I've been mulling this over myself. The only idea I've had is to build a custom probe that uses the new arithmetic features to add the desired values together into a variable, which you then put in the info window display. It should show up as an underlined value, which you can then click on to put into a strip chart.
I haven't tested this yet, but I don't see why it wouldn't work. It's a pain in the butt, though, having to do a custom probe for each new chart you might want. How would I implement this feature? I think I'd add it to the strip chart interface rather than stick it into the probes. Probes should be simple data-collecting entities and shouldn't have a lot of calculation buried in them, IMHO. Besides, users shouldn't be forced to deal with probe file internals on a regular basis. I envision something under the Data tab in the Chart Options dialog, a button called New Calculated Value or something like that. When clicked, it opens up a window into which you can type a formula, the result of which will be the value that's graphed on the chart. Ideally, the variables will be dragged from the Get Info windows, just like how they get added to a strip chart today. In other words, instead of dragging values directly into a strip chart, you drag them into a calculation field and put operators between them. Failing this, an all-textual system would work. Something like how Excel works - you can include values from other spreadsheets by using a special syntax that prefixes the name of the spreadsheet before the cell reference. This might allow us to graph values from probes on different maps, too. Hmmm.... OK, back to work for me.
