Efficient view of large files

Status: Completed

Waiting for very large measurement files to load can take very much time. In our case, we sometimes load a file to have an overview of the complete measurement and then zoom into some specific parts of the measurement.

 

Idea:

Do not load into memory all data as long as the user has not zoomed in a specific area.

For example: if a channel has 100000 values, for a complete overview of the measurement, only 50000 values would be used. And when the user zooms in, then all data in that area will be loaded.

 

This way it is much easier to look for important parts in a measurement without waiting for all data to be loaded.

Hi Mex_J,

 

This is the exact behavior of DIAdem 2011 when dragging a TDM or TDMS data file into the Data Portal.  Note that it helps tremendously for those channels in the data file to have ALL the following channel properties already set:

 

Maximum

Minimum

NoValueKey

Monotony

 

You can  get the same dynamic loading behavior in previous DIAdem versions and/or with non-TDM/S data files by register-loading the data instead of dragging it into the Data Portal.
