Plot
Plot[f,{x,x_{min},x_{max}}]
generates a plot of f as a function of x from x_{min} to x_{max}.
Plot[{f_{1},f_{2},…},{x,x_{min},x_{max}}]
plots several functions f_{i}.
Plot[{…,w[f_{i}],…},…]
plots f_{i} with features defined by the symbolic wrapper w.
Plot[…,{x}∈reg]
takes the variable x to be in the geometric region reg.
Details and Options
 Plot evaluates f at different values of x to create a smooth curve of the form {x,f[x]}.
 Gaps are left at any x where the f_{i} evaluate to anything other than real numbers or Quantity.
 The limits x_{min} and x_{max} can be real numbers or Quantity expressions.
 The region reg can be any RegionQ object in 1D.
 Plot treats the variable x as local, effectively using Block.
 Plot has attribute HoldAll and evaluates f only after assigning specific numerical values to x.
 In some cases, it may be more efficient to use Evaluate to evaluate f symbolically before specific numerical values are assigned to x.
 The following wrappers w can be used for the f_{i}:

Annotation[f_{i},label] provide an annotation for the f_{i} Button[f_{i},action] evaluate action when the curve for f_{i} is clicked Callout[f_{i},label] label the function with a callout Callout[f_{i},label,pos] place the callout at relative position pos EventHandler[f_{i},events] define a general event handler for f_{i} Hyperlink[f_{i},uri] make the function a hyperlink Labeled[f_{i},label] label the function Labeled[f_{i},label,pos] place the label at relative position pos Legended[f_{i},label] identify the function in a legend PopupWindow[f_{i},cont] attach a popup window to the function StatusArea[f_{i},label] display in the status area on mouseover Style[f_{i},styles] show the function using the specified styles Tooltip[f_{i},label] attach a tooltip to the function Tooltip[f_{i}] use functions as tooltips  Wrappers w can be applied at multiple levels:

w[f_{i}] wrap the f_{i} w[{f_{1},…}] wrap a collection of f_{i} w_{1}[w_{2}[…]] use nested wrappers  Callout, Labeled, and Placed can use the following positions pos:

Automatic automatically placed labels Above, Below, Before, After positions around the curve x near the curve at a position x Scaled[s] scaled position s along the curve {s,Above},{s,Below},… relative position at position s along the curve {pos,epos} epos in label placed at relative position pos of the curve  Plot has the same options as Graphics, with the following additions and changes:

Automatic use a dotted line for the clipped portion None omit the clipped portion of the curve style use style for the clipped portion  With the default settings Exclusions>Automatic and ExclusionsStyle>None, Plot breaks curves at discontinuities and singularities it detects. Exclusions>None joins across discontinuities and singularities.
 Exclusions>{x_{1},x_{2},…} is equivalent to Exclusions>{x==x_{1},x==x_{2},…}.
 PlotLegends>"Expressions" uses the f_{i} as the legend text.
 Plot initially evaluates f at a number of equally spaced sample points specified by PlotPoints. Then it uses an adaptive algorithm to choose additional sample points, subdividing a given interval at most MaxRecursion times.
 Since only a finite number of sample points are used, it is possible for Plot to miss features of f. Increasing the settings for PlotPoints and MaxRecursion will often catch such features.
 Themes that affect curves include:

"ThinLines" thin plot lines "MediumLines" medium plot lines "ThickLines" thick plot lines  The arguments supplied to functions in MeshFunctions and RegionFunction are x, y. Functions in ColorFunction are by default supplied with scaled versions of these arguments.
 ScalingFunctions>"scale" scales the coordinate; ScalingFunctions{"scalex","scaley"} scales both the and coordinates.
