JS Ploty

Plotly.js is defined as a charting library that comes with over 40 chart types, 3D charts, statistical graphs, and SVG maps.

Scatter Plots

Example

<!DOCTYPE html>

<html>

<body>

var xArray = [50,60,70,80,90,100,110,120,130,140,150];

var yArray = [7,8,8,9,9,9,10,11,14,14,15];

// Define Data

var data = [{

x:xArray,

y:yArray,

mode:”markers”

}];

// Define Layout

var layout = {

xaxis: {range: [40, 160], title: “Square Meters”},

yaxis: {range: [5, 16], title: “Price in Millions”},

title: “House Prices vs. Size”

};

// Display using Plotly

Plotly.newPlot(“myPlot”, data, layout);

</script>

</body>

</html>

Output

Another Example

<!DOCTYPE html>

<html>

<body>

var xArray = [50,60,70,80,90,100,110,120,130,140,150];

var yArray = [7,8,8,9,9,9,10,11,14,14,15];

// Define Data

var data = [{

x: xArray,

y: yArray,

mode:”lines”

}];

// Define Layout

var layout = {

xaxis: {range: [40, 160], title: “Square Meters”},

yaxis: {range: [5, 16], title: “Price in Millions”},

title: “House Prices vs. Size”

};

// Display using Plotly

Plotly.newPlot(“myPlot”, data, layout);

</script>

</body>

</html>

Output

Linear Graphs

Example

<!DOCTYPE html>

<html>

<body>

var exp = “x + 17”;

// Generate values

var xValues = [];

var yValues = [];

for (var x = 0; x <= 10; x += 1) {

xValues.push(x);

yValues.push(eval(exp));

}

// Define Data

var data = [{

x: xValues,

y: yValues,

mode:”lines”

}];

// Define Layout

var layout = {title: “y = ” + exp};

// Display using Plotly

Plotly.newPlot(“myPlot”, data, layout);

</script>

</body>

</html>

Output

Multiple Lines

Example

<!DOCTYPE html>

<html>

<body>

var exp1 = “x”;

var exp2 = “1.5*x”;

var exp3 = “1.5*x + 7”;

// Generate values

var x1Values = [];

var x2Values = [];

var x3Values = [];

var y1Values = [];

var y2Values = [];

var y3Values = [];

for (var x = 0; x <= 10; x += 1) {

x1Values.push(x);

x2Values.push(x);

x3Values.push(x);

y1Values.push(eval(exp1));

y2Values.push(eval(exp2));

y3Values.push(eval(exp3));

}

// Define Data

var data = [

{x: x1Values, y: y1Values, mode:”lines”},

{x: x2Values, y: y2Values, mode:”lines”},

{x: x3Values, y: y3Values, mode:”lines”}

];

//Define Layout

var layout = {title: “[y=” + exp1 + “] [y=” + exp2 + “] [y=” + exp3 + “]”};

// Display using Plotly

Plotly.newPlot(“myPlot”, data, layout);

</script>

</body>

</html>

Output

Bar Charts

Example

<!DOCTYPE html>

<html>

<body>

var xArray = [“Italy”, “France”, “Spain”, “USA”, “Argentina”];

var yArray = [55, 49, 44, 24, 15];

var data = [{

x:xArray,

y:yArray,

type:”bar”

}];

var layout = {title:”World Wide Wine Production”};

Plotly.newPlot(“myPlot”, data, layout);

</script>

</body>

</html>

Output

Horizontal Bar Charts

Example

<!DOCTYPE html>

<html>

<body>

var xArray = [55, 49, 44, 24, 15];

var yArray = [“Italy “, “France “, “Spain “, “USA “, “Argentina “];

var data = [{

x:xArray,

y:yArray,

type:”bar”,

orientation:”h”,

marker: {color:”rgba(255,0,0,0.6)”}

}];

var layout = {title:”World Wide Wine Production”};

Plotly.newPlot(“myPlot”, data, layout);

</script>

</body>

</html>

Output

Pie Charts

To display a pie instead of bars, change x and y to labels and values, and change the type to “pie”:

Example

<!DOCTYPE html>

<html>

<body>

var xArray = [“Italy”, “France”, “Spain”, “USA”, “Argentina”];

var yArray = [55, 49, 44, 24, 15];

var layout = {title:”World Wide Wine Production”};

var data = [{labels:xArray, values:yArray, type:”pie”}];

Plotly.newPlot(“myPlot”, data, layout);

</script>

</body>

</html>

Output

Donut Charts

To display a donut instead of a pie, add a hole:

Example

<!DOCTYPE html>

<html>

<body>

var xArray = [“Italy”, “France”, “Spain”, “USA”, “Argentina”];

var yArray = [55, 49, 44, 24, 15];

var layout = {title:”World Wide Wine Production”};

var data = [{labels:xArray, values:yArray, hole:.4, type:”pie”}];

Plotly.newPlot(“myPlot”, data, layout);

</script>

</body>

</html>

Output

Plotting Equations

Example

<!DOCTYPE html>

<html>

<body>

var exp = “Math.sin(x)”;

// Generate values

var xValues = [];

var yValues = [];

for (var x = 0; x <= 10; x += 0.1) {

xValues.push(x);

yValues.push(eval(exp));

}

// Display using Plotly

var data = [{x:xValues, y:yValues, mode:”lines”}];

var layout = {title: “y = ” + exp};

Plotly.newPlot(“myPlot”, data, layout);

</script>

</body>

</html>
