Dynamic Graphs?

vrysin · November 24, 2005, 3:33am

Hi,

Is it possible to draw a moving graph. e.g. a sliding window of 100 values from a large dataset (10000 values) updated every two seconds?

Many thanks,
Vlad

I ran a script of a “moving” TGraph and I noticed it was leaking memory. I tried deferent ways – same thing. Then I tried seism. It was leaking memory too. One run of seism grabs about 15MB of memory. Neither ->Reset() or delete help.

I run ROOT on Windows XP. I believe it is not a tier 1 platform for ROOT but I think it is not Windows this time.

Any ideas?

Thanks,
Vlad

I do not see any leak at all with seism.C.
You must be using a very old version.
Please always indicate which version you are using when posting to the Forum.

PS: Windows is a supported platform.

Sorry about version and other info information.

I run root v4.04.02

I included two files:

log of gObjectTable->Print(); before and after seism run
CPU and memory graph of root process as I run seism.

Thanks,
Vlad
