We'd like to improve the SPOCS 2.0 trend system. Right now, it produces what are actually CSV (comma-seperated-variables) files for trending, although the files are called .TXT. The system as it is right now, has a routine that appears in the HTML module, that converts the current trend file into XML. Why do this, you ask? Currently, we are using Fusion Charts Free to generate web-based trend charts. This package wants its data in XML.
We are playing around with amCharts right now. amCharts will take XML or CSV formatted data. If we can get amCharts to use our CSV data, we can stamp out the XML converter. Also, we want to have the ability to look at older data files. Looks like amCharts might be able to do that, too. We'll see.
