Create x, y1 and y2 data points using numpy. This results in: Sometimes, you might have two datasets, fit for line plots, but their values are significantly different, making it hard to compare both lines. We can use matplotlib to Plot live data with Matplotlib. Before we dive into creating multiple plots on the same figure, lets first understand some basic concepts of Matplotlib. To increase the size of the figure, we use the figure() method and pass figsize parameter to it with the width and height of the plot. Matplotlib subplot method is a convenience function provided to create more than one plot in a single figure. These observations are made at evenly spaced intervals throughout time. Let's use NumPy to make an exponentially increasing sequence of numbers, and plot it next to another line on the same Axes, linearly: The exponential growth in the exponential_sequence goes out of proportion very fast, and it looks like there's absolutely no difference in the linear_sequence, since it's so minuscule relative to the exponential trend of the other sequence. We use the same data set defined in the above example. 122 would therefore be 1 row, 2 columns, 2nd position. We will look into both the ways one by one. Axes.twiny is available to generate axes that share a y axis but Heres an example: In this example, we create a figure with a 22 grid of subplots and a total size of 86 inches. Here well cover different examples related to the time series plot using matplotlib. We can see that calling `add_subplot()` twice has created a figure with two subplots stacked vertically. As for line type, you need to first specify the color. You can also save the figure (but this must be done before calling plt.plot()) using the plt.savefig() function.
