title: Providing gradient colours for google chart api to draw pie chart
body: <p>I am using google chart APIs to draw a pie chart on the page. This uses some default colors to draw the sectors of the pie. We have an option to provide our own colors to draw the pie chart like <code>colors:['red','#004411']</code> as suggested in <a href="https://google-developers.appspot.com/chart/interactive/docs/gallery/piechart" rel="nofollow">https://google-developers.appspot.com/chart/interactive/docs/gallery/piechart</a>. Now I want to know how can I achieve some glassy effect by providing gradient colors to the APIs? Is there any way with which I cant achieve this?</p>
