Can't render numpy arrays

[GoogleCodeExporter]

What steps will reproduce the problem?

In [59]: import numpy
In [60]: l=numpy.array([1,2,3])
In [61]: g=GChartWrapper.LineXY(l)
In [62]: `g`

What is the expected output? What do you see instead?

I get the error:

---------------------------------------------------------------------------

ValueError: The truth value of an array with more than one element is
ambiguous. Use a.any() or a.all()

It seems it's trying to test the dataset by implicitly converting it to a
bool, but you can't do that with numpy arrays since the comparison is done
element-wise.

What version of the product are you using? On what operating system?

v 0.5 on a Fedora 8 x86_64 machine, python 2.5.1, numpy 1.0.3.1.

Please provide any additional information below.

hows about this:

        if 'any' in dir(self._dataset) and self._dataset.any():

Look to the new svn for this change
