You can use the following syntax to set the x-axis values for a plot in Matplotlib:

#specify x-axis locations x_ticks = [2, 4, 6, 8, 10] #specify x-axis labels x_labels = ['A', 'B', 'C', 'D', 'E'] #add x-axis values to plot plt.xticks(ticks=x_ticks, labels=x_labels)

The following examples show how to use this syntax in practice.

**Example 1: Set X-Axis Values at Equal Intervals**

The following code shows how to set the x-axis values at equal intervals in Matplotlib:

import matplotlib.pyplot as plt #define x and y x = [1, 4, 10] y = [5, 11, 27] #create plot of x and y plt.plot(x, y) #specify x-axis locations x_ticks = [2, 4, 6, 8, 10] #specify x-axis labels x_labels = ['A', 'B', 'C', 'D', 'E'] #add x-axis values to plot plt.xticks(ticks=x_ticks, labels=x_labels)

Notice that each x-axis value appears at equally spaced intervals.

**Example 2: Set X-Axis Values at Unequal Intervals**

The following code shows how to set the x-axis values at unequal intervals in Matplotlib:

import matplotlib.pyplot as plt #define x and y x = [1, 4, 10] y = [5, 11, 27] #create plot of x and y plt.plot(x, y) #specify x-axis locations x_ticks = [1, 2, 6, 10] #specify x-axis labels x_labels = [1, 2, 6, 10] #add x-axis values to plot plt.xticks(ticks=x_ticks, labels=x_labels)

**Example 3: Set X-Axis Values at Data Points Only**

The following code shows how to set the x-axis values at the data points only:

import matplotlib.pyplot as plt #define x and y x = [1, 4, 10] y = [5, 11, 27] #create plot of x and y plt.plot(x, y) #specify x-axis labels x_labels = ['A', 'B', 'C'] #add x-axis values to plot plt.xticks(ticks=x, labels=x_labels)

**Note:** You can find the complete documentation for the **plt.xticks()** function here.
