CustomObjects

CustomObjects (up to 200 in one chart) give you the potential, to enhance your charts with graphical figures or images or to add text annotations to your chart. They are independent from any chart or region and may be freely positioned at any pixel position on your chart. CustomObjects get created or altered with one of these functions:

They get identified by their index, which is always the second argument of these functions. If no CustomObject with this index exists, a new one gets created, otherwise the existing one will be overwritten. You can hide an existing CustomObject with RMC_COVisible() or delete one with RMC_CODelete().

The easiest way to explore them is the Designer (RMCDesigner.exe), or check the demo projects for PowerBASIC or VB6 for some examples.
