EnhancedPlot

Plot with several enhancements added for singularities, asymptotes, surd values and non-interval domains

Contributed by: Dennis M Schneider

ResourceFunction["EnhancedPlot"][f,{x,x_min,x_max}]

returns a plot with several enhancements given by options.

Details and Options

The most significant options are "Asymptote", "Exception", "FindExceptions", "FindAsymptotes", "PowerBehavior" and "ZeroToNull".

Vertical asymptotes can be plotted by setting the "Asymptote" option to a list of x coordinates at which there are infinite (possibly one-sided) discontinuities.

Point discontinuities can be plotted by setting the "Exception" option to a list of x coordinates where possible exceptions occur. Removable discontinuities are denoted by an empty circle. Jump discontinuities are denoted by one or more empty circles at the points of discontinuity (the "jump points"). Infinite discontinuities are drawn as vertical asymptotes. A filled circle is drawn at all other points.

Set "FindExceptions" to True to use ResourceFunction["FunctionDiscontinuities"] to find the discontinuities.

Set "FindAsymptotes" to True to use ResourceFunction["Asymptotes"] to find the various types of asymptotes: "Horizontal", "Vertical", "Oblique", "Parabolic" or "Other".

Set "PowerBehavior" to Real (the default) to insure that odd roots of negative real numbers are returned as negative real numbers instead of the imaginary numbers. Set "PowerBehavior" to Complex to restore the Wolfram Language’s default behavior.

Set "ZeroToNull" to True (the default) to change the Wolfram Language’s default behavior of assigning the value 0 when none of the conditions given in the piecewise function apply to assigning the value Null. Set "ZeroToNull" to False to restore default behavior.

"PointStyle" will not accept color directives.

ResourceFunction["EnhancedPlot"] accepts the following options for adding enhancements:

"Asymptote"

{}

list of points where the function has vertical asymptotes

"AsymptoteStyle"

graphics directive to specify the style for each asymptote

"DrawPoint"

{}

list of points to add to the plot

"DrawPointStyle"

AbsolutePointSize[7]

graphics directives to specify style(s) for the points given with "DrawPoint"

"Exception"

{}

list of points where the function has discontinuities

"FindExceptions"

Automatic

whether to use ResourceFunction["FunctionDiscontinuities"] to find the discontinuities

"HorizontalAsymptote"

{}

list of points where horizontal asymptotes should be drawn

"HorizontalAsymptoteStyle"

graphics directive to specify the style for each horizontal asymptote

"PointStyle"

AbsolutePointSize[7]

graphics directive to specify the style for the point(s) where the function has a discontinuity; color directives are not allowed

"PowerBehavior"

Real

odd roots of negative real numbers are returned as negative real numbers

"ZeroToNull"

True

whether to change the default value of a piecewise function from zero to Null

In addition to these options, ResourceFunction["EnhancedPlot"] accepts any of the options for Plot, as well as the option "ExcludeRemovableDiscontinuities" for the resource function FunctionDiscontinuities.

PowerBehavior (1)

By default, the Wolfram Language returns the principal root of a number. If the number is real and negative and the root is odd, then the principal root is an imaginary number. Setting "PowerBehavior" to Real (the default) will force EnhancedPlot to plot the positive root:

Out[53]=

ZeroToNull (5)

By default, the Wolfram Language does not produce a correct plot of a piecewise function whose domain consists of disjoint intervals. The reason is that it uses 0 as the default value if none of the conditions apply:

