plotting - Combine Plots into a single non-rasterized Graphic with no spacing



Suppose that I have two plots, pl1 and pl2:


pl1 = Plot[x, {x, 0, 1}, Frame -> True, ImageSize -> 350]
pl2 = Plot[x^2, {x, 0, 1}, Frame -> True, ImageSize -> 350]

pl1


pl2


I would like to (1) combine these plots side-by-side in a (2) non-rasterized graphic with (3) no spacing.


I get pretty close to my desired result by using Grid with Spacings -> 0:



Grid[{{pl1, pl2}}, Spacings -> 0]

grid


The above satisfies my requirements (2) and (3): the result is non-rasterized, and there is no spacing between the plots. However, the above doesn't satisfy my requirement (1), that the plots be combined into a single Graphic object. That is, if I click on either of the plots, I see that they are separate Graphic objects:


gridA


gridB


So the above approach doesn't satisfy all of my requirements. (Why do I need the plots to be combined in a single Graphic? The reason is that I want to be able to place other Graphic objects -- e.g., text, arrows, shapes, etc. -- that span the two plots.)


Another possibility is to use ImageAssemble, but unfortunately this leads to a rasterized image:


ImageAssemble[{{pl1, pl2}}]


imageassemble


A third possibility is to use GraphicsGrid with Spacings -> 0:


GraphicsGrid[{{pl1, pl2}}, Spacings -> 0]

graphicsgrid


It seems that this produces a single Graphic object ((1)) that is not rasterized ((2)), but, unfortunately, there is spacing between the plots.


Do you have any suggestions? Is there any way to remove the spacing/padding in GraphicsGrid?



Answer



You could do something like the following:


pl1=Plot[x,{x,0,1},Frame->True,ImageSize->350, 

 ImagePadding->{{Scaled[0.05],None},{Automatic,Automatic}}];
pl2=Plot[x^2,{x,0,1},Frame->True,ImageSize->350, 
 ImagePadding-> {{None,Scaled[0.05]},{Automatic,Automatic}}];

GraphicsGrid[{{pl1,pl2}},Spacings->{Scaled[-0.07],0}]

enter image description here


This removes the padding from the graphics themselves with the option ImagePadding, and a magic number of -0.07...There is likely a better way.

front end - keyboard shortcut to invoke Insert new matrix

I frequently need to type in some matrices, and the menu command Insert > Table/Matrix > New... allows matrices with lines drawn between columns and rows, which is very helpful. I would like to make a keyboard shortcut for it, but cannot find the relevant frontend token command (4209405) for it. Since the FullForm[] and InputForm[] of matrices with lines drawn between rows and columns is the same as those without lines, it's hard to do this via 3rd party system-wide text expanders (e.g. autohotkey or atext on mac). How does one assign a keyboard shortcut for the menu item Insert > Table/Matrix > New... , preferably using only mathematica? Thanks! Answer In the MenuSetup.tr (for linux located in the $InstallationDirectory/SystemFiles/FrontEnd/TextResources/X/ directory), I changed the line MenuItem["&New...", "CreateGridBoxDialog"] to read MenuItem["&New...", "CreateGridBoxDialog", MenuKey["m", Modifiers-...

mathematical optimization - Minimizing using indices, error: Part::pkspec1: The expression cannot be used as a part specification

I want to use Minimize where the variables to minimize are indices pointing into an array. Here a MWE that hopefully shows what my problem is. vars = u@# & /@ Range[3]; cons = Flatten@ { Table[(u[j] != #) & /@ vars[[j + 1 ;; -1]], {j, 1, 3 - 1}], 1 vec1 = {1, 2, 3}; vec2 = {1, 2, 3}; Minimize[{Total@((vec1[[#]] - vec2[[u[#]]])^2 & /@ Range[1, 3]), cons}, vars, Integers] The error I get: Part::pkspec1: The expression u[1] cannot be used as a part specification. >> Answer Ok, it seems that one can get around Mathematica trying to evaluate vec2[[u[1]]] too early by using the function Indexed[vec2,u[1]] . The working MWE would then look like the following: vars = u@# & /@ Range[3]; cons = Flatten@{ Table[(u[j] != #) & /@ vars[[j + 1 ;; -1]], {j, 1, 3 - 1}], 1 vec1 = {1, 2, 3}; vec2 = {1, 2, 3}; NMinimize[ {Total@((vec1[[#]] - Indexed[vec2, u[#]])^2 & /@ R...
