Matplotlibspyplot API has a convenience function called subplots() which acts as a utility wrapper and helps in creating common layouts of subplots. """ import matplotlib.pyplot as plt import numpy as np # Simple data to display in various forms x = np. For very refined tuning of subplot creation, you can still use add_subplot() directly on a new figure. Look at this example to see how easy it really is. This function creates a figure and a grid of subplots with a single call, while providing reasonable control over how the individual plots are created. The anatomy of a Matplotlib plot: what is a subplot What are the Axes What exactly is a figure. 25) for i in range(rows*columns): exec (f"plt.subplot(grid”)."""Examples illustrating the use of plt.subplots(). #SUBPLOT MATPLOTLIB EXAMPLE CODE#For example, if you want to create Figure 6 (two rows and 4 columns) with gridspec, you can use this code import matplotlib.pyplot as plt fig = plt.figure(figsize=(16, 6)) rows = 2 columns = 4 grid = plt.GridSpec(rows, columns, wspace =. Create simple axes in a figure with gridspecĪs I mentioned before, besides using subplot to create some axes in a figure, you can also use gridspec. After that, create the subplot using the same procedure with the previous code, but place it in looping syntax. We use the second syntax for subplot(), where the number of rows. , 248 for i in range(len(coord)): plt.subplot(coord) plt.annotate('subplot ' + str(coord), xy = (0.5, 0.5), va = 'center', ha = 'center')īecause you want to create 8 axes (2 rows and 4 columns), so you need to make an array from 241 to 248. The details will be presented as two subplots in a single figure. , 248 for i in range(1, 9): # in python, 9 is not included row = 2 column = 4 coord.append(str(row)+str(column)+str(i)) # create subplot 241, 242, 243. You can reproduce Figure 6 using this code fig = plt.figure(figsize=(16, 6)) coord = # create coord array from 241, 242, 243. Create a simple subplot using looping in Matplotlib (Image by Author). You can use this code to generate it fig = plt.figure(figsize=(12, 4)) coord1 = 121 coord2 = 122 plt.subplot(coord1) plt.annotate('subplot ' + str(coord1), xy = (0.5, 0.5), va = 'center', ha = 'center') plt.subplot(coord2) plt.annotate('subplot ' + str(coord2), xy = (0.5, 0.5), va = 'center', ha = 'center')įigure 6. Next step is creating two horizontal axes in a figure, as shown in Figure 4. You also can generate Figure 3 without subplot syntax because you only generate one axes in a figure. Because you only have one row and one column (it means you only have one cell), your axes are the main figure. You may also want to check out all available functions/classes of the module matplotlib.pyplot, or try the search function. coord 111 means, you generate a figure that consists of one row, one column, and you insert the subplot in the first sequence axes. and go to the original project or source file by following the links above each example. It consists of three numbers representing the number of rows, columns, and the axes’ sequence. The variable coord in the code above is 111. import matplotlib.pyplot as plt import numpy as. One of the important things to understand the subplot in Matplotlib is defining the coordinate of the axes. For very refined tuning of subplot creation, you can still use addsubplot() directly on a new figure. You can generate Figure 3 using the following code import matplotlib.pyplot as plt fig = plt.figure() coord = 111 plt.subplot(coord) plt.annotate('subplot ' + str(coord), xy = (0.5, 0.5), va = 'center', ha = 'center') A simple subplot in Matplotlib (Image by Author). ![]()
