ParallelCoordinatesPlot Properties

Plot title, specified as a character vector, string array, cell array of character vectors, or categorical array. By default, the plot has no title.

To create a multiline title, specify a string array or cell array of character vectors. Each element in the array corresponds to a line of text.

If you specify the title as a categorical array, MATLAB^® uses the values in the array, not the categories.

Example: p = parallelplot(__,'Title','My Title Text')

Example: p.Title = 'My Title Text'

Example: p.Title = {'My','Title'}

Horizontal axis label for describing the set of coordinate variables, specified as a character vector, string array, cell array of character vectors, or categorical array. The CoordinateLabel value appears below the CoordinateTickLabels value in the plot.

To create a multiline label, specify a string array or cell array of character vectors. Each element in the array corresponds to a line of text.

If you specify the label as a categorical array, MATLAB uses the values in the array, not the categories.

Example: p = parallelplot(__,'CoordinateLabel','Measurements')

Example: p.CoordinateLabel = 'Measurements'

Example: p.CoordinateLabel = {'Measurements','(in inches)'}

Coordinate variable labels, specified as a string array, cell array of character vectors, or categorical array. Each coordinate tick label appears directly below the ruler displaying the values for that coordinate variable.

If you specify the labels as a categorical array, MATLAB uses the values in the array, not the categories.

Example: p = parallelplot(__,'CoordinateTickLabels',{'Height','Age','Smoker'})

Example: p.CoordinateTickLabels = {'Height','Age','Smoker'}

Vertical axis label for describing the rows of the data in SourceTable or Data, specified as a character vector, string array, cell array of character vectors, or categorical array.

To create a multiline label, specify a string array or cell array of character vectors. Each element in the array corresponds to a line of text.

If you specify the label as a categorical array, MATLAB uses the values in the array, not the categories.

Example: p = parallelplot(__,'DataLabel','Patients')

Example: p.DataLabel = 'Patients'

Example: p.DataLabel = {'Patients','(data set 1)'}

Legend title, specified as a character vector, string array, cell array of character vectors, or categorical array. Use '' for no title.

To create a multiline title, specify a string array or cell array of character vectors. Each element in the array corresponds to a line of text.

If you specify the title as a categorical array, MATLAB uses the values in the array, not the categories.

Example: p = parallelplot(__,'LegendTitle','My Title Text')

Example: p.LegendTitle = 'My Title Text'

Example: p.LegendTitle = {'My','Title'}

Visibility of legend, specified as 'on' or 'off', or as numeric or logical 1 (true) or 0 (false). A value of 'on' is equivalent to true, and 'off' is equivalent to false. Thus, you can use the value of this property as a logical value. The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState.

Set LegendVisible to 'on' to display the legend or 'off' to hide the legend.

If GroupData is empty ([]), then parallelplot does not display a legend. Otherwise, parallelplot displays a legend by default.

In the legend, parallelplot displays the group names in order of their first appearance in GroupData.

Example: p = parallelplot(__,'LegendVisible','off')

Example: p.LegendVisible = 'off'

Normalization method for coordinates with numeric values, specified as one of the following options.

For more information about these methods, see normalize.

For a coordinate variable that is a logical vector, datetime array, duration array, categorical array, string array, or cell array of character vectors, parallelplot evenly distributes the unique possible values along the coordinate ruler, regardless of the normalization method.

Example: p = parallelplot(__,'DataNormalization','none')

Example: p.DataNormalization = 'zscore'

Data displacement distance along the coordinate rulers, specified as a numeric scalar in the interval [0,1]. The Jitter value determines the maximum distance to displace plot lines from their true value along the coordinate rulers, where the displacement is a uniform random amount. If you set the Jitter property to 1, then adjacent jitter regions just touch. Set the Jitter property to 0 to display the true data values.

Some amount of jitter is particularly helpful for visualizing categorical data because the jittering enables you to distinguish between plot lines more easily. However, the Jitter value affects all coordinate variables, including numeric variables.

Example: p = parallelplot(__,'Jitter',0.5)

Example: p.Jitter = 0.2

Group color, specified in one of these forms:

Choose among these predefined colors, their equivalent RGB triplets, and their hexadecimal color codes.

Here are the RGB triplets and hexadecimal color codes for the default colors MATLAB uses in many types of plots.

By default, parallelplot assigns a maximum of seven unique group colors. When the total number of groups exceeds the number of specified colors, parallelplot cycles through the specified colors.

Example: p = parallelplot(__,'Color',{'blue','black','green'})

Example: p.Color = [0 0 1; 0 0.5 0.5; 0.5 0.5 0.5]

Example: p.Color = {'#EDB120','#77AC30','#7E2F8E'}

Group line style, specified in one of these forms:

Choose among these line style options.

By default, parallelplot assigns a line style of '-' to each group of plot lines. When the total number of groups exceeds the number of specified line styles, parallelplot cycles through the specified line styles.

Example: p = parallelplot(__,'LineStyle',':')

Example: p.LineStyle = {'-.','-','--'}

Group line width, specified as a positive scalar or positive vector in points. By default, parallelplot assigns a line width of 1 to each group of plot lines.

When the total number of groups exceeds the number of specified line widths, parallelplot cycles through the specified line widths.

Example: p = parallelplot(__,'LineWidth',1.5)

Example: p.LineWidth = [0.5 1.5 0.5]

Group line transparency, specified as a numeric scalar or numeric vector with values between 0 and 1. Values closer to 0 specify more transparent lines, and values closer to 1 specify more opaque lines. By default, parallelplot assigns a LineAlpha value of 0.7 to each group of plot lines.

