Z3d

Example

About

Generate interactive 3d plots with a simple function call. Function returns a Three.js scene which can be customized as needed.

Basic function call generates a X-Y-Z scatter plot. Optional configuration object can be used to change color and size values.

Install

bower install z3d

Usage

Why use Z3d? Because configuration is optional, an interactive 3d plot with sensible defaults can be generated with as little as a single line.

Plotting function takes the data to plot and an optional configuration object.

###Basic Example (no configuration)

      var x = [-0.8234, 0.0952, 1.9594, -0.2831, -0.4147, 1.5859, 0.5326, 0.0925, 0.3293, 1.3635, 0.3396, 0.0677, -0.6739, 0.4084, -1.4487, -0.1101, -0.7521, -1.2118, 1.7191, 0.2020, -0.1573, -0.2298, -0.8230, 1.7924, 0.4511];

      //AND THIS IS HOW WE PLOT IT:
      var plot = plot3d(x,y,z);

###Example With Configuration

We can add a configuration object to the example above to modify the height/width of our plot, the DOM element the visualization is appended to, the labels on the points plotted, the size of the points plotted, and the color of the points plotted.

        var string = '';

        color: colors,
        label: labs,
        //height and width of the DOM element
        height: 400,
        width: 400,
