I am using vscdoe for python. When I do:
from matplotlib import pyplot
fig, ax = pyplot.subplots()
it will give me a blank plot. However, when I use
ax.plot([1, 2, 3], [1, 4, 6])
in subsequent block, I got a
<matplotlib.lines.Line2D at 0x7f9f118e68b0>
My question is: how can I get the vscode print my plot? Thanks.
You need to use plt.show() right now you're not printing any of your graph out.
import matplotlib.pyplot as plt
plt.plot([1, 2, 3], [1, 4, 6])
plt.show() # this line displays your graph
Now that you know how to print out the graph you could add a title and axises labels.
plt.ylabel('some numbers') # y-axis title
plt.xlabel('other numbers') # x-axis title
plt.title('My Graph') # main title
plt.show()
You forgot to add pyplot.show():
from matplotlib import pyplot
fig, ax = pyplot.subplots()
ax.plot([1, 2, 3], [1, 4, 6])
pyplot.show()
Output:
import matplotlib.pyplot as plt
plt.plot([1, 2, 3], [1, 4, 6])
plt.show()
Here is how I usually do it. It prints out in a nice size!
import matplotlib.pyplot as plt
fig, ax = plt.subplots(figsize=(10, 8))
ax.plot([1, 2, 3], [1, 4, 6])
plt.show()
pyplot.show()?
