connect the dots when data doesn't match storage schema

Asked by Matt Snow

The data I am logging is collected at arbitrary times triggered by user action. On the graph I only see dots showing up ever N minutes. The storage schema i'm using for this data is 60:129600 to try allow for random frequency.
I found this Q&A: https://answers.launchpad.net/graphite/+question/64623 but it does not give the result i'm looking for.
i'm hoping that there is a "connect the dots" so to speak function that will draw a like directly from one datapoint to the next.

Is this feature on the roadmap or is there an "undocumented feature" maybe in 0.9.8?

Thanks.

Maybe you could try the "Keep Last Value" function? Not sure if that will do what you want.

that's better than nothing but I am hoping for a single line "connecting the dots".

I had hacked a "connected" line mode a couple of weeks ago to be able to do something like that. Haven't submitted it for merging because I've been playing with it to see how I like it, but seems to work well enough for my purposes. Can put it into its own bzr branch for Chris to grab if there's interest

It's in the tree I keep with all my WIP stuff -- https://github.com/katzj/graphite/commits/devel

And actually, went ahead and pulled out the changes into their own bzr branch and proposed it for merging.

woot! patched my install with revisions 37[6-8] from your branch and it works exactly as I was hoping. :)

+1 for merging this.
