TC documentation states that only positive integer values are supported as a correct value in buildStatisticValue.
Any plans of supporting floats?
How come in version TC 3.0 and earlier there is no such limitation (according to the documentation). I did not check it by myself.
On the followin article guy was able to display float values on the custom charts, does it mean he used v3.0 or earlier? (take a look at the screens)
