  • Redraw Question - Graph Markers

    I’m using EmWin – I’m working with the graph function – I have created
    objects and a couple of markers that I move back and forth along the graph. The
    problem I’m having is that the graph appears to redrawing all the objects when I
    move a marker along the graph and it slows up the functionality the more objects
    I have on the graph. Is there away (or any sample code) that would allow me just
    to redraw the marker and not the whole object. I thinking I need to use the
    validate call but there done not seem to be pone for the graph object – anyway
    and help on this would be appreciated.

    Should the window invalidate / validate be used?

    Any assistance gudiance would be apprciates.
