select a range of data

[M.Charbonneau]

Hi everyone,

I would like to know how to do to select a range of data (for example on a force/time graph during a jump landing (parable), from a certain value to another) to register it on a special file? I tried the module "separate" or "cut out" but I don't think they will be useful when you don't know when will appear the specifical value you're looking for...

Is it also possible in Dasylab to know the director coefficient of this type of curve (quite linear...)?

Thanks!

Please look at the Trigger module group. Use the trigger to select the range and the Relay to remove the data until the trigger is detected.

There are at least two trigger examples in the DASYLab Help->Examples. Please review them for hints on how to configure the triggers. 

I'm not sure I understand your second question... are you looking for the Regression module?

Can you give us some graphs of what you're trying to do?

I also would encourage you to look into DASYLab classes in your area

here you are the type of curve I found. I need to find the coefficient director of the line between A and B (formula : (Yb-Ya)/(Xb-Xa). I guess that first, I have to use the regression module between the 2 points and then... How can I do? It's easy on Excel but I'll try to use only dasylab... 🙂

Yes, I'll suscribe to dasylab classes if they make vouchers 😉

Perhaps...

Select the values in a block (y values) at given positions (y values).

Calculate the differences, and calculate the quotient.
