It provides more control over the appearance of each edge. My approach is to define first the plot size (or axis values), as this will change depending on the job run. tri import Does your data describe triangles in 3D space? It sounds like there are continuous ranges of xy vals that map to a single z point, which I think means you have triangles. Master triangular meshes, parametric surfaces, and complex mathematical visualizations. axvline, import matplotlib. When drawing shapes where xref or yref reference axes of type category or multicategory, you can shift x0, x1, y0, and y1 away from the center of the category using x0shift, x1shift, y0shift, The most likely reason is that you used data units for the x arguments when calling axhspan. mplot3d import Matplotlib: A comprehensive library for creating static, animated, and interactive visualizations in Python.
