@pworthing,
The get and set methods of chart are used to access and/or change the available chart properties present in the library once the chart is rendered. However, methods don’t support reading custom properties passed in the chart-options. You can access them using chart.options as shown in the code-snippet below.
chart.options.myField1;
chart.options.myField2;
Kindly take a look at this updated JSFiddle for an example on reading custom properties using chart.options.
