Setting the time period to 50 days makes the chart disappear without message.

The BurndownChart macro is very useful to show the project's progress unless you need it for a longer period of time which is common in the projects I work for. One example for this is the following invocation:
[[BurndownChart(milestone=Release4.8, startdate=2009-06-10, enddate=2009-07-31)]]
which produces just an empty image tagged "Burndown". The macro might process a longer period of time or at least show a warning message to the user so [s]he might figure out how to use the macro in a way that works. Alternatively, this could be documented in the Wiki if it is not possible to fix the limitation.
I observed this using a Trac 0.10.4 installation.
