Sloupcové grafy

Zdrojový kód

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);

Horizontální pruhové grafy

const xArray = [55, 49, 44, 24, 15];
const yArray = ["Italy","France","Spain","USA","Argentina"];

const data = [{

Koláčové grafy

Chcete-li místo pruhů zobrazit koláč, změňte x a y na štítky a hodnoty a změňte typ na „koláč“:

const data = [{
  labels: xArray,
  values: yArray,
  type: "pie"
}];

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

const data = [{labels:xArray, values:yArray, type:"pie"}];

Plotly.newPlot("myPlot", data, layout);
</script>

Koblihové grafy

Chcete-li místo koláče zobrazit koblihu, přidejte díru:

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

Vykreslování rovnic

Zdrojový kód

let exp = "Math.sin(x)";

// Generate values
const xValues = [];
const yValues = [];
for (let x = 0; x <= 10; x += 0.1) {
  xValues.push(x);
  yValues.push(eval(exp));
}

// Display using Plotly
const data = [{x:xValues, y:yValues, mode:"lines"}];
const layout = {title: "y = " + exp};
Plotly.newPlot("myPlot", data, layout);

const layout = {title: "y = " + exp};
Plotly.newPlot("myPlot", data, layout);

Bublinové spiknutí

Bublinové grafy jsou bodové grafy, jejichž značky mají proměnlivou barvu, velikost a symboly.

Jedná se o typ 3-rozměrného grafu s pouze dvěma osami (x a y), kde je velikost bubliny komunikuje třetí dimenzi.

Zdrojový kód

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);
