vertical scale

[marco.giordano]

Hi all,

first of all, many compliments for your work!!
I don't know if the feature I'm looking for is better related to Sonic Visualizer or libxtract plugin... so I try here first.

I'd like to fix vertical scale of panes so that all the features I include in that pane refer to the same scale.
E.g. suppose I want to compare in one pane the same feature extracted from different sound samples. It would be better to have them plotted on the same scale, but each time I switch layer I see that SV modifies the vertical scale according to the min-max range of values.

Is there a way to accomplish this?

Many thanks and regards

Marco

Marco,

Which sort of layer are you dealing with?  Time-value plots, grids,...?

The intention is that the Auto-Align setting for a layer's vertical scale property should do what you ask -- but only if the layers that you want to have aligned to the same scale all share the same (non-empty) scale unit.  If the layers were generated by running a plugin that declares unit(s) for its output(s), then that should be the case already.  Otherwise, you should find that if you set the layers to Auto-Align and enter some unit text in each layer's Unit setting -- the same text for each layer that you want to line up -- then it does as you would expect.  (Note that you have to hit Return after entering a new unit into the text box for that setting.  It's actually a combo box with a menu, which remembers the units that you have already used so you can select them again quickly.)

Hope this makes sense!  Let me know if you have problems with it.

Hi Chris,

 

I'm blushing for my silly question but I really didn't realize I could write the full scale value in the 'Scale Units' box!!!!
I assumed it was just a select box ...... 

Many thanks

Marco
