I’m using this JS to generate a github activity chart. I can successfully load it up but I’m struggling to find a way to update the data after its first initialization:
var processedData = [];
$(document).ready(function () {
});
$('#activityMap').github_graph({
data: processedData,
texts: ['activity', 'activities']
});
This results in this chart:
And then I call get_activity() to load new activity from my database:
function get_activity() {
$.ajax({
url: "?handler=LoadActivity",
success: function (data) {
var activities = JSON.parse(data).activities;
//updated activity
processedData = processActivitiesData(activities);
//I tried reinitializing here:
$('#activityMap').github_graph({
data: processedData,
texts: ['activity', 'activities']
});`
},
error: function (error) {
}
});
}
However that reinit doesnt work and results in:
Uncaught TypeError: $(...).github_graph is not a function
Referring to how the library is structured, I can only guess that it can’t be called as a normal function and reinit. Instead needs to be called on the top-level of the JS and can’t be nested. How can I update the library’s initialization to support this so that I can async call my new activity?
The library JS in reference:
