Chat.js Axis ID Issue that doesn't recognize non-default `x y r` axis IDs

[RicSanOP]

I am using the advanced functionality of the plugin to renderRaw a chart that has a dual y-axis. However, after a lot of time trying to ensure that my formatting was correct, and playing around with axis IDs, it seems that the plugin or chart.js is unable to process axis that don't have the default IDs x, y, z. Although, I originally ran into this issue whilst using the window.renderChart function, here is an advanced-chart JSON config that simply does not render the points of non default axis IDs. I hope that there is a simple fix to this issue.

```advanced-chart
{
    "data": {
        "datasets": [
            {
                "type": "bar",
                "data": [{"x": 1, "y": 30}, {"x": 2, "y": 20}, {"x": 3, "y": 10}],
                "yAxisId": "y",
                "order": 0,
                "backgroundColor": "#00FF0080",
                "borderColor": "#00FF00"
            },
            {
                "type": "line",
                "data": [{"x": 1, "y2": 10}, {"x": 2, "y2": 10}, {"x": 3, "y2": 10}],
                "yAxisId": "y2",
                "order": 1,
                "backgroundColor": "#FF000080",
                "borderColor": "#FF0000"
            }
        ]
    },

        "responsive": true,
        "plugins": {
            "legend": {

            }
        },
        "scales": {
            "x": {
                "type": "linear",

            },
            "y": {
                "type": "linear",
                "position": "left"
            }, 
            "y2": {
                "type": "linear",
                "position": "right"
            }
        }
    }
}