$Clear[f] f[x_] := \!\(\* TagBox[GridBox[{ {"\[Piecewise]", GridBox[{ { FractionBox["1", RowBox[{"1", "+", SuperscriptBox["x", "4"]}]], RowBox[{"x", "<", "1"}]}, { FractionBox["1", SuperscriptBox[ RowBox[{"(", RowBox[{"1", "-", "x"}], ")"}], "2"]], RowBox[{"x", ">", "3"}]} }, AllowedDimensions->{2, Automatic}, Editable->True, GridBoxAlignment->{"Columns" -> {{Left}}, "ColumnsIndexed" -> {}, "Rows" -> {{Baseline}}, "RowsIndexed" -> {}}, GridBoxItemSize->{"Columns" -> {{Automatic}}, "ColumnsIndexed" -> {}, "Rows" -> {{1.}}, "RowsIndexed" -> {}}, GridBoxSpacings->{"Columns" -> { Offset[0.27999999999999997`], { Offset[0.84]}, Offset[0.27999999999999997`]}, "ColumnsIndexed" -> {}, "Rows" -> { Offset[0.2], { Offset[0.4]}, Offset[0.2]}, "RowsIndexed" -> {}}, Selectable->True]} }, GridBoxAlignment->{"Columns" -> {{Left}}, "ColumnsIndexed" -> {}, "Rows" -> {{Baseline}}, "RowsIndexed" -> {}}, GridBoxItemSize->{"Columns" -> {{Automatic}}, "ColumnsIndexed" -> {}, "Rows" -> {{1.}}, "RowsIndexed" -> {}}, GridBoxSpacings->{"Columns" -> { Offset[0.27999999999999997`], { Offset[0.35]}, Offset[0.27999999999999997`]}, "ColumnsIndexed" -> {}, "Rows" -> { Offset[0.2], { Offset[0.4]}, Offset[0.2]}, "RowsIndexed" -> {}}], "Piecewise", DeleteWithContents->True, Editable->False, SelectWithContents->True, Selectable->False, StripWrapperBoxes->True]\) Plot[f[x], {x, -5, 5}, PlotStyle -> Purple]$

Out[55]=

A correct plot is obtained by manually setting the default value of the Piecewise to Null:

In[56]:=

$Clear[f] f[x_] := \!\(\* TagBox[GridBox[{ {"\[Piecewise]", GridBox[{ { FractionBox["1", RowBox[{"1", "+", SuperscriptBox["x", "4"]}]], RowBox[{"x", "<", "1"}]}, { FractionBox["1", SuperscriptBox[ RowBox[{"(", RowBox[{"1", "-", "x"}], ")"}], "2"]], RowBox[{"x", ">", "3"}]}, {"Null", "True"} }, AllowedDimensions->{2, Automatic}, Editable->True, GridBoxAlignment->{"Columns" -> {{Left}}, "ColumnsIndexed" -> {}, "Rows" -> {{Baseline}}, "RowsIndexed" -> {}}, GridBoxItemSize->{"Columns" -> {{Automatic}}, "ColumnsIndexed" -> {}, "Rows" -> {{1.}}, "RowsIndexed" -> {}}, GridBoxSpacings->{"Columns" -> { Offset[0.27999999999999997`], { Offset[0.84]}, Offset[0.27999999999999997`]}, "ColumnsIndexed" -> {}, "Rows" -> { Offset[0.2], { Offset[0.4]}, Offset[0.2]}, "RowsIndexed" -> {}}, Selectable->True]} }, GridBoxAlignment->{"Columns" -> {{Left}}, "ColumnsIndexed" -> {}, "Rows" -> {{Baseline}}, "RowsIndexed" -> {}}, GridBoxItemSize->{"Columns" -> {{Automatic}}, "ColumnsIndexed" -> {}, "Rows" -> {{1.}}, "RowsIndexed" -> {}}, GridBoxSpacings->{"Columns" -> { Offset[0.27999999999999997`], { Offset[0.35]}, Offset[0.27999999999999997`]}, "ColumnsIndexed" -> {}, "Rows" -> { Offset[0.2], { Offset[0.4]}, Offset[0.2]}, "RowsIndexed" -> {}}], "Piecewise", DeleteWithContents->True, Editable->False, SelectWithContents->True, Selectable->False, StripWrapperBoxes->True]\) Plot[f[x], {x, -5, 5}, PlotStyle -> Purple]$

EnhancedPlot automatically sets the default value of Piecewise to Null:

Return default Plot behavior by setting the option "ZeroToNull" to False:

Note that with the option "ZeroToNull" set to False, "FindExceptions" will list the break points as jump discontinuities:

Possible Issues (4)

The resource function Asymptotes can be very slow:

