Re: [foxboro] Marker Movement

There is another option as well. Lots of markers moving up and down with the
visibility controlling which one you see. This will give the appearance of
one marker moving in both directions within the granularity of the # of
markers and the resolution on your visibility control.

Of course, it requires logic to control the visibility flags.

        Have you considered using XY plots?

        They work in both directions on a grid using markers.  They will
also leave
        a trail (if desired) and have some controls like clear etc.  You can
overlay
        them on a polygon to create the appearance of shaded areas of the
plot.

        I have a question about marker movement. I haven't had a problem
until I
        tried to get a marker to move with both row location < and col
location <(2
        separate inputs). What we are trying to do is get a marker to plot
within a
        grid on the display. When I configure the row location and then the
col
        location, the column works perfectly but the row location is
distorted. If
        I reverse the configuration order and do the Column then the row,
then the
        row works correctly and column is distorted.

        The question is how do you get a marker to move accurately in both
        directions with the two separate inputs. Where can I go and find the
        information explaining how/why this is done. The information I have
briefly
        explains marker movement, but I have not found anything explaining
this or
        I just don't understand what I have read.

        I am using Foxboro  I/A legacy DM at version 4.3 on AP51B's, WP30's,
        WP51B's.

        Thanks for the help in advance
