  type: “bar”,
  data: {},
  options: {}
});




Scatter Plots

House Prices vs. Size

Source Code

const xyValues = [
  {x:50, y:7},
  {x:60, y:8},
  {x:70, y:8},
  {x:80, y:9},
  {x:90, y:9},
  {x:100, y:9},
  {x:110, y:10},
  {x:120, y:11},
  {x:130, y:14},
  {x:140, y:14},
  {x:150, y:15}
];











new Chart(“myChart”, {
  type: “scatter”,
  data: {
    datasets: [{
      pointRadius: 4,
      pointBackgroundColor: “rgba(0,0,255,1)”,
      data: xyValues
    }]
  },
  options:{…}
});

Line Graphs

House Prices vs. Size

Source Code

const xValues = [50,60,70,80,90,100,110,120,130,140,150];
const yValues = [7,8,8,9,9,9,10,11,14,14,15];

new Chart(“myChart”, {
  type: “line”,
  data: {
    labels: xValues,
    datasets: [{
      backgroundColor:”rgba(0,0,255,1.0)”,
      borderColor: “rgba(0,0,255,0.1)”,
      data: yValues
    }]
  },
  options:{…}
});

If you set the borderColor to zero, you can scatter plot the line graph:

Multiple Lines

Source Code

const xValues = [100,200,300,400,500,600,700,800,900,1000];

new Chart(“myChart”, {
  type: “line”,
  data: {
    labels: xValues,
    datasets: [{
      data: [860,1140,1060,1060,1070,1110,1330,2210,7830,2478],
      borderColor: “red”,
      fill: false
    },{
      data: [1600,1700,1700,1900,2000,2700,4000,5000,6000,7000],
      borderColor: “green”,
      fill: false
    },{
      data: [300,700,2000,5000,6000,4000,2000,1000,200,100],
      borderColor: “blue”,
      fill: false
    }]
  },
  options: {
    legend: {display: false}
  }
});

Linear Graphs

Source Code

const xValues = [];
const yValues = [];
generateData(“x * 2 + 7”, 0, 10, 0.5);

new Chart(“myChart”, {
  type: “line”,
  data: {
    labels: xValues,
    datasets: [{
      fill: false,
      pointRadius: 1,
      borderColor: “rgba(255,0,0,0.5)”,
      data: yValues
    }]
  },
  options: {…}
});











function generateData(value, i1, i2, step = 1) {
  for (let x = i1; x <=>
    yValues.push(eval(value));
    xValues.push(x);
  }
}

Function Graphs

Same as Linear Graph. Just change the generateData parameter(s):

generateData(“Math.sin(x)”, 0, 10, 0.5);
