Expand description

Generates a 3D a surface (or wireframe, or both)

Example

// import
use plotpy::*;
use std::path::Path;

// directory to save figures
const OUT_DIR: &str = "/tmp/plotpy/doc_tests";

// generate (x,y,z) matrices
let n = 21;
let mut x = vec![vec![0.0; n]; n];
let mut y = vec![vec![0.0; n]; n];
let mut z = vec![vec![0.0; n]; n];
let (min, max) = (-2.0, 2.0);
let d = (max - min) / ((n - 1) as f64);
for i in 0..n {
    let v = min + (i as f64) * d;
    for j in 0..n {
        let u = min + (j as f64) * d;
        x[i][j] = u;
        y[i][j] = v;
        z[i][j] = u * u - v * v;
    }
}

// configure and draw surface + wireframe
let mut surface = Surface::new();
surface.colormap_name = "seismic".to_string();
surface.colorbar = true;
surface.wireframe = true;
surface.line_width = 0.3;
surface.draw(&x, &y, &z);

// add surface to plot
let mut plot = Plot::new();
plot.add(&surface);
plot.camera(20.0, 35.0); // must be after add surface

// save figure
let path = Path::new(OUT_DIR).join("doc_surface.svg");
plot.title("horse saddle equation");
plot.save(&path)?;

Fields

row_stride: i32

Row stride

col_stride: i32

Column stride

surface: bool

Generates a surface

wireframe: bool

Generates a wireframe

colormap_index: i32

Colormap index

  • 0 – bwr
  • 1 – RdBu
  • 2 – hsv
  • 3 – jet
  • 4 – terrain
  • 5 – pink
  • 6 – Greys
  • >6 – starts over from 0
colormap_name: String

Colormap name as defined in https://matplotlib.org/stable/tutorials/colors/colormaps.html

Will use colormap_index instead if colormap_name is empty.

colorbar: bool

Draw a colorbar

colorbar_label: String

Colorbar label

colorbar_number_format: String

Number format for the labels in lines contour (e.g. “%.2f”)

line_color: String

Color of wireframe lines

line_style: String

Style of wireframe line

Options: “-”, “:”, “--”, “-.

line_width: f64

Width of wireframe line

Implementations

Creates a new Surface object

Draws a surface, or wireframe, or both

Input

  • x – matrix with x values
  • y – matrix with y values
  • z – matrix with z values

Flags

The following flags control what features are not to be drawn:

  • surface – draws surface
  • wireframe – draws wireframe

Notes

  • The type T of the input matrices must be a number.
