I'd like to have the average of 2 y-values for 1 x-value

[RobertHoeke]

Hello,

I have acquired data from tests. The data is logged throughout a sweep. This means that for one X value I have got two Y values.

Does anybody know how to get the averages so I got one graph. The data is stored in one channel.

Thanks in advance.

Hello Robert,

Seems like the reduced loading of data channels could solve your request. If you choose 2 as "Intervall width" and Mean Value as "Reduction mode" you get a new channel with the means for each two values in the input channel. Either interactively from the short cut menue in the browser window of DIAdem NAVIGATOR or in a script using the command DataFileLoadRed.

Hope this helps,
Ralf

Hi Robert,

If your data are arranged such that multiple Y values for the same X value occur right next to each other, then Ralf's suggestion is ideal.  Are they arranged like this?

Y1 for X1
Y2 for X1
Y1 for X2
Y2 for X2
      :
Y1 for Xn
Y2 for Xn

If not, are the X values equidistant (equally spaced: 1, 3, 5, 7...)?
