Editor to share with you Matlab how to achieve three-dimensional data visualization, I hope you will learn something after reading this article, let's discuss it together!

3D data visualization

1. Three-dimensional graphics

Plot3 (x ~ y ~ z): where the parameters x ~ y and z are vectors or matrices with the same dimension.

Mesh () to draw a 3D grid

Surf () draws colored 3D surface drawings

two。 Special 3D drawing

Cylinder () generates the data of the cylinder chart, and then uses mesh to draw the three-dimensional body of rotation conveniently.

Sphere (): spherical graph

Contour3 (): 3D contours

Bar3 (): bar chart bar3h () horizontal 3D column chart

Pie3 (): pie chart

Scatter3 (): 3D scatter plot

3. Set the viewing angle

View (az,el): az is the azimuth, el is the elevation

View ([x y z]): points to the direction indicated by the vector [x y z]

View (2): two-dimensional perspective

View (3): 3D Visual Angle

Rotate3d on/off: turns 3D viewing on or off

4. Color control

Rgbplot () draws a color diagram

Colorbar (): horizontal color bar

Colormap (): vertical color bar

5. Illumination effect

Light ()

6. Output of graphics
