Threshold function breaks graph rendering

[Chris Hoffman]

When the function threshold() is applied, the graph no longer renders. I have tried it on a bunch of different stats and all resulted in a broken graph.

The function looks like this:

threshold(stats.type.subtype, 100)

Others may chime in, but the I have the threshold function working
with the following syntax:

threshold(VALUE,"SOME_TEXT")

e.g.
threshold(1000,"1 Second Baseline")

This draws a solid line for me when using Milliseconds in a timing /
response graph.

Hope that helps.

Ok, it looks like that does work. I guess the Graphite Composer make it looks like you are applying a function on a stat value and asks for a value. I guess the only way to add it is through the 'Add' dialog and not through the 'Special' functions wizard.

I removed threshold from the menu a while back in trunk (r723) as there's no way with the current menu implementation to add functions which are independent targets themselves. I'm going to mark this as closed for now.
