Plot

A Swiss Knife for displaying y[x] curves

Plot[expr_, {variable, min, max, step}, opts__]

has HoldFirst attribute. See the list of supported options (opts) down below.

You can zoom and pan any plots with a mouse. Right-click on the canvas to reset axes

Options

`PlotStyle`

Works as in Mathematica, i.e. per element in expr array, supports color, opacity and etc

Plot[Table[x^y, {y, 6}]//Evaluate, {x, 0,1}, PlotStyle->Table[Blend[{Red, Blue}, i/6], {i, 6}]]

`AxesLabel`

Place labels on your axes

Plot[Sinc[x], {x, 0, 10}, AxesLabel -> {"x", "Sinc[x]"}]

Labels accepts only strings or numbers unlike Mathematica, where you can put everything.

Since it is translated into Text, one can use sort of TeX math input

Plot[PDF[NormalDistribution[0, 1], x], {x, -10, 10}, AxesLabel -> {"wavenumber (cm^{-1})", "absorption \\alpha"}, PlotRange->Full]

It also supports absolute positioning using offset

Plot[PDF[NormalDistribution[0, 1], x], {x, -10, 10}, AxesLabel -> {"wavenumber (cm^{-1})", {"absorption \\alpha", {112,0}}}, PlotRange->Full]

`Ticks`

Customize ticks by providing an array of numbers for both axes

Plot[x, {x, 0, 1}, Ticks->{{0, 0.5, 1}, {}}]

Or by providing as pairs {Number, String} one can specify the displayed text

Plot[x, {x, 0, 1}, Ticks->{{{0, "Zero"}, {0.5, "Half"}, {1,"One"}}, {}}]

`Frame`

Turns plot into the journals-like styled graph. In general it has much more options to customize the look

Plot[x, {x, 0, 1}, Frame->True]

`FrameTicks`

The same as Ticks, but for this regime.

`FrameLabel`

The same as AxesLabel

Plot[x, {x, 0, 1}, Frame->True, FrameLabel->{
	"x-axis", 
	"y-axis"
}]

one can specify an absolute offset for a label by wrapping it into a list

Plot[x, {x, 0, 1}, Frame->True, FrameLabel->{
	"x-axis", 
	{"y-axis", {0,50}}
}]

`FrameStyle`

Affects the style of FrameLabels. Use Directive for changing the style

Plot[x, {x, 0, 1}, Frame->True, FrameLabel->{"x-axis", "y-axis"}, FrameStyle->Directive[FontSize->16]]

`FrameTicksStyle`

Affects the style of FrameTicks

Plot[x, {x, 0, 1}, Frame->True, FrameLabel->{"x-axis", "y-axis"}, FrameTicksStyle->Directive[FontSize->16]]

`TickLabels`

Since Plot options are hardcoded in WL core, we cannot add new options, however using trick with Insert any values can be provided to the resulting Graphics expression

To remove unnecessary ticks, use

Plot[x, {x, 0, 1}, Frame->True];
Insert[%, "TickLabels"->{{True, False}, {True, False}}, {2,-1}]

`ClippingStyle`

Show the clipped regions like the rest of the curve and colored

Plot[Sin[x]/x^2, {x, -10, 10}, ClippingStyle -> Red]

`Filling`

Fill the area under, over of between curves

Plot[Evaluate[Table[BesselJ[n, x], {n, 4}]], {x, 0, 10}, Filling -> Axis]

Possible options will be

Bottom
Top
{1 -> {2}} from curve 1 to 2

`Baseline`

Align graphs by the $x$ axis in each plot:

{Plot[Im[Zeta[1/2 + I t]], {t, -20, 20}, BaselinePosition -> Axis], 
 Plot[Re[Zeta[1/2 + I t]], {t, -20, 20}, BaselinePosition -> Axis]} // Row

`Epilog`

Puts any graphics object on top of the data plotted

Plot[Sin[x], {x, 0, 2 Pi}, Epilog -> {PointSize[0.04], Point[{0, 0}], Point[{Pi, 0}], Point[{2 Pi, 0}]}]

It opens up many possibilities, since it provides low-level access to the Graphics canvas.

