I’ve been using the plugin, and found one problem with it.
I wanted to use js to cause the flash chart to reload data, but in order to do so, I need the id of the flash obj. There is no way currently to get this that I could find, as the _ofc method throws a seq # in as part of the id, so I changed these methods a bit to add a final param to pass in the id. I did it as an extra param, probably would be more extensible to pass in a hash of options, and have one of them be the id of the flash obj. What do you think, is there a better way to do this?

@Andrew – I think I see what you are saying. You want to reload the data that is in the div, where the div has an id like my_chart and some string? I think a solution would be to give the div a css class, then you can use prototype’s css selector like this $$(‘.ofc_chart’) to get all the open flash chart divs on the page and you can reload each one or get the id of each one and go from there. Thoughts?

Can the line charts be oriented vertically?

Thanks, Scott

@Scott – There is probably a trick to it, but not anything off the top of my head. I am using the swf from http://teethgrinder.co.uk/open-flash-chart/, and from what I can tell, it is not supported. But again, maybe there is a way to rotate the flash after the fact or some other trick?
