# Omit part of a 2D plot [duplicate]

I am interested in removing a part of my plot, after searching around I could not find any questions concerning this problem. To illustrate it consider the following minimum working example:

f[x_] = (\[CapitalGamma]/2)/(x^2 + (\[CapitalGamma]/2)^2);
g[x_] = f[x - \[Nu]Clock];
Settings = {\[CapitalGamma] -> 5.2(*MHz*), \[Nu]Clock -> 9000};
plot1 = Plot[{f[x] /. Settings, g[x] /. Settings}, {x, -500, 9500},
Frame -> True, PlotRange -> Full]


Plotting it is seen that there is a huge part (200 < x <8200) where the plots are just zero. I would like to remove this part of the plot. I can also accept a solution where I make the two plots separately and then combine them use GraphicGrid but I am still unsure of how this would work.

• @SimonWoods Indeed this looks to be a duplicate. The only difference is that in that question the two plots needed to be shifted vertically and here horizontally. Aug 11, 2012 at 20:46

I took some liberties with the plotting, trying to figure out what you really wanted. g(x) is a simple translation of f(x) over x so it's no wonder that the curves look identical.

Here's a side-by-side rendering.

Settings = {\[CapitalGamma] -> 5.2(*MHz*), \[Nu]Clock -> 9000};
f[x_] = ((\[CapitalGamma]/2)/(x^2 + (\[CapitalGamma]/2)^2)) /.Settings;
g[x_] = f[x - \[Nu]Clock] /. Settings;
plot1 = Plot[{f[x], g[x]}, {x, -200, 200}, Frame -> {{True, False}, {True, True}},
PlotRange -> {Full, {0, .1}}];
plot2 = Plot[{f[x], g[x]}, {x, 8800, 9200}, Frame -> {{False, True}, {True, True}},
PlotRange -> {Full, {0, .1}}];
GraphicsGrid[{{plot1, plot2}}]


Here's a way to show the discontinuity along the x-axis, based on Heike's torn image technique:

For this case, I tweaked the AspectRatio and BaseStyle:

plot1 = Plot[{f[x], g[x]}, {x, -200, 200}, AspectRatio -> 1.4, BaseStyle -> 24, Frame -> {{True, False}, {True, True}}, PlotRange -> {Full, {0, .1}}]
plot2 = Plot[{f[x], g[x]}, {x, 8800, 9200}, AspectRatio -> 1.4, BaseStyle -> 24, Frame -> {{False, True}, {True, True}},  PlotRange -> {Full, {0, .1}}];


The torn commands are:

t1 = torn[left, {{0, 1}, {0, 0}}, "offset" -> {20, 20}, "gaussianBlur" -> 10]
t2 = torn[right, {{1, 0}, {0, 0}}, "offset" -> {20, 20}, "gaussianBlur" -> 10]


where left and right are images of plot1 and plot2.

The final image is simply:

Row[{t1, t2}]


You can adjust the details to your own liking. You'll need to download the torn code and read the explanation here.

• And in one plot? Because I think that's what OP wants. Aug 11, 2012 at 18:24
• I rearranged them side-by-side. Not exactly in a single plot. Aug 11, 2012 at 18:40
• Hey guys thanks for the answers, first things first: 1) The idea is to remove the plot altogether as it has been done in the second answer 2) Yes at the moment the two curves are just a translations but in the end they will be scaled differently in amplitude and FWHM, but altogether the same order of magnitude. I can surely accept (as I wrote) the solution with the graphics grid but had hoped there where someway around it, but think I will go for it. Thanks for the help..
