This is the fifth part of a technical note series about creating interactive graphic interfaces with 4D Draw.

Part V explains the code behind the "Graph View" display on the third page of the "BMP Picture Properties" window in the example database, in which a 4D Chart area shows a 3-D graph of the pixel color values in the BMP picture. This is another example of what can be accomplished by reading the bitmap data from a picture document.
