# 3D Line Plots in JavaScript

How to make 3D line plots in javascript.

New to Plotly?

Plotly is a free and open-source graphing library for JavaScript. We recommend you read our Getting Started guide for the latest installation or upgrade instructions, then move on to our Plotly Fundamentals tutorials or dive straight in to some Basic Charts tutorials.

### 3D Line Plot

d3.csv('https://raw.githubusercontent.com/plotly/datasets/master/3d-line1.csv', function(err, rows){
function unpack(rows, key) {
return rows.map(function(row)
{ return row[key]; }); }

var x = unpack(rows , 'x');
var y = unpack(rows , 'y');
var z = unpack(rows , 'z');
var c = unpack(rows , 'color');
Plotly.newPlot('myDiv', [{
type: 'scatter3d',
mode: 'lines',
x: x,
y: y,
z: z,
opacity: 1,
line: {
width: 6,
color: c,
reversescale: false
}
}], {
height: 640
});
});


### 3D Line + Markers Plot

var pointCount = 31;
var i, r;

var x = [];
var y = [];
var z = [];
var c = [];

for(i = 0; i < pointCount; i++)
{
r = 10 * Math.cos(i / 10);
x.push(r * Math.cos(i));
y.push(r * Math.sin(i));
z.push(i);
c.push(i)
}

Plotly.newPlot('myDiv', [{
type: 'scatter3d',
mode: 'lines+markers',
x: x,
y: y,
z: z,
line: {
width: 6,
color: c,
colorscale: "Viridis"},
marker: {
size: 3.5,
color: c,
colorscale: "Greens",
cmin: -20,
cmax: 50
}},
]);

### 3D Line Spiral Plot

var pointCount = 3142;
var i, r;

var x = [];
var y = [];
var z = [];
var c = [];

for(i = 0; i < pointCount; i++)
{
r = i * (pointCount - i);
x.push(r * Math.cos(i / 30));
y.push(r * Math.sin(i / 30));
z.push(i);
c.push(i)
}

Plotly.newPlot('myDiv', [{
type: 'scatter3d',
mode: 'lines',
x: x,
y: y,
z: z,
opacity: 0.7,
line: {
width: 10,
color: c,
colorscale: 'Viridis'}
}]);

### 3D Random Walk Plot

d3.csv('https://raw.githubusercontent.com/plotly/datasets/master/_3d-line-plot.csv', function(err, rows){
function unpack(rows, key) {
return rows.map(function(row)
{ return row[key]; });
}

var trace1 = {
x: unpack(rows, 'x1'),
y: unpack(rows, 'y1'),
z: unpack(rows, 'z1'),
mode: 'lines',
marker: {
color: '#1f77b4',
size: 12,
symbol: 'circle',
line: {
color: 'rgb(0,0,0)',
width: 0
}},
line: {
color: '#1f77b4',
width: 1
},
type: 'scatter3d'
};

var trace2 = {
x: unpack(rows, 'x2'),
y: unpack(rows, 'y2'),
z: unpack(rows, 'z2'),
mode: 'lines',
marker: {
color: '#9467bd',
size: 12,
symbol: 'circle',
line: {
color: 'rgb(0,0,0)',
width: 0
}},
line: {
color: 'rgb(44, 160, 44)',
width: 1
},
type: 'scatter3d'
};

var trace3 = {
x: unpack(rows, 'x3'),
y: unpack(rows, 'y3'),
z: unpack(rows, 'z3'),
mode: 'lines',
marker: {
color: '#bcbd22',
size: 12,
symbol: 'circle',
line: {
color: 'rgb(0,0,0)',
width: 0
}},
line: {
color: '#bcbd22',
width: 1
},
type: 'scatter3d'
};

var data = [trace1, trace2, trace3];
var layout = {
title: '3D Line Plot',
autosize: false,
width: 500,
height: 500,
margin: {
l: 0,
r: 0,
b: 0,
t: 65
}
};
Plotly.newPlot('myDiv', data, layout);
});
