# Plotly Surface in X/Y instead of Z

Greetings,

I was hoping to plot two orthogonal planes using the Surface graph_object. However, it is seemingly apparent that the shape of the data for z must be two-dimensional (such that x and y are the unique coordinates corresponding in indices to the 2D array that makes up z data). Is there a way to implement this functionality in x or y? I.e.

plot_data = [go.Surface(z=<nxm>, y=<n>, x=<m>),
go.Surface(z=<m>, y=<n>, x=<mxn>)]


where n and m represent the size of the array. The documentation, to me, implies that you should be able to do this: Yet I can’t seem to get it working running v5.11.0.

Alternatively, are there any workarounds to transform the axes to achieve the same goal?

The data the describes the coordinates of the surface is set in z . Data in z should be a 2D list. Coordinates in x and y can either be 1D lists or 2D lists (e.g. to graph parametric surfaces). If not provided in x and y ,

plotly.graph_objects.Surface — 5.11.0 documentation

Planes one represent as a parameterized surface, not as a graph of function of two variables:

import plotly.graph_objects as go
import numpy as np
u, v = np.meshgrid(np.linspace(-1, 2, 100),np.linspace(-1,1, 100))

#Surface  z=1.5
x = u
y = v
z = 1.5*np.ones(u.shape)

fig= go.Figure(go.Surface(x=x, y=y, z=z, coloraxis="coloraxis"))
#Surface y =0.5

s, t = np.meshgrid(np.linspace(-1, 2, 100), np.linspace(-1, 2, 100))
X = s
Z = t
Y = 0.5*np.ones(s.shape)
