	Betreff:	[mg23559] Reverse Axis

	Is there a way to reverse the axis on a 2-D plot?

	I am trying to flip the negative and the positive.

	
Dear Carl,

perhaps you may try out the following:

You may have plots

	p = Plot[BesselJ[0, x], {x, 0, 6 Pi}]

	p2 = Plot[BesselJ[1, x], {x, 0, 4 Pi}, PlotStyle -> Hue[0]]

Define

	ShowReflected[plots__, op_] := 
	  With[{g0 = FullGraphics[First[Flatten[{plots}]]], 
	      grest = Graphics /@ Rest[Flatten[{plots}]]}, 
	    Show[{g0, grest} /. {Line[pts_] :> Line[op # & /@ pts], 
	          Text[t_, coord_, offset_] :> Text[t, op coord, op
offset]}, 
	      PlotRegion -> {{0.05, 0.95}, {0, 1}}]]

and try

	ShowReflected[p, p2, {-1, 1}]

	ShowReflected[p, p2, {1, -1}]

	ShowReflected[p, p2, {-1, -1}]

(perhaps some time you need to tamper with PlotRegion)


Kind regards,  Hartmut
