keep zoom level when switching

[sdavey]

we would like to be able to switch chromosomes (refseqs) without changing the zoom level. Is there an option already to do this? If not, can one please be added?

Unfortunately, not that I'm aware of. It seems there are some inherent functional properties of the implementation that suggests there may be a number of corner cases to deal with.

Noted.

For Apollo, the plugin over-rides the onResize function to deal with this. I can point you to that code if you want to write your own plugin.

thanks for the suggestion. I found the code at https://github.com/GMOD/Apollo and will take a look.

You can try here:

https://github.com/GMOD/Apollo/blob/master/client/apollo/js/main.js#L219 https://github.com/GMOD/Apollo/blob/master/client/apollo/js/main.js#L219

Though there might be better ways to do this, as well.

Also, I had a problem with some customizations I was making and had to add this after that code. Again, not sure if it was the best way, but it worked:

    browser.afterMilestone( 'completely initialized', function() {
        var view  = browser.view ;
        var projectionString = view.ref.name ;
        var projectionLength = window.parent.getProjectionLength(projectionString);
        var ratio = view.elem.clientWidth  / projectionLength  ;

        browser.view.pxPerBp = ratio ;
        browser.view.onResize();
    });

This is an interesting one, because I can see how some users might want this behavior, but others might not. This sounds like a good idea for a plugin.
