How do you make the x axis of the chart and graph only show data for ten seconds

To make the x axis of a chart or graph show data for only ten seconds, you need to set the minimum and maximum values of the x axis to correspond to the time range you want to display.

For example, if you have a data set that updates every second and you want to display only the past ten seconds of data, you can set the minimum value of the x axis to be ten seconds less than the current time, and the maximum value to be the current time.

Here is some sample code in Python using the Matplotlib library to set the x axis of a line chart to show only the past ten seconds of data:

import matplotlib.pyplot as plt
import datetime

# Get current time
now = datetime.datetime.now()

# Generate some sample data
data = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15]
timestamps = [now - datetime.timedelta(seconds=i) for i in range(len(data))]

# Plot the data
fig, ax = plt.subplots()
ax.plot(timestamps, data)

# Set the x axis limits to show only the past ten seconds
ax.set_xlim(now - datetime.timedelta(seconds=10), now)

# Display the chart
plt.show()

This code generates some sample data and timestamps for the past 15 seconds, then plots the data on a line chart. The x axis limits are set to show only the past ten seconds of data, and the chart is displayed using the `plt.show()` function.
