Hello there:

First of all i like to congratulate to developrs who made this great solution. Thanks a lot. 

Second i followed the example to display a pie chart successfully, it loads correctly and thats ok. After that i've deployed the same code to display ina web page that is child of a master page.

when it loads the first time(is not postback), it diplays correctly, a pie chart with its series, and whole colors. but when i raise a postback event (in this example a dropdown_selectedindexchanged event) i load new data to the chart and then the chart only displays its series, without a pie inside it. (i mean the circle with all its slices).

i've tried with an update panel, not worked. then with a Place holder adding a new PieChart control to it, also not worked.

if anybody have a functional solutions i'll appreciate it.

P.D. sorry for my english, i'm a bit rusty.
