|
||
// Purpose: Every property in the chart references images by names.
|
||
// This means that you can set MarkerImage property to a
|
||
// full image path or URL. In case when the user wants to
|
||
// dynamically generate an image or load it from other
|
||
// location (like database) you can use named image
|
||
// collection which is exposed as Images property of the
|
||
// chart. Any Image can be added to this collection with
|
||
// unique name and than this name can be used in all the
|
||
// chart properties which require image names.
