[Chartjs]-$(…).getContext("2d") is not a function when using chart.js

This has been answered already but, in case someone stumbles upon this post, to get the function getContext to work make sure you are rendering the chart inside a <canvas id='myChart'> </canvas> element.

when attempting to retrieve getContext(“2d”) on an element using jquery, you need to alter the syntax slightly so that the dom ‘node’ is returned, rather than a jquery object. The correct syntax in this case is;

$("#myChart")[0].getContext("2d");

note the addition of [0]

getContext is a method for javascript, use:

document.getElementById('myChart').getContext('2d');

for JQuery use:

$("#myChart").get(0).getContext("2d");
