Hello Eli, thank you for your lesson! I would sincerely appreciate it if you help me with the following issue: Regarding the coloring of the bars, I typed: plt.figure(figsize = (9 , 8)) plt.bar(x = df_used_cars["Brand"], height = df_used_cars["Cars Listings"], color = "grbgrbgrbb") plt.xticks(rotation = 45) plt.show() However I got the following output and error: ValueError Traceback (most recent call last) ~\AppData\Local\Temp\ipykernel_13440\1396978304.py in <module> 1 plt.figure(figsize = (9 , 8)) ----> 2 plt.bar(x = df_used_cars["Brand"], 3 height = df_used_cars["Cars Listings"], 4 color = "grbgrbgrbb") 5 plt.xticks(rotation = 45) ~\anaconda3\lib\site-packages\matplotlib\pyplot.py in bar(x, height, width, bottom, align, data, **kwargs) 2397 x, height, width=0.8, bottom=None, *, align='center', 2398 data=None, **kwargs): -> 2399 return gca().bar( 2400 x, height, width=width, bottom=bottom, align=align, 2401 **({"data": data} if data is not None else {}), **kwargs) ~\anaconda3\lib\site-packages\matplotlib\__init__.py in inner(ax, data, *args, **kwargs) 1410 def inner(ax, *args, data=None, **kwargs): 1411 if data is None: -> 1412 return func(ax, *map(sanitize_sequence, args), **kwargs) 1413 1414 bound = new_sig.bind(ax, *args, **kwargs) ~\anaconda3\lib\site-packages\matplotlib\axes\_axes.py in bar(self, x, height, width, bottom, align, **kwargs) 2354 linewidth = itertools.cycle(np.atleast_1d(linewidth)) 2355 hatch = itertools.cycle(np.atleast_1d(hatch)) -> 2356 color = itertools.chain(itertools.cycle(mcolors.to_rgba_array(color)), 2357 # Fallback if color == "none". 2358 itertools.repeat('none')) ~\anaconda3\lib\site-packages\matplotlib\colors.py in to_rgba_array(c, alpha) 357 358 if isinstance(c, str): --> 359 raise ValueError("Using a string of single character colors as " 360 "a color sequence is not supported.

Hi Seyed, thanks for reaching out! It seems that the functionality of using a single string as a color has been deprecated in some versions of matplotlib and is no longer supported, that's why you're getting the error. If you'd like to have individual colors for each bar, you can do the following: 1. Have a list of all the colors, using their full names 2. Pass that list for the color argument Here is some example code: colors = ["red","green","blue","white","yellow","magenta","cyan"] plt.bar(x = df_used_cars["Brand"], #specify the x axis height = df_used_cars["Cars Listings"], #specify the y axis color = colors) Let me know if this version works for you or if you have any further questions! Best, 365 Eli
