image
Substitutes the standard point symbols with an image.
To display an image instead of series points, assign its URL to the url option. If needed, resize the image using the height and width options. Otherwise, you can assign the URL directly to the image option.
height
Specifies the height of the image used instead of a point marker.
Normally, this option accepts a numeric value, but if you have a range area series, you may want to specify different heights for the minimum and maximum points. In that instance, set the height option to an object with the rangeMinPoint and rangeMaxPoint fields.
url
Specifies the URL of the image to be used as a point marker.
Normally, this option accepts one URL as a string value, but if you have a range area series, you may want to specify different images for the minimum and maximum points. In that instance, set the url option to an object with the rangeMinPoint and rangeMaxPoint fields.
width
Specifies the width of an image that is used as a point marker.
Normally, this option accepts a numeric value, but if you have a range area series, you may want to specify different widths for the minimum and maximum points. In that instance, set the width option to an object with the rangeMinPoint and rangeMaxPoint fields.
