[Matplotlib-users] RE: matplotlib questions

[Ted D. <ted...@jp...>]

We have some data that we'd like to plot and I'd like to know if matplotlib 
(MPL) supports this directly (I don't think it does) or where we should 
start looking to implement this capability.

We want to plot time intervals in a similar way to a horizontal bar 
graph.  In this case, the data is when a spacecraft is in view of a ground 
station.  So for a list of ground stations (the y axis), we have lists of 
start and stop times that represent the view periods.  So we need to:

- show the list of ground stations (i.e. arbitrary labels) along the Y axis 
like you would on a bar chart.

- draw sets of rectangles at the right y location with the length 
determined by the x data (in user controllable line styles, colors, and fills).

- optionally label the start and stop points of each interval with the X 
value for that point (in this case a date/time).  Ideally, the user would 
have the option of specifying a location relative to the bar for each end 
point like this (none, high, mid, low):

High              High
     |-----------|
Mid |    BAR    | Mid
     |-----------|
Low               Low


I don't think I can currently do this in MPL so I'd like to here ideas from 
John and anyone else on which classes I should start looking at any 
suggestions on how this should work.

Thanks,
Ted
