From the php class documentation, it doesn't look like the addchartdatafromarray method allows adding link parameters for drilldown charts.
It does look like, however, you can add links with the addDataFromDatabase method in php, which might be an option. You could probably create an array that was structurally similar to the database return, and use this method instead.
In practice, however, it would be much more useful to add these parameters to the addchartdatafromarray method, as most database reads require some manipulation before passing directly into the chart rendering engine. In other words, I don't want to have to write a query for each graph I draw...I want to be able to draw multiple graphs from the same query.
If there isn't a better option, I'll probably write my own method and add it to the php class.
Can I please get confirmation from an admin on this?
Thanks! Great product so far.
