Doc forthcoming?

[Ben]

Pie chart documentation looks right at first sight, including
configuration options and stuff. But at second sight I think it it
completely unclear on how for example configurations options can be
used. So although documented one would still be unable to use the
configuration options, even when looking at examples because it is
completely unclear what the signature is of for example of the draw
method. Do you need to pass options there? How?

Easy tasks become hard to the point of making the API unusable. For
example. How to make the background transparent (why is not
transparent in the first place)? Google for it, read pie chart
documentation and come up with absolutely nothing useful.

The charts are rather thoroughly documented (although errors do occasionally crop up).  Since you bring up Pie Charts, I'll use them as an example:

Create a DataTable as documented here:

http://code.google.com/apis/chart/interactive/docs/reference.html#DataTable

Pie Charts require data to be presented as two columns, as documented here:

http://code.google.com/apis/chart/interactive/docs/gallery/piechart.html#Data_Format

Pie Chart configuration options are documented here:

http://code.google.com/apis/chart/interactive/docs/gallery/piechart.html#Configuration_Options

Pie Charts are drawn with the PieChart#draw method, as documented here:

http://code.google.com/apis/chart/interactive/docs/gallery/piechart.html#Methods

Options are passed to the draw function as an object, documented here:

http://code.google.com/apis/chart/interactive/docs/reference.html#visdraw

If all of this isn't clear, there is the visualization playground here:

http://code.google.com/apis/ajax/playground/?type=visualization#pie_chart

which allows you to experiment with the API and figure out how all the API's components work together.  If that still doesn't help you, then perhaps we can offer some assistance.

There are some things that the API cannot do, and AKAIK, making the background transparent might be one of them.  Some limitations can be hacked around, others cannot (at least, not easily).

As for your "why isn't it transparent by default" question, it's because we couldn't make transparent work for IE...

Google for it, read pie chart
