I am trying to plot (x,y)
where as y = [[1,2,3],[4,5,6],[7,8,9]]
.
Say, len(x) = len(y[1]) = len(y[2])
..
The length of the y is decided by the User input. I want to plot multiple plots of y in the same graph i.e, (x, y[1],y[2],y[3],...)
. When I tried using loop it says dimension error
.
I also tried: plt.plot(x,y[i] for i in range(1,len(y)))
How do I plot ? Please help.
for i in range(1,len(y)):
plt.plot(x,y[i],label = 'id %s'%i)
plt.legend()
plt.show()
Assuming some sample values for x, below is the code that could give you the desired output.
import matplotlib.pyplot as plt
x = [1,2,3]
y = [[1,2,3],[4,5,6],[7,8,9]]
plt.xlabel("X-axis")
plt.ylabel("Y-axis")
plt.title("A test graph")
for i in range(len(y[0])):
plt.plot(x,[pt[i] for pt in y],label = 'id %s'%i)
plt.legend()
plt.show()
Assumptions: x
and any element in y
are of the same length.
The idea is reading element by element so as to construct the list (x,y[0]'s)
, (x,y[1]'s)
and (x,y[n]'s
.
Edited: Adapt the code if y
contains more lists.
