thanks a lot for the code,great project and helped me a lot. I was trying to change the data dynamicaly for the chart. For example I want to implement pinch to zoom on the lineseries and change the data dynamically. when I change the itemsources of the lineseries the old data is still been plotted. How to get rid of the same.
