Experimental Chart.js QML integration

qtchartjs's Issues

Issue with QT 5.12 LTS: Cannot read property 'global' of undefined

Hello Simon,
Thanks a lot for this great implementation. I successfully used it till now in a project in mine, but since an update to QT 5.12, it unfortunatly stopped working.

5.12 brings apparently a lot regarding javascript performance. I tried looking into the issue for about 3 hours now but couldn't even do the slightest progress. I guess my Javascript/QML level simply isn't good enough.

Following error occurs:

qtchartjs/Private/Library.js:9: TypeError: Cannot read property 'global' of undefined

For reference, the line is the following one.
Chart.helpers.merge(Chart.defaults.global, {

It's the first reference to objects in Chart and Chart is defined using
.import "../Library/Chart.bundle.min.js" as Chart

What I tried so far: I tried changing Chart to another import name. Tried to update the Chart.js library to the latest version. Tried to switch to mjs file extension. Tried also the non .min. library (It doesn't bring more informations). Tried to remove the code from the global function and put is directly into the lib.
The file Chart.bundle.min.js is found, I tried importing an non-existing file and it fails differently.
I don't get any step further than that.

Do you have any other ideas? Do you think it's a 5.12 issue?

Can't build the project

When I try to build the project, I get the following error (no matter whether I do it from the terminal or from Qt Creator):

Project ERROR: Project has no top-level .qmake.conf file.

The error occurs while executing the qmake command on src/imports/imports.pro.

RangeError: Maximum call stack size exceeded.

We are trying to implement chart.js into our qml app and are somewhat stuck at the eventListeners.

While some work fine (like 'click') others like hovering over "datapoints" result in

RangeError: Maximum call stack size exceeded.

usually somewhere within (Library.js)

Chart.helpers.merge(Chart.platform, { addEventListener: function(chart, type, listener) {

any clues?
