in Piwik Mobile App I'm trying to display this evolution graph which is a subtable report:,2013-05-18&idSubtable=45&filter_sort_column=nb_hits&column=nb_hits&columns=nb_hits&language=en&width=600&height=300&fontSize=18&showMetricTitle=0&aliasedGraph=1&legendAppendMetric=0&backgroundColor=efefef&gridColor=dcdcdc&colors=cb2026&legendFontSize=18

it outputs the following stack trace:

Notice: Undefined index: period in /home/piwik-demo/www/ on line 441 

Backtrace -->

#7 Piwik_FrontController->dispatch(...) called at [/home/piwik-demo/www/]

I'm not sure whether it is related to [and #3887 but I don't think so. The evolution graph url is generated by this subtable report:

Currently, no evolution graph is working for subtable reports which always results in a blank graph in mobile app. Maybe a quick solution is to not return any evolution graph url in MetadataAPI for subtable reports as mentioned here [#3887]


This bug seems to be fixed.
