How to create a barometer?

How do I make a barometer, which fade from red to blue? ( I also need a glass effect to it)

you sure you mean barometer? there would be no reason to do a color fade in a barometer, since it is a clock-like looking piece with hands and numbers. but use a gradiant tool for your color fade.

Do you mean this:

Just pick 2 colors, then click on Gradient Tool then at the top click on Angle Gradiant and hold and drag the mouse (making a line) where you want it to go.

I mean a barometer like this one

(This one is just to ugly)


It have to be red at the top and blue at bottom.

wrong url?

just make a shape with rectangular marquee and then make edit>stroke and use 1 pixel. so it has a shape and then use a gradient!

oh the little scientific ones. i thought you were refering to the recent barometers..

Hey! I remember all that stuff from Chemistry class. Boyle's law, Charles' law... Oh memories.

Oh, as for the barometer... I don't know how to make one.

Its not a problem to make the shape, but its more difficult to create the glass effect.
