Comprehensive guide to manipulating axes in idl

I am trying to have 4 plots in the same window using

    !p.multi=[0,2,2]
    !p.position=[0.11,0.5,0.5,0.9] ...some code
    !p.position=[0.5,0.5,0.9,0.9] ...some code
    !p.position=[0.11,0.1,0.5,0.5] ...some code
    !p.position=[0.5,0.1,0.9,0.5] ...some code

The position of the plots is perfect (see graph here) but

a/ I would like to remove the scale on the x axis in the top 2 plots and have it at the top of the top plots rather than at the bottom.

b/ I would like to have the y axis on the right of the 2 plots on the right rather than on their left.

I have managed to do this kind of plot in the past but after hours playing with the [xy]style and axis commands. Part of the problem is that I can't find a comprehensive guide on the internet which would simple break down each style such that

xstyle = 1 ;definition

xstyle = 2 ; definition

...you get the jist of it.

Would somebody be able to refer me to a good guide on how to manipulate axes in idl so that I don't have to guess the styles each time I have to plot. If not, would somebody be able to break down the style and axis options / commands very simply on stack overflow? I doubt I'm the only one stumbling upon this problem time and time again...?

Thank you very much!

If you want to draw an axis on the "opposite side", you need to suppress the axis (i.e., [XY]AXIS=4) and then make the axis yourself in the correct location with the AXIS command.

The online help has definitions for the values of XSTYLE and the options to AXIS.
