Hallo,
I have tried to implement this plugin in version and it reveals the code of the plugin instead of the graph.
Does anyone know how to fix this?

this code problem can be solved with changing the first line in the Controller.php of this plugin from <? to <?php

Am getting the following error when selecting the widget:

Piwik # web analytics

Date format must be: YYYY-MM-DD, or 'today' or 'yesterday' or any keyword supported by the strtotime function (see http://php.net/strtotime for more information)

Can the plugin not adjust to my locally set date format?

Ich wrde das PLugin auch gern mal testen, aber wie vor mir schon geschrieben wurde:

Das Datumsformat muss YYYY-MM-DD, or 'today' or 'yesterday' oder eine andere, von der Funktion strtotime untersttzte Zeichenkette sein. (Besuchen Sie http://php.net/strtotime fr nhere Informationen)

What can i do (without php-know-how)?

Replying to oputz:
The solution is: don't choose a day-range.
Only today, weekly, monthly and yearly works like it should.

Thank you for building this plugin. now the feature is included in core as per 1.8.3: http://piwik.org/blog/2012/08/new-piwik-release-v1-8-3-features-overview-w-screenshots/
