Hi,
How do I calculate:
Average
Standard Deviation
Max
Min
from a serie ?
If I "zoom" on a part of the serie - how do I then calculate the average, standard deviation and max and min of only the part that has been zoomed ?

You can use TeeChart built-in functions for that. You'll find examples of all of them at
All Features\Welcome!\Functions\ in the new features demo, available at TeeChart's program group.

For minimum and maximum you could do something as the local minimum and maximum example suggested
here. You could use series' FirstVisibleIndex and LastVisibleIndex as first and last arguments. This is a TeeChart .NET thread but same should apply to VCL version.
For average and standard deviation you could use its
Calculate method passing visible indexes as in the local minimum and maximum example.
