Hi Mohamed,

I think you are already aware there is an example "Interactive Finance Chart" included in CharrtDirector that can draw charts with variable sizes, create intraday or interday charts, and change the indicators, etc... The code structure is as follows:

(a) Create a drawChart subroutine to draw the chart based on the current user selection (the state of the user controls)

(b) If the user control changes (changing the size, selecting different date range, technical indicators, etc), just call drawChart again.

(c) If new data come in (realtime chart), update your data arrays (eg. append data to the arrays), then call drawChart again.

Hope this can help.

Regards
