hello guys,
i thought that my intention should be rather simple but i can't find a proper way to create a graph as descriped below
i want to have a graph in which i see the bug count per day in the backlog over the past 30 days. this information should be presented in a bar graph and i want to have it on my dashboard. maybe i'm just blind but for now i did not find an answer to this...
can some jira wizard help me? 
greetings
jan
