When I resize the window, all the chart elements were resized, but the legend items and the y-axis labels does not change their size (the font-size). Is there a way to make the chart gets resized uniformly?
The X-Axis labels size is changed but not the y-axis and legend items font size.
If you want the chart to resize uniformly almost as if it were an image of a chart, you could experiment with using something like the ViewBox control from the Silverlight Toolkit. Or you could apply a render transform to the chart. Also, as you can adjust the font sizes used in the chart, you could try and scale these values as the available area changes yourself.

Thank you, the Viewbox tip helped.
