Draw graph function in VC4


As customer is asking for drawing the graph functionality in VC4 (PPC2200) and based on this, resultant coordinates will use for logical operation.

Is there any clue to implement this function in VC4? Please suggest.

Thanks in advance.

Basically, the VISAPI library function VA_Line, will allow you total freedom to draw anywhere on the screen, just by providing X,Y coordinates for the starting point and end point of the line, as well as color palette index.

We have used this several times in danish customer projects, to implement graphing functions.

The easiest way is to implement a use library to handle the graph drawing, and then provide a background image for the graph, and then draw on to of that :slight_smile:
