Bar Charts

Source Code

Example Code

javascript
Try it Yourself
const xArray = ["Italy","France","Spain","USA","Argentina"];

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

const data = [{

  x: xArray,

  y: yArray,

  type: "bar",

  orientation:"v",

  marker: {color:"rgba(0,0,255)"}

}];

const layout = {title:"World Wide Wine Production"};

Plotly.newPlot("myPlot", data, layout);

Plotting Equations

Source Code

Example Code

javascript
Try it Yourself
let exp = "Math.sin(x)";

// Generate values

const xValues = [];

const yValues = [];

for (let x = 0; x

### Example

javascript // Display using Plotly

const data = [{x:xValues, y:yValues, mode:"markers"}];

const layout = {title: "y = " + exp};

Plotly.newPlot("myPlot", data, layout);

## Scatter Plots

### Source Code

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

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

// Define Data

const data = [{

x: xArray,

y: yArray,

mode:"markers",

type:"scatter"

}];

// Define Layout

const layout = {

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

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

title: "House Prices vs. Size"

};

Plotly.newPlot("myPlot", data, layout);

## Line Graphs

### Source Code

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

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

// Define Data

const data = [{

x: xArray,

y: yArray,

mode: "lines",

type: "scatter"

}];

// Define Layout

const 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);

## Bubble Plots

Bubble Plots are Scatter Plots whose markers have variable color, size, and symbols.

It is a type of 3-dimensional chart with only two axes (x and y) where the size of the bubble communicates the third dimention.

### Source Code

javascript const xArray = [1,2,3,4];

const yArray = [10,20,30,40];

const trace1 = {

x: xArray,

y: yArray,

mode: 'markers',

marker: {

color: ['red', 'green', 'blue', 'orange'],

size: [20, 30, 40, 50]

}

};

const data = [trace1];

const layout = {

title: "Plotting Bubbles"

};

Plotly.newPlot('myPlot', data, layout);

## Linear Graphs

### Source Code

javascript let exp = "x + 17";

// Generate values

const xValues = [];

const yValues = [];

for (let x = 0; x

Source Code

```javascript let exp1 = "x";

let exp2 = "1.5*x";

let exp3 = "1.5*x + 7";

// Generate values

const x1Values = [];

const x2Values = [];

const x3Values = [];

const y1Values = [];

const y2Values = [];

const y3Values = [];

for (let x = 0; x
