go.Isosurface, you can plot isosurface contours of a scalar field
value, which is defined on
In this first example, we plot the isocontours of values
isomax=6. In addition, portions of the sides of the coordinate domains for which the value is between
isomax (named the
caps) are colored. Please rotate the figure to visualize both the internal surfaces and the caps surfaces on the sides.
import plotly.graph_objects as go fig= go.Figure(data=go.Isosurface( x=[0,0,0,0,1,1,1,1], y=[1,0,1,0,1,0,1,0], z=[1,1,0,0,1,1,0,0], value=[1,2,3,4,5,6,7,8], isomin=2, isomax=6, )) fig.show()
Removing caps when visualizing isosurfaces¶
For a clearer visualization of internal surfaces, it is possible to remove the caps (color-coded surfaces on the sides of the visualization domain). Caps are visible by default.
import plotly.graph_objects as go import numpy as np X, Y, Z = np.mgrid[-5:5:40j, -5:5:40j, -5:5:40j] # ellipsoid values = X * X * 0.5 + Y * Y + Z * Z * 2 fig = go.Figure(data=go.Isosurface( x=X.flatten(), y=Y.flatten(), z=Z.flatten(), value=values.flatten(), isomin=10, isomax=40, caps=dict(x_show=False, y_show=False) )) fig.show()
