# Fix range when combining plots [duplicate]

Is there a way to automatically choose the y-axes when combining plots (and in passing, why isn't that the default behaviour for Show[ plot1, plot2 ]?)

 bidPlotZoom    = Plot[ bid[u], {u, 0, 20000 }, PlotStyle -> Blue ]
askPlotZoom    = Plot[ ask[u], {u, 0, 20000 }, PlotStyle -> Green ]



Actually I'd settle for a manual way right now :)

• Somehow WRI decided to mention that not earlier but in the last section of docs for Show. Show takes options from the first graphic.

• Thanks. Still wondering why PlotRange -> Automatic isn't the default, but I'm sure there is a reason. Dec 9 '14 at 5:47
• yup, that would be a duplicate Dec 9 '14 at 8:11

Show[  , PlotRange-> Automatic ]
