I've started using the Equivolume Charts in Incrediblecharts (Incrediblecharts.com). While I like this style (making fatter bars for the higher volume days), I don't really like the charttng package overall. What other charting software is out there with Equivolume charts? These don't seem to be a standard feature.
eSignal supports Equivolume bars through it's EFS scripting functionality. Here's the FileShare folder with one example: http://share.esignal.com/groupcontents.jsp?folder=EquiVolume&groupid=114 Thanks.
