Google-chart interacting

[skalde...@gmail.com]

Hey guys,

I am using a google-chart-element (type bar) in my application and wanted to do the following:

When the user clicks on a bar, I want to switch the colour from the current one to grey

I tried doing this by handling the on-google-chart-select event, in which i modify the data

array of the chart at the respective position to the new colour

This lead to two problems:

1. The select event seems to be always fired twice ... annoying, but fixable

2. I could change the correct colour value in my data array to the new colour, and then I wanted

    to redraw the chart, so that the clicked bar now shows the grey colour

    So I used drawChart() - method, which did not lead to the desired result

The select event was fired 5 or 6 times after using drawChart() (??) and the colour was not updated

But the data array contained the correct colour value at the correct position...

What am I missing here?
