dB-axis

Which is the easiest way to get a dB-Y-axis (for example 20*log(y/yref)??

I found no option in the properties for axes to switch from absolut-values to dB-values.

If there is no, a proposal for next updates could be the following:

A new item in properties for y-Axis with option “dB” . The user have to input a reference-value for the specified datas and the factor to multiplicate with (“20” e.g.)………

You can scale your data in an easy way. Create a formula named “_Scaled” with the following content:

Arguments data
Dim yref

yref = 1
20*log10(data/yref)

You can now scale your data sets by selecting them in the FlexPro Explorer and simply dragging and dropping them onto the name of the above formula. FlexPro then creates a new object for each dataset which returns the scaled data and whose unit is set to “mA”.

Thanks….

That’s the way i do it till now.

It should be only a property of axes (like “log, ln, lin, octave” etc.) . No calculation of data in
additional rows of the sheet….
