Plt.vlines(x=dates, ymin=0, ymax=10, color = 'r', linewidth=2) In the below example I am using a loop to add texts iteratively to all the vertical lines drawn in the example of the previous topic.ĭates = np.array()Īx.t_major_formatter(mdates.DateFormatter('%d.%m.%y'))Īx.t_major_locator(mdates.YearLocator()) You need to use the text() function from the matplotlib.pyplot where you have to specify the text to be added, and the x and y positions on the X-Y Plane of the plot. You can also add text to the plot at any given position. Matplotlib plot vertical line at the date Matplotlib plot vertical line with text Plt.axhline(y=y_val, color='b', linestyle=':', label='red line') # Plotting the horizontal line to divide through the y_val Plt.bar(x, upper_bars, width=0.5, color='r', bottom=lower_bars) Plt.bar(x, lower_bars, width=0.5, color='y')
Upper_bars = np.maximum(heights - y_val, 0) # we are splitting the heights to create a stacked bar graph by the y_val # y value from where the horizontal line has to be drawn # Define x values and heights for the bar chart In the same way, you can plot a horizontal line on the bar graph. You can plot any type of plot over another plot in matplotlib python by specifying multiple plot statements before saving/displaying the figure. Matplotlib plot horizontal line on bar graph # Plot a simple line chart with neon purple (Hexcode='#B026FF') as line color # Plot a simple line chart with yellow as line color Plt.plot(x, y, 'r', linestyle='-', linewidth=5) # Plot a simple line chart with red as line color Plt.plot(x, y, ':', linewidth=7, color='green') # Plot a simple line chart with green as line color

You can either specify the name of the color or the symbol of it or you can give the hex code of the color enclosed in quotes. There are several colors available in python. You need to specify the parameter color in the plot() function of matplotlib. You can change the line color in a line chart in python using matplotlib. Matplotlib plot line thickness Matplotlib plot line color # Plot a simple line chart with 'dash_dot' linestyle # Plot a simple line chart with 'dotted' linestyle # Or you can use: plt.plot(x, y, linestyle='-') # Plot a simple line chart with 'dashed' linestyle # Plot a simple line chart with 'solid' linestyle
You can search for the available line styles, I have given examples for some commonly used line styles. You can either specify the name of the line style or its symbol enclosed in quotes. There are several line styles available in python. You need to specify the parameter linestyle in the plot() function of matplotlib.
You can change the line style in a line chart in python using matplotlib. Matplotlib plot a line chart Matplotlib plot line style # Plot a simple line chart without any feature So, open up your notebook, not the physical one, open jupyter notebook, and follow the code below: # Importing packages Plot the data by adding the features you want in the plot (plot color, thickness, labels, annotation, etc…).Defining the data values that has to be visualized (Define x and y).Import the required libraries (pyplot from matplotlib for visualization, numpy for data creation and manipulation).You can create a line chart by following the below steps:
Line charts visualize the relationship between two quantities on X-axis and Y-axis on the X-Y cartesian plane. Pyplot provides a collection of related functions for a variety of plots. You can create line charts in python using the pyplot submodule in the matplotlib library. Matplotlib is a cross-platform library built on NumPy arrays. It provides a variety of plots and data visualization tools to create 2D plots from the data in lists or arrays in python. Matplotlib is the widely used data visualization library in Python.
