Hey there. I am having a funny time trying to fix the second y axis on the following page.

[http://ics-webread01.esss.lu.se/](http://ics-webread01.esss.lu.se/)

What I want is the range to autofit every few seconds, and then become fixed, but is not working for y axis 2.

intial parameters:  
yaxis2: {  
title: ‘Proton Rate’,  
titlefont: {color: trace2Color},  
tickfont: {color: trace2Color},  
overlaying: ‘y’,  
side: ‘right’,  
fixedrange: true

```
            },

```

Update code that runs once every 42 frames :

if ((PVFrame[PVNames][traceNum] == 2) || (updatePlots==true)) {  
var update = {  
‘xaxis.autorange’: true,  
‘yaxis.autorange’: true,  
‘yaxis2.autorange’: true,  
};  
Plotly.relayout(plotName, update)  
updatePlots==false;  
}  
else if ((PVFrame[PVNames][traceNum] == 3)) {  
var update = {  
‘xaxis.autorange’: false,  
‘xaxis.fixedrange’: true,  
‘yaxis.autorange’: false,  
‘yaxis.fixedrange’: true,  
‘yaxis2.autorange’: false,  
‘yaxis2.fixedrange’: true,  
};  
Plotly.relayout(plotName, update)

Thanks for any and all insights. 🙂

Can you clarify what you mean by _fixed_

Fixed as in:

- does not auto-range as new data comes in, or
- users can no longer zoom about this particular axis?
