# 3D Isosurface Plots in JavaScript

How to make 3D isosurface 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.

### Basic Isosurface Plot

var data = [
{
type: "isosurface",
x: [0,0,0,0,1,1,1,1],
y: [0,1,0,1,0,1,0,1],
z: [1,1,0,0,1,1,0,0],
value: [1,2,3,4,5,6,7,8],
isomin: 2,
isomax: 6,
colorscale: "Reds"
}
];

var layout = {
margin: {t:0, l:0, b:0},
scene: {
camera: {
eye: {
x: 1.88,
y: -2.12,
z: 0.96
}
}
}
};

Plotly.newPlot('myDiv', data, layout, {showSendToCloud: true});


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

var data = [
{
type: "isosurface",
x: unpack(rows, 'x'),
y: unpack(rows, 'y'),
z: unpack(rows, 'z'),
value: unpack(rows, 'value'),
isomin: -100,
isomax: 100,
surface: {show: true, count: 1, fill: 0.8},
slices: {z: {
show: true, locations: [-0.3, 0.5]
}},
caps: {
x: {show: false},
y: {show: false},
z: {show: false}
},
}
];

var layout = {
margin: {t:0, l:0, b:0},
scene: {
camera: {
eye: {
x: 1.86,
y: 0.61,
z: 0.98
}
}
}
};

Plotly.newPlot('myDiv', data, layout, {showSendToCloud: true});
});


### Multiple Isosurfaces with Caps

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

var data = [
{
type: "isosurface",
x: unpack(rows, 'x'),
y: unpack(rows, 'y'),
z: unpack(rows, 'z'),
value: unpack(rows, 'value'),
isomin: -10,
isomax: 10,
surface: {show: true, count: 4, fill: 1, pattern: 'odd'},
caps: {
x: {show: true},
y: {show: true},
z: {show: true}
},
}
];

var layout = {
margin: {t:0, l:0, b:0},
scene: {
camera: {
eye: {
x: 1.86,
y: 0.61,
z: 0.98
}
}
}
};

Plotly.newPlot('myDiv', data, layout, {showSendToCloud: true});
});
