Plotting y=x^2 with Matplotlib

[joseph2015]

TL;DR Summary

Hello all
I would like to plot my outcome with lines. So line 7 workes but it produces markers such as (o or ^). My question is how to make line 8 works to plot lines instead of discrete points?
Thanks in advance

Joe

import matplotlib.pyplot as plt

R = 2

for x in range(0,50):
     y = x**R
#    plt.plot(x,y,marker = 'o')
     plt.plot(x,y,'--')

plt.xlabel('X-axis')
plt.ylabel('Y-axis')
plt.title('plot test')
plt.legend()
plt.show()

Thanks for your reply. However, it will produce points even if i used line code lines.

how about using ls='--' or linestyle='--' ie a keyword argument?

 

[pasmith]

I think you want

plt.plot(x,y,'-')

plt.plot(x,y), no need to put a linestyle into the argument...
