To plot a multicolored line based on a condition in Python Matplotlib, we can take the following steps Set the figure size and adjust the padding between and around the subplots. label ('color') and a sequence of valid color denominations. Line styles and colors are combined in a single format string, as in 'bo' for blue circles. 6 Answers Sorted by: 106 Another simple way is to use the pandas.DataFrame.pivot function to format the data. If we plot it on a logarithmic scale, and the linear_sequence just increases by the same constant, we'll have two overlapping lines and we will only be able to see the one plotted after the first.
