Dear Bence and Joe，
Recently, when I used iolite software to check the signal distribution of different elements and tried to export it, I found that the ordinate can only be based on one of the elements as a reference, and the signal of the other elements could not be reflected on the ordinate, that is to say, Different elements are not a uniform coordinate range，as the picture shows：https://imgur.com/ixJGJS0 The ordinate is only the change in the count value of Fe, the changes of the rest of the elements are exaggerated in this picture, including the background value, I need them to be unified to one scale, as shown in this picture：https://imgur.com/nYHWEmj，I don't know how to do it in software so that all elements are in the same ordinate 
signal graph display problem
The y-axis will show whatever the first selected channel is. All other channels that are displayed will use the range that is stored for them. If you want to plot them all with the same range, you can select all the channels and click "Manual" then enter the range you want them to plot between. Now all channels should be plotted in the same range. The axis label will still be whatever the first selected channel is though.
All the best,

Joe Thank you, I get it, 
but I think iolite can do a better job of unifying the coordinates of all elements, after all, after selecting an element, zooming in or zooming out a little and the coordinates are not uniform will make some elements actually low but look very High illusion, if we don't always pay attention to the ordinate
We've intentionally made it so the channels are not unified in the time series view. For example, viewing a U-Pb ratio/age and a concentration on a unified scale does not make sense. Basically any combination of channels that are not in the same units does not make sense at all, and only in some circumstances does viewing channels of the same units on the same scale make sense (e.g. a major and trace on the same scale is only useful if logarithmic).
That said, I'll see if I can work in an option to plot everything on the same scale.
All the best,
- Joe
Joe Yes Joe, you're right. I usually view the channels in the case of logarithmic coordinates. If such a picture is displayed in the article, it may be necessary to have a unified coordinate scale 
I definitely agree that the time series view way of showing things would not make sense for a figure in an article. However, I would say the time series view isn't the best place to make such a figure. You can have much more control about what is plotted, how it is plotted, and the style if you use Tools->Custom Plot or write a small python script to create a figure (see examples on our notes site).
All the best,
- Joe
Joe Ok thank you Joe, I'll take the time to learn about it
