To understand the concept more clearly, lets see different examples: In this example, we draw three multiple lines plots. You can also plot more than one line on the same chart/graph using matplotlib in python. However, we can also use this function for creating multiple graphs simply by adjusting the parameters. Overall trend and difference between the days (colors) being the most important things to note and also the easiest to visualize (for the trend you just observe the distribution of the lines. You can plot multiple lines showing trends of different parameters in a time series data in python using matplotlib. You can use the new defaults on a per axes object ratio, or you can install temporarily the new default. In our earlier article, we saw how we could use Matplotlib to plot a simple line to connect between points. Providing the colors in the 'color' column exist in matplotlib: List of named colors, they can be passed to the color parameter. We will look into both the ways one by one.

There are some cases where the values of different data to be plotted on the same graph differ hugely and the line with smaller data values doesnt show its actual trend as the graph sets the scale of the bigger data. 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. The top row of Plot lines with x and y (x+i/20) using plot () method, with marker=o, linewidth=7 and colors [i] where i is the index. To define x and y data coordinates, use the range () function of python. In combination, Create a list of colors (rainbow VIBGYOR). To build a line plot, first import Matplotlib. For example, if line_1 had an exponentially increasing sequence of numbers, while line_2 had a linearly increasing sequence - surely and quickly enough, line_1 would have values so much larger than line_2, that the latter fades out of view. 95 out of the 148 X11/CSS4 color names also appear in the xkcd color survey.
