Just to provide a cleaner (Dashboard 2.0) approach to this, no need to have multiple arrays/structures:

```auto
var i = 0;
var data = []

while (i < 360) {
    data.push({
        label: i,
        "Axe X": msg.payload.data.x_axis.axis_data[(i)],
        "Axe Y": msg.payload.data.y_axis.axis_data[(i)],
        "Axe Z": msg.payload.data.z_axis.axis_data[(i)],
    })
    i++;
}
msg.payload = data
return msg;

```

Then, on the `ui-chart` node, define the `x` `key` as `label`, then the "Series" property can be "JSON", and you can provide an array of strings here `["Axe X", "Axe Y", "Axe Z"]`, then it will draw the three lines for you
