如何在Mathematica的Manipulate面板中定位和调整输出？

Question

以下代码允许您使用惠斯通电桥中的值.输出显示在滑块右侧.如何使输出面板(expr)出现在其他位置,如何设置固定大小？(我只能找到操作控件的大小和位置的选项,而不是Manipulate文档中的输出.)

Manipulate[
 Evaluate[(10^Rx/(10^R3 + 10^Rx) - 10^R2/(10^R1 + 10^R2))*Vin] "V",
 {{R1, 5}, 1, 6, 0.01},
 Pane["R1  = " Dynamic[Round[10^R1] "\[CapitalOmega]"], 
  ImageMargins -> {{2.5, 0}, {3, 0}}], {{R2, 5}, 1, 6, 0.01},
 Pane["R2  = " Dynamic[Round[10^R2] "\[CapitalOmega]"], 
  ImageMargins -> {{2.5, 0}, {3, 0}}], {{R3, 5}, 1, 6, 0.01},
 Pane["R3  = " Dynamic[Round[10^R3] "\[CapitalOmega]"], 
  ImageMargins -> {{2.5, 0}, {3, 0}}],
 {{Rx, 5}, 1, 6, 0.01},
 Pane["Rx  = " Dynamic[Round[10^Rx] "\[CapitalOmega]"], 
  ImageMargins -> {{2.5, 0}, {3, 0}}],
 {{Vin, 2.5}, 0, VMax, Appearance -> "Open"}]

好吧,如果您可以根据内容框定位控件,那么您也可以将内容框放在控件上,不是吗？

所以,ControlPlacement应该注意你的盒子的位置,并把它放在一个Pane小心的尺寸(ImageSize虽然它似乎从控件尺寸看它的最小尺寸).

VMax = 12;
Manipulate[
 Pane[ToString[(10^Rx/(10^R3 + 10^Rx) - 10^R2/(10^R1 + 10^R2))*Vin] <> 
   "V", ImageSize -> {500, 20}], {{R1, 5}, 1, 6, 0.01}, 
 Pane["R1  = " Dynamic[Round[10^R1] "\[CapitalOmega]"], 
  ImageMargins -> {{2.5, 0}, {3, 0}}], {{R2, 5}, 1, 6, 0.01}, 
 Pane["R2  = " Dynamic[Round[10^R2] "\[CapitalOmega]"], 
  ImageMargins -> {{2.5, 0}, {3, 0}}], {{R3, 5}, 1, 6, 0.01}, 
 Pane["R3  = " Dynamic[Round[10^R3] "\[CapitalOmega]"], 
  ImageMargins -> {{2.5, 0}, {3, 0}}], {{Rx, 5}, 1, 6, 0.01}, 
 Pane["Rx  = " Dynamic[Round[10^Rx] "\[CapitalOmega]"], 
  ImageMargins -> {{2.5, 0}, {3, 0}}], {{Vin, 2.5}, 0, VMax, 
  Appearance -> "Open"}, ControlPlacement -> Bottom]

编辑更改[CapitalOmega]到\[CapitalOmega].谢谢Belisarius.
