Something like 'legend = :topright' might work.

Is it possible to position the legend manually in a plot(x,y,leg_pos=???)

Re: [julia-users] @animate @gif using plots

[digxx]

Sorry again, not quite the same error:
He was using ffmpeg apparently. Though I got it working with convert now 
(after removing all the imagemagick packages from julia and with the 
manually installed stuff) what is remaining is the jumping legend also seen 
in the above uploaded gif.

So same error as before but apparent afterwards he still is able to use the 
installed version to convert it?
The .gifs look pretty weird though:

Yes I did and it still persists :-(
I added and removed various Packages to see if sth is missing (comparing to 
before)
but nothing works :-(
I removed and readded Imagemagick but that also didnt help.

[Tom Breloff]

Did you restart julia after adding ImageMagick?  The errors are because it
can't find either ImageMagick or ffmpeg, one of which is required to make
gifs.
