If you have multiple sets of bars (like in a grouped or stacked bar plot) you can pass multiple colors via a list or dict. like each column to be colored. We can run boston.DESCRto view explanations for what each feature is. Oftentimes, we might want to plot a Bar Plot horizontally, instead of vertically.

Pandas Bar Plot : bar () Bar Plot is used to represent categorical data in the form of vertical and horizontal bars, where the lengths of these bars are proportional to the values they contain. One axis of the plot shows the specific categories being compared, and the other axis represents a measured value. On top of extensive data processing the need for data reporting is also among the major factors that drive the data world. Allows plotting of one column versus another. column a in green and bars for column b in red. green or yellow, alternatively. ã°ã©ã / æ£ã°ã©ããä¸ã¤ã®ããããã¨ãã¦æç»ããå ´åã¯ä»¥ä¸ã®ããã«ããã.plot ã¡ã½ããã¯ matplotlib.axes.Axes ã¤ã³ã¹ã¿ã³ã¹ãè¿ããããç¶ãããããã®æç»å