In[63]:=

$Clear[f] f[x_] := \!\(\* TagBox[GridBox[{ {"\[Piecewise]", GridBox[{ { RowBox[{ FractionBox["1", RowBox[{"1", "+", SuperscriptBox["x", "2"]}]], "+", "x"}], RowBox[{"x", "<", RowBox[{"-", "1"}]}]}, { RowBox[{ SuperscriptBox["x", RowBox[{"5", "/", "3"}]], "-", "1"}], RowBox[{ RowBox[{"-", "1"}], "<=", "x", "<", "2"}]}, { RowBox[{"1", "/", "x"}], RowBox[{"2", "<", "x", "<", "3"}]}, { RowBox[{"Cos", "[", "x", "]"}], RowBox[{"3", "<", "x", "<", "4"}]} }, AllowedDimensions->{2, Automatic}, Editable->True, GridBoxAlignment->{"Columns" -> {{Left}}, "Rows" -> {{Baseline}}}, GridBoxItemSize->{"Columns" -> {{Automatic}}, "Rows" -> {{1.}}}, GridBoxSpacings->{"Columns" -> { Offset[0.27999999999999997`], { Offset[0.84]}, Offset[0.27999999999999997`]}, "Rows" -> { Offset[0.2], { Offset[0.4]}, Offset[0.2]}}, Selectable->True]} }, GridBoxAlignment->{"Columns" -> {{Left}}, "Rows" -> {{Baseline}}}, GridBoxItemSize->{"Columns" -> {{Automatic}}, "Rows" -> {{1.}}}, GridBoxSpacings->{"Columns" -> { Offset[0.27999999999999997`], { Offset[0.35]}, Offset[0.27999999999999997`]}, "Rows" -> { Offset[0.2], { Offset[0.4]}, Offset[0.2]}}], "Piecewise", DeleteWithContents->True, Editable->False, SelectWithContents->True, Selectable->False, StripWrapperBoxes->True]\) ResourceFunction["Asymptotes"][f[x], x, y]$

Out[64]=

This contributes a significant amount of time to EnhancedPlot if the setting "FindAsymptotes"→True is used:

In[65]:=

$Clear[f] f[x_] := \!\(\* TagBox[GridBox[{ {"\[Piecewise]", GridBox[{ { RowBox[{ FractionBox["1", RowBox[{"1", "+", SuperscriptBox["x", "2"]}]], "+", "x"}], RowBox[{"x", "<", "0"}]}, { RowBox[{ SuperscriptBox["x", RowBox[{"5", "/", "3"}]], "-", "1"}], RowBox[{"0", "<=", "x", "<", "2"}]}, { RowBox[{"1", "/", "x"}], RowBox[{"2", "<", "x", "<", "3"}]}, { RowBox[{"Cos", "[", "x", "]"}], RowBox[{"3", "<", "x", "<", "4"}]} }, AllowedDimensions->{2, Automatic}, Editable->True, GridBoxAlignment->{"Columns" -> {{Left}}, "Rows" -> {{Baseline}}}, GridBoxItemSize->{"Columns" -> {{Automatic}}, "Rows" -> {{1.}}}, GridBoxSpacings->{"Columns" -> { Offset[0.27999999999999997`], { Offset[0.84]}, Offset[0.27999999999999997`]}, "Rows" -> { Offset[0.2], { Offset[0.4]}, Offset[0.2]}}, Selectable->True]} }, GridBoxAlignment->{"Columns" -> {{Left}}, "Rows" -> {{Baseline}}}, GridBoxItemSize->{"Columns" -> {{Automatic}}, "Rows" -> {{1.}}}, GridBoxSpacings->{"Columns" -> { Offset[0.27999999999999997`], { Offset[0.35]}, Offset[0.27999999999999997`]}, "Rows" -> { Offset[0.2], { Offset[0.4]}, Offset[0.2]}}], "Piecewise", DeleteWithContents->True, Editable->False, SelectWithContents->True, Selectable->False, StripWrapperBoxes->True]\) ResourceFunction["EnhancedPlot"][f[x], {x, -4, 4}, "FindExceptions" -> True, "FindAsymptotes" -> True]$

Out[66]=

On the other hand, "FindExceptions" is very fast:

