Support 2D list as input #1021
Description
Description of the problem
PyGMT doesn't allow 2D list as input.
Full code that generated the error
The script below doesn't work:
import pygmt
fig = pygmt.Figure()
fig.plot(data=[[0, 0]], region=[-2, 2, -2, 2], frame=True, style="c0.5c", pen="1p")
fig.show()but it works if I convert it to a 2D numpy array:
import pygmt
fig = pygmt.Figure()
fig.plot(data=np.array([[0, 0]]), region=[-2, 2, -2, 2], frame=True, style="c0.5c", pen="1p")
fig.show()Full error message
