Forcing labels and ranges in order means no random access.

[GoogleCodeExporter]

Say I want to have 3 axis labels: x,y,t to include a top label.

And suppose I'm happy with the API's default labelling for x and y, as
values, but want to change "t" to something else. I can only get to the
third axis if I specify labels for the first two, then the third target
axis in order.

With scaling and other such features, it might be tricky to re-manufacture
the automatic label text.

With the "raw" API one can indicate which axis one wants to mess with:

&chxl=2:|my label is here&...

Here's a full example of a chart that can't be currently done with the wrapper:
http://chart.apis.google.com/chart?chxt=x,y,t&chds=0,100,0,10&chd=t:0.0,5.0,25.0
,50.0,75.0,100.0|0.0,0.3,1.3,2.3,3.3,4.3&chxr=0,0,100|1,0,0.393700787402&chs=300
x150&cht=lxy&chtt=Title&chxl=2:|my+label+here&chxp=2,50

This sort of in-order-only pattern is common in the wrapper.

You still can set the 'raw' api params via the dict instance or kwargs

G = LineXY(dataset, chxl='2:|my label is here&...')

and renders w/ no questions asked. 

Thank you so much for trying to poke holes in the module, and im sure there is a
better way to do this. If you could show programatically how u would like to 
achieve
this using the wrapper ANY OTHER WAY, i would be happy to view it.

Excellent.

I didn't know that capability was present. (maybe an example or some docs would 
help
that ; wink wink).

As far as other ways to do it, I think your way (in order) could stay the 
default,
but perhaps an optional index argument could be passed.

Thanks again.

Actually this still doesn't work.

Either you can just skip your wrapper and send in __init__ args, as you 
suggest, OR
you can use the wrapper.

What if I want to use the wrapper but don't want to specify in order?

Here's a more thorough example...

gc = GChart('lxy', ([0,1,2,3,4,5], [0.1, 0.2, .05, 0.3, 0.5, 0.2]))
gc.scale(0,6) # sets the X scale
gc.scale(0,10) # sets the Y scale
gc.axes.type('xytr') # sets up four axes
gc.axes.range(0,60) # sets the scale on the labels; we want to KEEP these 
auto-labels
gc['chxl'] = '2:|my label here' # doesn't show up in output
gc['chxl'] += '2:|my label here' # KeyError

After much thought and deliberation I have decided to implement assigned 
indexing for
axes functions. Here is what has changed in v0.8

{{{
# Old Way
>>> G.axes.type('xy')
>>> G.axes.label('Mar','Apr','May')
>>> G.axes.label(None,'50+Kb')

# New Way
>>> G.axes('xy')
>>> G.axes.label(0, 'Mar','Apr','May')
>>> G.axes.label(1, None,'50+Kb')
}}}
