does some one know how to get data from chart when the series is already hidden?

the case is i have chart with a lot of data (> 2years)  and when i do callback (SFX_SendUserCallback) to show some series which i hide before and do some scroll view then i want to get some point value to do calculation from the other hidden series. and I cant retrieve value of ChartFx.Data.Y from hidden series to have some statistic calculation on the fly...

this will improve performance to avoid many database connection...

 and the 2nd question is ... can i change Data.Y on some points and reflecting to chart?

 please help me... :) Thanks

1) If by hidding a series you mean doing:

chart.Series[i].Visible = false;

Then the series can be retrived with the Data API. The data API is unnafected by the Visible attribute of series.

2) Yes. You can change any value at any time.
