AreaChart not updating

I have an area chart that shows my revenue from sales over the months. The area chart is initialized with dummy values but gets updated with the real values at page load. When I hover at any part of the chart I can see the correct value but the line is still plotted on the old data. Once I resize my window the line gets updated. How can I force it to update? I tried this.forceUpdate() but it doesn't work.
