Issue when displaying a mix of Stacked and Line Graph

[manasg]

Hi,
I ran into a couple of issues when plotting the following scenario -

Metrics
Server1 - Requests Served
Server2 - Requests Served
Total (Server1 + Server2) - Requests Served

Desired Plot
Server1 and Server2 are stacked.
Total is displayed as a line.
Legend - CactiStyle for all three metrics

Setting the area: to stacked in the DSL stacks everything and thus giving the impression that the total is really high.

I tried the stacked function in Graphite

Using the graphite composer ->
/render?
target=stacked(ip-10-245-39-2.requests)&target=stacked(ip-10-244-221-182..requests)&target=sumSeries(ip*..requests)

This works as expected - giving me the desired plot, but I discovered a bug in the CactiStyle Legend - graphite-project/graphite-web#115

I would love to hear any suggestions on the best approach here.
