Re: [Matplotlib-users] a quick way to plot 3D surface with point coordination?
Yes, Thanks, Friedrich. :-) This is exactly what I want. By now I know we have to plot over a uniformly sampled plane any way at the end of the day, no matter whether our original data is uniformly sampled or not.

[Matplotlib-users] a quick way to plot 3D surface with point coordination?
Hi, All,
I have a bunch of 3D points with coordinations in a dict
pointset = {
(x1,y1):z1,
(x2,y2):z2,
...
}
It seems I have to
1. fire a loop to change each item and convert the whole dictionary into arrays;
x = []
y = []
for i in pointset.items():
x.append(i[0][0])
y.append(i[0][1])
2. send x and y ranges to meshgrid
3. loop again to put z values into proper positions
4. use plot_surface()
Is there any quicker ways to do that?
And we know that for points with coordination, scatter must be the
simplest way to visualize them.
Is there any trick to convert a scatter graph into a surface picture directly?
Appreciation for any ideas.
