Bug Description
Some of collectd plugins (MySQL for example) are not always updating all the values they monitor. As a result I can have 10 RRDs in a graph but only 9 of them have current values. What Jarmon does in that kind of situation is drawing one or two RRDs as usual and leaves the rest of the graph empty instead of drawing 9 RRDs.
It seems to me that jarmon draws those RRD files sequentially and after every one of them sets some "last update time" or something and then ignores any correct values newer than this timestamp.
Important is - when graph is without STACKED_OPTIONS, this problem doesn't show (took me some time to notice).
