title: How to apply flat colors effect in Kendo charts
body: <p>I am using Telerik charts in my project. I am able to change the color of charts but not the style. What i mean by style is - there appears a embossed effect over all the charts(First Image). What i need to apply is flat colors(Second Image). How can i remove gradient effect over charts in all my Kendo charts?</p>
