vrf Stinkin' markers won't update

Question asked by sordon on Sep 19, 2002
Joel,

since you are using vee 6.xx you can not only read, but also set the
markers. Now, if you try to set your markers to the invalid values you
read when changing the trace, they 'jump' to the correct y-values unless
you have declared them as 'interpolated'.
Just insert a formula box with
         xy.Marker1=xy.Marker1;
         xy.Marker2=xy.Marker2
after the XY-Trace Object.
