I once used a charting program (chartmaster) that allowed adding of 
series once the chart was first defined. Each time you added a series 
you could define the presentation (line, bar, x-y, scatter).
This way a chart could be made up of as many types as desired. If you 
wanted a straight line across your chart you just defined a 2 point xy 
series as line type.
You could add series from different columns and different files. This 
was a proper charting program and not a graphical representation of some 
selected spreadsheet data.
