A minor bug has been detected on the "Evolution in time" and "Compare evolution in time" modules, related to the change of year (new year 2012)
If you notice some strange behavior when showing graphics on a MONTHLY basis in these modules, please upgrade to the latest versions of these two modules to fix the bug. The bug did not appear if working on DAILY mode for the x-axis.
New version for "Evolution in time" is 1.3.2
New version for "Compare evolution in time" is 1.3.1
This is a recommended upgrade.