Example: p = parallelplot(__,'LineAlpha',0.75)

Example: p.LineAlpha = [0.2 0.7 0.4]

Group marker symbol for data values along the coordinate rulers, specified in one of these forms:

Choose among these marker options.

By default, parallelplot assigns 'none' as the marker style for each group. When the total number of groups exceeds the number of specified symbols, parallelplot cycles through the specified symbols.

Example: p = parallelplot(__,'MarkerStyle','x')

Example: p.MarkerStyle = {'x','o'}

Group marker size for data values along the coordinate rulers, specified as a nonnegative scalar or nonnegative vector, with values measured in points. By default, parallelplot assigns 6 as the marker size for each group. When the total number of groups exceeds the number of specified values, parallelplot cycles through the specified values.

Example: p = parallelplot(__,'MarkerSize',10)

Example: p.MarkerSize = [4 6 8]

Font name, specified as a system-supported font name. The same font is used for the title, labels, legend title, and group names. The default font depends on the specific operating system and locale.

Example: p = parallelplot(__,'FontName','Cambria')

Example: p.FontName = 'Helvetica'

Font size, specified as a positive scalar. FontSize is the same for the title, labels, legend title, and group names. The default font size depends on the specific operating system and locale.

As you adjust the size of plot elements, the software automatically updates the font size. However, changing the FontSize property disables this automatic resizing.

Example: p = parallelplot(__,'FontSize',12)

Example: p.FontSize = 10

Position property to hold constant when adding, removing, or changing decorations, specified as one of the following values:

Inner size and position of the plot within the parent container (typically a figure, panel, or tab), specified as a four-element numeric vector of the form [left bottom width height]. The inner position does not include the plot title, labels, or legend.

Outer size and position of the full parallel coordinates plot within the parent container (typically a figure, panel, or tab), specified as a four-element numeric vector of the form [left bottom width height]. The default value of [0 0 1 1] includes the whole interior of the container.

Inner size and position of the plot within the parent container (typically a figure, panel, or tab), specified as a four-element numeric vector of the form [left bottom width height]. This property is equivalent to the InnerPosition property.

Position units, specified as one of these values.

When specifying the units as a name-value pair during object creation, you must set the Units property before specifying the properties that you want to use these units for, such as OuterPosition.

Layout options, specified as a TiledChartLayoutOptions or GridLayoutOptions object. This property is useful when the chart is either in a tiled chart layout or a grid layout.

To position the chart within the grid of a tiled chart layout, set the Tile and TileSpan properties on the TiledChartLayoutOptions object. For example, consider a 3-by-3 tiled chart layout. The layout has a grid of tiles in the center, and four tiles along the outer edges. In practice, the grid is invisible and the outer tiles do not take up space until you populate them with axes or charts.

This code places the chart c in the third tile of the grid.

c.Layout.Tile = 3;

To make the chart span multiple tiles, specify the TileSpan property as a two-element vector. For example, this chart spans 2 rows and 3 columns of tiles.

c.Layout.TileSpan = [2 3];

To place the chart in one of the surrounding tiles, specify the Tile property as "north", "south", "east", or "west". For example, setting the value to "east" places the chart in the tile to the right of the grid.

c.Layout.Tile = "east";

To place the chart into a layout within an app, specify this property as a GridLayoutOptions object. For more information about working with grid layouts in apps, see uigridlayout.

If the chart is not a child of either a tiled chart layout or a grid layout (for example, if it is a child of a figure or panel) then this property is empty and has no effect.

Visibility of object, specified as 'on' or 'off', or as numeric or logical 1 (true) or 0 (false). A value of 'on' is equivalent to true, and 'off' is equivalent to false. Thus, you can use the value of this property as a logical value. The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState.

Source table, specified as a table.

You can create a table from workspace variables using the table function, or you can import data as a table using the readtable function.

Table variables to display as coordinates, specified in one of these forms:

If you set the CoordinateVariables property value, then the CoordinateData and CoordinateTickLabels properties update to appropriate values.

Example: p.CoordinateVariables = {'Age','Height','Weight'} specifies the variables named 'Age', 'Height', and 'Weight'.

Table variable for grouping data, specified in one of these forms:

The values associated with your table variable must form a numeric vector, logical vector, categorical array, string array, or cell array of character vectors.

GroupVariable splits the rows in SourceTable into unique groups. parallelplot assigns each group a default color. In the legend, parallelplot displays the group names in order of their first appearance in GroupData.

When you specify GroupVariable, MATLAB updates the GroupData property values.

Example: p.GroupVariable = 'Smoker'

Input data, specified as a numeric matrix.

Variables displayed as coordinates, specified in one of these forms:

Example: p.CoordinateData = [1 5:7]

Values for grouping data, specified as a numeric vector, logical vector, categorical array, string array, or cell array of character vectors.

GroupData splits the rows in SourceTable or Data into unique groups. parallelplot assigns each group a default color. In the legend, parallelplot displays the group names in order of their first appearance in GroupData.

Example: p.GroupData = [1 2 1 3 2 1 3 3 2 3]

Example: p.GroupData = categorical({'blue','red','yellow','blue','yellow','red','red','yellow','blue','red'})

Parent container, specified as a Figure, Panel, Tab, TiledChartLayout, or GridLayout object.

Visibility of the object handle for ScatterHistogramChart in the Children property of the parent, specified as one of these values:

If the object is not listed in the Children property of the parent, then functions that obtain object handles by searching the object hierarchy or querying handle properties cannot return the object. These functions include get, findobj, gca, gcf, gco, newplot, cla, clf, and close.

Hidden object handles are still valid. Set the root ShowHiddenHandles property to 'on' to list all object handles, regardless of their HandleVisibility property setting.