`Prolog`

The same as Epilog, but acts before plotting the data.

`ExclusionsStyle`

Use red lines to indicate the vertical asymptotes

Plot[Tan[x], {x, 0, 10}, Exclusions -> {Cos[x] == 0}, 
 ExclusionsStyle -> Red]

`ImageSize`

A common option for any graphics

ImageSize -> Width

ImageSize -> {Width, Height}

It uses pixels as units

`MaxReqursion`

Affects the accuracy of the plot when it comes to the sudden changes of a sampled function

Plot[Sin[1/x], {x, 0.001, 0.1}, MaxRecursion->1]

The lowest values is 0

`Mesh`

Shows sampling points

Plot[Sin[1/x], {x, 0.001, 0.1}, Mesh -> All]

`PeformanceGoal`

Affects the number of sampling points to reduce the load

"Speed"
"Quality"

`PlotPoints`

Change the initial sampling points

a number

`PlotLegends`

Accepts Automatic, "Expressions" or List of expressions to show or explicit legend function, i.e. SwatchLegend, LineLegend or PointLegend

Plot[{Sin[x], Cos[x]}, {x, 0, 5}, 
 PlotLegends -> {"Sin", "Cos"}]

Plot[{Sin[x], Cos[x]}, {x, 0, 5}, 
 PlotLegends -> {Sin, Cos}]

Plot[{Sin[x], Cos[x]}, {x, 0, 5}, 
 PlotLegends -> SwatchLegend["Expressions"]]

Plot[{Sin[x], Cos[x]}, {x, 0, 5}, 
 PlotLegends -> SwatchLegend[Automatic, {Sin, Cos}]]


legend = PointLegend[{Red, Green, Blue}, {"red", "green", "blue"}];
Plot[{x, (*SpB[*)Power[x(*|*),(*|*)2](*]SpB*), (*SpB[*)Power[x(*|*),(*|*)3](*]SpB*)}, {x,0,3}, PlotStyle->{(*VB[*)(RGBColor[1, 0, 0])(*,*)(*"1:eJxTTMoPSmNiYGAo5gUSYZmp5S6pyflFiSX5RcEsQBHn4PCQNGaQPAeQCHJ3cs7PyS8qYgCDD/ZQBgMDnAEA4iUPRg=="*)(*]VB*), (*VB[*)(RGBColor[0, 1, 0])(*,*)(*"1:eJxTTMoPSmNiYGAo5gUSYZmp5S6pyflFiSX5RcEsQBHn4PCQNGaQPAeQCHJ3cs7PyS8qYoACKOODPVwEANd+D0Y="*)(*]VB*), (*VB[*)(RGBColor[0, 0, 1])(*,*)(*"1:eJxTTMoPSmNiYGAo5gUSYZmp5S6pyflFiSX5RcEsQBHn4PCQNGaQPAeQCHJ3cs7PyS8qYoACdMYHewDM1w9G"*)(*]VB*)}, PlotLegends->legend]

Legend placement

Use Placed to adjust the position of your legend, i.e.

Plot[
  {x,x^2}, {x,0,1}, 
  PlotLegends->Placed[SwatchLegend[Automatic], {0.2,0.2}]
]

`PlotRange`

Change the lot range to show the whole area

Plot[Sqrt[x], {x, -5, 5}, PlotRange -> Full]

Or a custom range

Plot[Sqrt[x], {x, -5, 5}, PlotRange -> {{-5,5}, {0,1}}]

`RegionFunction`

Show the specific area only

Plot[Sin[x], {x, 0, 8 Pi}, RegionFunction -> Function[{x, y}, Abs[y] > 0.5]]

`Axes`

Show or hide axes of the plot

Plot[Sinc[x], {x, 0, 10}, Axes -> False]

Interactivity

Consider to use ManipulatePlot for manipulating parameters of a function in real time
