Plotting list of lists in a same graph in Python
matplotlib, nested-lists, python
Solution
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.
Below is the plot I get for this case:
Problem
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() ```
