I built a small piece of code to plot some data.
I built it on my Oracle VirtualBox and it worked.
I moved it to production, and had the sys admin install the code and the libraries, etc.
Now the matplotlib.pyplot section is failing.
I tried a simple snippet
from matplotlib.pyplot import *
time = [0, 1, 2, 3]
position = [0, 100, 200, 300]
plt.plot(time, position)
plt.xlabel('Time (hr)')
plt.ylabel('Position (km)')
and get...
qt.qpa.screen: QXcbConnection: Could not connect to display
I don't even want to see this on the screen, I just want to create a png for a web site.
How can the code be re-written to connect to the display?
take off the "plt." and it will work
from matplotlib.pyplot import *
time = [0, 1, 2, 3]
position = [0, 100, 200, 300]
plot(time, position)
xlabel('Time (hr)')
ylabel('Position (km)')
