Lets do a simple example to understand the concept clearly. In this example, we will learn how to draw a vertical line with the help of matplotlib. You can specify the color parameter as a positional argument (eg., c > means cyan color; y > means yellow color) or as keyword argument (eg., color=r > means red color; color=green; color=#B026FF > means neon purple color). 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. Another simple way is to use the pandas.DataFrame.pivot function to format the data. Count n finds, number of color lines has to be plotted.

Create x for data points using numpy. 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. Matplotlib Server Side Programming Programming. Matplotlib is a multi-platform data visualization library built on NumPy arrays and designed to work with the broader SciPy stack. top of the orange rectangle.

Use pandas.DataFrame.plot to plot. To plot multiple line plots in Matplotlib, you simply repeatedly call the plot() function, which will apply the changes to the same Figure object: Without setting any customization flags, the default colormap will apply, drawing both line plots on the same Figure object, and adjusting the color to differentiate between them: Now, let's generate some random sequences using NumPy, and customize the line plots a tiny bit by setting a specific color for each, and labeling them: We don't have to supply the X-axis values to a line plot, in which case, the values from 0..n will be applied, where n is the last element in the data you're plotting. The first way is when we want to add a single or main title to the plots or subplots, then we use suptitle() function of pyplot module. Here we will use two lists as data for two dimensions (x and y) and at last plot the line. Plot a Point or a Line on an Image with Matplotlib.
