How can I set the code that there will be no hover effects, hover options, (hover) links etc on chart?
I'm using chart.js. Below is my code, where I set pie chart.
Html..
<div id="canvas-holder" style="width:90%;"> <canvas id="chart-area" /> </div>
..and js...
$(document).ready(function () { var config = { type: 'pie', data: { datasets: [{ data: [60,20], backgroundColor: [ "#ddd", "#58AC1C" ], label: 'Dataset 1' }], labels: [ "Bla1 ", "Bla2 "+ ] }, options: { responsive: true } }; window.onload = function() { var ctx = document.getElementById("chart-area").getContext("2d"); window.myPie = new Chart(ctx, config); }; });
Is it possible to use chart. js for a desktop/mobile application using html that connects through an esp8266 access point or does it need a wifi connection? @marionboynton, CanvasJS is a standalone library that can work offline without any internet connection.
Other than that the most obvious distinction between the two is that Chart. js is canvas based, while d3. js is mainly about SVG.
Let's get started using Chart.js! First, we need to have a canvas in our page. It's recommended to give the chart its own container for responsiveness.
Tooltips are the little boxes that pop up when you hover over something. (Hovercards are more general, and can appear anywhere on the screen; tooltips are always attached to something, like a dot on a scatter chart, or a bar on a bar chart.)
In order to remove all hover styles/tooltips
from vanilla chart.js:
var myChart = new Chart(canvas, { options: { tooltips: {enabled: false}, hover: {mode: null}, } ... });
Chart.js is watching all mousemove
events on the canvas within which it has instantiated your chart. Setting hover 'mode' to null seems to override all the ways the canvas looks for matching elements to assign activated :hover
classes to.
The tooltip event seems separate, so I had to use both lines to make the chart effectively static.
Note, initial animations still work on a chart with these options.
UPDATE: newest Chart.js has re-bundled the way hover is 'listened' for:
var myChart = new Chart(canvas, { options: { events: [] } ... });
Making the 'events' option an empty list (instead of ['click', 'hover', etc]
) makes the chart blind'/static
because it will be listening for no events.
You can try
showTooltips: false
