

Ok, and are you able to create plots outside Spyder?

[Chuck321123]

@ccordoba12 Yes

[victorsanchezarevalo]

I have the same problem

[victorsanchezarevalo]

Ok, and are you able to create plots outside Spyder?

I have been able to do it in Visual Studio Code

[victorsanchezarevalo]

I have solved the problem with ploty using, import plotly.io as pio pio.renderers.default = "png" but I cannot see the graph with matplotlib

[victorsanchezarevalo]

In a different computer I see the plots with ploty and matplotlib

[victorsanchezarevalo]

I have change the conda enviroment and now I see the plots perfectly.

[ccordoba12]

@Chuck321123, please post the output of conda list for the environment in which you have beta2 installed. That will help us to reproduce your problem on our side.

[victorsanchezarevalo]

After changing the conda environment, it seemed to work, but again I am having problems plotting with matplotlib. Plotly works perfectly. I also had problems plotting survival curves with lifelines.

[Chuck321123]

@ccordoba12 Sure:

@Chuck321123, are you still having this issue in 6.0 beta3?

[victorsanchezarevalo]

@Chuck321123, are you still having this issue in 6.0 beta3?

I still have the same problem with 6.0 beta3

[tlstevenson]

I wonder if this is related to the latest issue of plots not showing when using external python environments: #22420

[tflidd]

I have python 3.10.7, and I had the same symptoms after updating to spyder 6. In other software, matplotlib still worked. I updated a number of potentially related packages (everything with qt5). In the end I updated IPython from 8.22.1 to 8.27.0 and now it works again.

Downgrading IPython to 8.22.1 breaks it again.

[tlstevenson]

I updated a number of potentially related packages (everything with qt5)

Could you share what else you updated or share your conda enviroment packages & versions? I tried updating just IPython in a basic conda environment (with matplotlib and spyder-kernels 3.10) and I still couldn't get plots to show

[tflidd]

I updated some upfront: matplotllib 3.9.2, pandas 2.2.2, numpy 1.26.4, and spyder 6.0.0. It's a native python environment and everything installed with pip (no additional package manager).

This is when I ran into problems, and I updated these on top:

I still have the same problem, It does not work.

I updated matplotlib-inline from 0.1.6 to 0.1.7, and it broke again. Reverting back to 0.1.6 makes it work again. A bit strange, people here with problems seem to use 0.1.6.

However, using IPython directly, both versions work with:

import matplotlib.pyplot as plt
%matplotlib qt5
plt.plot([0, 1, 2])

In spyder I get this error:

%matplotlib qt5
Warning: Cannot change to a different GUI toolkit: qt5. Using qt instead.
Traceback (most recent call last):

ValueError: supported formats are: 'jpg','svg','jpeg','png2x','png','retina','pdf' not 'g','p','n'

it is the same if I use qt instead of qt5.
No idea if this helps, or just adds to the confusion.

Interesting! I just solved my issue by upgrading matplotlib-inline from 0.1.6 to 0.1.7

Hi folks, we found the cause of this problem: a mix of incompatible Matplotlib and Matplotlib-inline versions, possibly with IPython in the mix too, as you found out.

Please continue the discussion on that issue. I'm going to close this one to consolidate everything in a single place.
