Sir

I wanted to take float datas from a file sink and plot those values .
I am using the below python script for this.
I need to change my x -axis and y-axis limits.
What command should i add to this script for this task?

#!/usr/bin/env python
from array import array
import matplotlib.pyplot as plt

input_file = open(‘mySID_output’,‘r’)
float_array = array(‘d’)

float_array.fromstring(input_file.read())

#print float_array

plt.plot(float_array)
plt.show()

Thank you

Thank you

You need to apply a set_xlim or set_ylim on the axes of the plot.
There should be a way to get the current axes after you’ve created the
plot. Generally, though, what I do is create a figure (plt.figure()),
create a subplot (add_subplot()) and use the subplot to plot and
manipulate the axes.
