zoom the Yaxis

[ashfliu]

I want to zoom the Yaxis according the acquired datas.if the amplitude of data is small,then i can click one end of the Yaixs to shrink the range,and if the amplitude is large,then i can also click the another end of the Yaixs to enlarge the range.so how can i get it？

You have to align all the Yaxis nodes according to their size and scaling otherwise one node would be larger than another, you could use some program to do it rightly.
