Drag and Drop chart disappears

[Eric]

Hi. New to Google Visualization and I have a problem where I can't
seem to find an answer. I'm hoping someone has run into this before
and can point me in the right direction. I have 4 visualizations in 2
columns with each visualization created via an include statement.

The page loads fine and I can drag and drop each visualization box
where I want it. The problem is that once I move a visualization, it
goes blank/disappears. The only way to get it back is to do a
complete refresh of the page.

Is there a way to overcome this fairly easily? What am I doing
wrong? Can I (or how would I) redraw a graph when it is populated via
an include statement?

Thanks for any help.

I've run into similar issues with drag and drop. Have you looked into
using ajax to redraw the chart anytime it's moved? This way you don't
have to reload the whole page and it only reloads the ones it needs.
We use the same layout you described to display charts and allow users
to move them around their dashboard. We already used ajax to display
the charts so it was simple extension to redraw anytime they were
moved. Depending on the data passed into the include file you might
be able to implement an ajax call that gets the contents of your
include file. I imagine the D&D plug-in you're using has an event hook
you can use to call the ajax function (we've been using the plugin
from JQuery UI).
Hope this helps! Good luck!
