JavaScript/jQuery PolarChart - series.point.image
Default Value: undefined
In a common case, chart points are represented by default point markers. However, you can use a custom image as a point marker. To do this, specify the properties of the image object. Assign a URL leading to your image to the url property. If the size of your image does not correspond to your needs, specify the width and height properties.
NOTE
If you do not need to resize your image, you can assign an image URL directly to the image field.