In[67]:=

$Clear[f] f[x_] := \!\(\* TagBox[GridBox[{ {"\[Piecewise]", GridBox[{ { RowBox[{ FractionBox["1", RowBox[{"1", "+", SuperscriptBox["x", "2"]}]], "+", "x"}], RowBox[{"x", "<", "0"}]}, { RowBox[{ SuperscriptBox["x", RowBox[{"5", "/", "3"}]], "-", "1"}], RowBox[{"0", "<=", "x", "<", "2"}]}, { RowBox[{"1", "/", "x"}], RowBox[{"2", "<", "x", "<", "3"}]}, { RowBox[{"Cos", "[", "x", "]"}], RowBox[{"3", "<", "x", "<", "4"}]} }, AllowedDimensions->{2, Automatic}, Editable->True, GridBoxAlignment->{"Columns" -> {{Left}}, "Rows" -> {{Baseline}}}, GridBoxItemSize->{"Columns" -> {{Automatic}}, "Rows" -> {{1.}}}, GridBoxSpacings->{"Columns" -> { Offset[0.27999999999999997`], { Offset[0.84]}, Offset[0.27999999999999997`]}, "Rows" -> { Offset[0.2], { Offset[0.4]}, Offset[0.2]}}, Selectable->True]} }, GridBoxAlignment->{"Columns" -> {{Left}}, "Rows" -> {{Baseline}}}, GridBoxItemSize->{"Columns" -> {{Automatic}}, "Rows" -> {{1.}}}, GridBoxSpacings->{"Columns" -> { Offset[0.27999999999999997`], { Offset[0.35]}, Offset[0.27999999999999997`]}, "Rows" -> { Offset[0.2], { Offset[0.4]}, Offset[0.2]}}], "Piecewise", DeleteWithContents->True, Editable->False, SelectWithContents->True, Selectable->False, StripWrapperBoxes->True]\) ResourceFunction["EnhancedPlot"][f[x], {x, -4, 4}, "FindExceptions" -> True]$

Out[68]=

The resource function Asymptotes can miss the asymptotes of some functions:

In[69]:=

$Clear[f] f[x_] := \!\(\* TagBox[GridBox[{ {"\[Piecewise]", GridBox[{ { FractionBox["1", RowBox[{"1", "+", RowBox[{"x", " ", SuperscriptBox[ RadicalBox["x", "3", MultilineFunction->None, SurdForm->True], "2"]}]}]], RowBox[{"x", "<", RowBox[{"-", "1"}]}]}, { RowBox[{"Sin", "[", RowBox[{"4", " ", "x"}], "]"}], RowBox[{ RowBox[{"-", "1"}], "<=", "x", "<", "0"}]}, {"0", RowBox[{"x", "==", "0"}]}, { RowBox[{"Sin", "[", RowBox[{"4", " ", "x"}], "]"}], RowBox[{"0", "<", "x", "<", FractionBox["1", "2"]}]}, {"2", RowBox[{ FractionBox["1", "2"], "<=", "x", "<", "1"}]}, { FractionBox["\[Pi]", "2"], RowBox[{"x", "==", "1"}]}, { FractionBox["1", RowBox[{"1", "-", "x"}]], RowBox[{"x", ">", "1"}]} }, AllowedDimensions->{2, Automatic}, Editable->True, GridBoxAlignment->{"Columns" -> {{Left}}, "Rows" -> {{Baseline}}}, GridBoxItemSize->{"Columns" -> {{Automatic}}, "Rows" -> {{1.}}}, GridBoxSpacings->{"Columns" -> { Offset[0.27999999999999997`], { Offset[0.84]}, Offset[0.27999999999999997`]}, "Rows" -> { Offset[0.2], { Offset[0.4]}, Offset[0.2]}}, Selectable->True]} }, GridBoxAlignment->{"Columns" -> {{Left}}, "Rows" -> {{Baseline}}}, GridBoxItemSize->{"Columns" -> {{Automatic}}, "Rows" -> {{1.}}}, GridBoxSpacings->{"Columns" -> { Offset[0.27999999999999997`], { Offset[0.35]}, Offset[0.27999999999999997`]}, "Rows" -> { Offset[0.2], { Offset[0.4]}, Offset[0.2]}}], "Piecewise", DeleteWithContents->True, Editable->False, SelectWithContents->True, Selectable->False, StripWrapperBoxes->True]\) ResourceFunction["Asymptotes"][f[x], x, y]$

Out[70]=

The resource function FunctionDiscontinuities will find the exceptions:

In[71]:=

Out[72]=

EnhancedPlot sometimes misses a removable discontinuity:

In[73]:=

Out[73]=

However, the discontinuity can be listed manually:

In[74]:=

Out[74]=

When a discontinuity denoted by a filled circle is overlapped by a empty circle, the filled circle is covered by the empty circle. That is, the empty circle is not really empty (see behavior at x=4):
