Hey @winged solar!

It looks like you pasted Python code without syntax highlighting.

Please use syntax highlighting to improve the legibility of your code and make it easier for us to help you.

To do this, use the following method:
```py
print('Hello, world!')
```

This will result in the following:

print('Hello, world!')```
You can **edit your original message** to correct your code block.

winged solar ```import matplotlib.pyplot as plt import psutil as p bg_app_dict = {} count =...

don't capitalise https://matplotlib.org/stable/gallery/color/named_colors.html

winged solar Mar 28, 2024, 1:48 PM

#

sorry what?

#

The line plt.bar(bg_app_list, max_min_bg_app_list, width = 0.5, color = ("Red", "Blue")) keeps giving an error

#

idk why

#

and wdym capitalise?

jade zodiac Mar 28, 2024, 1:51 PM

#

winged solar and wdym capitalise?

I gave you a link to the list of all named colours in matplotlib. You need to use their names exactly as written on that page. For example, 'Red' will give an error, but 'red' or 'r' is a valid colour

I just ran your code and it works fine even with 'Red', hm... what version of matplotlib are you using?

winged solar Mar 28, 2024, 1:55 PM

#

wait is matlplotlib preinstalled in spyder or to be downloaded using anaconda

#

?

jade zodiac Mar 28, 2024, 1:56 PM

#

if I remember correctly, matplotlib is one of spyder's dependencies so it should get installed automatically

winged solar Mar 28, 2024, 1:58 PM

#

oh

#

is there a way to check the matplotlib version then?

jade zodiac Mar 28, 2024, 2:05 PM

#

print(matplotlib.__version__)

winged solar Mar 28, 2024, 2:07 PM

#

my matplotlib version is 3.8.0

#

is that the latest one?

jade zodiac Mar 28, 2024, 2:12 PM

#

no but that shouldn't be an issue, I'm a bit confused why it doesn't work on your machine

#

if you use 'red' do you still get an error?

#

oh you do, I just read the traceback in full

winged solar Mar 28, 2024, 2:20 PM

#

yeah i'm not sure why

#

should i try deleting and redownloading spyder?

#

or maybe some other troubleshooting methods?

#

anyone suggest anything?

modern sky Mar 28, 2024, 3:09 PM

#

have you tried using a float in the second position (replacing blue)? Something like

plt.bar(bg_app_list, max_min_bg_app_list, width = 0.5, color = ("Red", 0.5))

#

the number is for the alpha channel. It wont' solve your problem, but I'm wondering if that works 🤷

#

This is the logic for a tuple when the len is 2 in matplotlib: https://github.com/matplotlib/matplotlib/blob/5e347777192b37ac77decc4f975e53ed9d87973b/lib/matplotlib/colors.py#L321-L325

whole lintelBOT Mar 28, 2024, 3:11 PM

#

lib/matplotlib/colors.py lines 321 to 325

if isinstance(c, tuple) and len(c) == 2:
    if alpha is None:
        c, alpha = c
    else:
        c = c[0]```

modern sky Mar 28, 2024, 3:15 PM

#

The other thing you can maybe try is using the hex values of the colors instead:

# This uses the the red and blue hex values
plt.bar(bg_app_list, max_min_bg_app_list, width = 0.5, color = ("#ff0000", "#0000ff"))
