How to create dataset with constant time step from dataset with random time step

[alpir]

Hello,

Could you tell me if it possible to solve folowing problem in DIAdem?

We have dataset with pairs of temperature and time of measurements, but time step is random. It's look like:

time:   1 min     3 min    7 min    8 min    8.5 min     13 min    17 min  .....

temp:   3          4          10         11        15             4            6     .....

We need to have approximated values of temperature with certain time step (for instance, 1 min). So, it have to be like this:

time:   1 min     2 min    3 min    4 min    5 min     5 min    7 min  .....

temp:   3          3.5        4          4.5        5           7           10     .....

Thank you in advance very much!

Hi Alexey,

Sure, the function you're looking for is in the ANALYSIS panel under the "CUrve Fitting" palette-- it's called "Linear Mapping".  You will need to create the desired X channel prior to calling this function, though, so you will probably need to use the ANALYIS function "Generate Numeric Channel" in the "Channel Functions" palette.
