stacked line chart x-axis is confusing #98

This may not be a bug, but the x axis on my chart http://daytum.com/panels/16573
is a little confusing.

for example, in trying to figure out what to attribute the big dip currently in 
the middle of the 
graph, I find that 'OK resort coffee...' is one of two things at the minimum 
point. 
The area covered by 'OK resort coffee' looks like it stretches over a long 
time, but it represents two 
data points just one day apart, 1/22 and 1/23/09.

However, the other series represented at the minimum point (bad office coffee) 
has an item more 
than two days away. So how is it that one series with two very close points 
looks so spread out in x 
but shares an x location with another series that is very far apart?

I imagine there's some amount of binning to keep a maximum number of horizontal 
data points, 
but it's a little confusing without knowing what the x axis really represents.

If I had to boil this down to a feature request it would be 'give me some way 
of seeing the x-axis in 
the stacked chart. a way to see what time particular data points came from 
would be great too, and 
even better would be zooming in or increasing the resolution so that individual 
data points have 
their own point on the graph.'

Thanks!
