The horizontal line starts at x=4 and ends at x=20.
We have already seen how to create a simple line plot, using numpy to plot a function: hlines and vlines to Plot Horizontal and Vertical Line in Matplotlib Conclusion of Drawing Horizontal and Vertical Lines in Matplotlib In this tutorial, we will introduce two methods to draw horizontal and vertical lines in Matplotlib. These two methods use different coordinates in Matplotlib. axhline() / axvline() hlines() / vlines() 2020-04-12 · The axhline() function in pyplot module of matplotlib library is used to add a horizontal line across the axis. Syntax: matplotlib.pyplot.axhline(y=0, xmin=0, xmax=1, **kwargs) Parameters: This method accept the following parameters that are described below: y: This parameter is an optional and it is position in data coordinates of the horizontal line. import matplotlib. pyplot as plt fig, ax = plt.

Using matplotlib we can implement various types of graphs such as bar graph, pie chart, scatter graph, etc. But we will focus on the line graph for the sake of simplicity. There are also various markers you can use to show lines or points.
Line plots. We have already seen how to create a simple line plot, using numpy to plot a function:

Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. The Axes Class contains most of the figure elements: Axis, Tick, Line2D, Text, Polygon, etc., and sets the coordinate system.
axhline() / axvline() hlines() / vlines() 2020-11-12 · Matplotlib is a popular python library used for plotting, It provides an object-oriented API to render GUI plots. Plotting a horizontal line is fairly simple, Using axhline() The axhline() function in pyplot module of matplotlib library is used to add a horizontal line across the axis. Syntax: matplotlib.pyplot.axhline(y, color, xmin, xmax, linestyle) According to axhline documentation, xmin and xmax should be in the range (0,1). There is no chance that xmax=3.0. Since your intent is to draw horizontal line across the axes (which is the default behavior of axhline method ), you can just omit the xmin and xmax parameter. Share.
Matplotlib is a Python 2D plotting library which produces The basic steps to creating plots with matplotlib are: 1Prepare Draw a horizontal line across axes.
Should be between 0 and 1, 0 being the far left of the plot, 1 the far right of the plot. import matplotlib.pyplot as plt import numpy as np x = np.linspace(1, 21, 200) y = np.exp(-x) fig, ax = plt.subplots() ax.plot(x, y) ax.hlines(y=0.2, xmin=4, xmax=20, linewidth=2, color='r') plt.show() The snippet above will plot a horizontal line in the axes at y=0.2. The horizontal line starts at x=4 and ends at x=20. The generated image is: Dependencies: Matplotlib. The HLine element is a type of annotation that marks a position along the y-axis. Here is an HLine element that marks the mean of a points distributions: For full documentation and the available style and plot options, use hv.help (hv.HLine). Matplotlib has as simple notation to set the colour, line style and marker style using a coded text string, for example "r--" creates a red, dashed line.
