I recently installed Atom as an IDE on my laptop, for university. I installed Hydrogen as a convenient solution to show some plots on the go. But whenever I run Hydrogen, I get this error:
NameError Traceback (most recent call last)
< ipython-input-1-1eb00ff78cf2> in <module>
----> 1 plt.show()
NameError: name 'plt' is not defined
However Matplotlib is working properly when executed normally, and IPython seems to do as well. This is the code I'm trying to run test-wise:
%matplotlib ipympl
import matplotlib.pyplot as plt
a_x=[1,2,3,4,5,6]
a_y=[1,2,3,4,5,6]
plt.plot(a_x, a_y)
plt.show()
A video of the problem is available here.
- Selected
Run
- Resulting error
You have to import the library first. Add this at start of the code.-
from matplotlib import pyplot as plt
- You ran one line, not the whole file.
- You can see the problem by carefully reading the traceback.
Line 9in the script isline 1in the traceback:----> 1 plt.show() - The solution is to run the whole file not one line, i.e. click Run All not Run.
