Purpose

Interactive data viewer.

Synopsis

fig = plotgui(data)
fig = plotgui(data,'PropertyName',PropertyValue,...)
fig = plotgui('update','PropertyName',PropertyValue,...)

Description

Plots input data data and provides a control toolbar in the Plot Controls window to select portions of the data to view. The toolbar allows interactive selection, exclusion, and classing of rows or columns of data. The PLOTGUI command has various display options that are given as 'PropertyName', 'PropertyValue' pairs or as a single keyword. Properties and Keywords are discussed below.

Inputs

  • data = input data, can be class "double" or "dataset". The description given below is generally listed for two-way data arrays.
Notes: Options specific to data that are three-way or image are noted explicitly. PLOTGUI uses the dataset labels, classes, etc. when data is class "dataset".
  • 'update' is used as a keyword input to modify options for an existing PLOTGUI figure without providing new data

Outputs

  • fig = the handle of the figure in which the data is displayed

Plot Controls

The toolbar consists of

  • 1) a menu bar with File, Edit, View, and Plot menus (see Plot Controls Window Menus )
  • 2) a figure selection dropdown menu,
  • 3) three axis menus (labeled x, y, and z),
  • 4) plot update controls Plot button and auto-update checkbox, and Select button.

Each figure in the figure selection dropdown menu menu can be modified by the PLOTGUI controls. Selecting a figure from this menu will bring that figure into view and indicate the selected axis menu settings. A "+" or a "\*" next to a figure's name indicates that it is linked with another figure (see Duplicate Figure below).

The axis menus (labeled x, y, and z) select what parts of the data should be used for the plot. Each column or row selected in the y-axis menu will be plotted against the column, row or index selected in the x-axis menu. If any selection is made on the z-axis menu, then each y-axis selection is also plotted against the column or row selected in the z-axis menu to make a three-dimensional plot.

If the input data is three-way it is assumed to be a multivariate image, and the y-axis is slice or slab and the figure default is imagesc(dat(:,:,1)). This is also true if data is class "dataset" with the type field set to 'image' or 'image'.

If the auto-update checkbox is selected, figures are updated automatically when new axis-menu selections are made. Otherwise, the Plot button must be pressed before any changes are reflected in the figure.

The Select button allows the user to select plotted points in the current figure. After clicking Select, the current figure will be brought to the front and points are selected using the current selection tool (selected using the Tool button; see also Edit/Selection Mode menu). To extend a selection (i.e. add new points to the already selected points), use the shift-key while pressing the mouse button. To remove points from the selection, use the control-key while pressing the mouse button. To keep from making any selection, press "Esc" or "Escape".

Properties and Keywords

The following is a list of available properties. Each should be included as a 'PropertyName', 'PropertyValue' pair in an initial PLOTGUI call or a PLOTGUI 'update' call. Note that calls to PLOTGUI for PropertyName and PropertyValue are case insensitive.

The current value of almost all properties can be retrieved using the GETAPPDATA function on the PLOTGUI figure and requesting the property of interest. Note that calls to GETAPPDATA are case sensitive and PropertyName must be in all lower-case. The I/O format is:

currentvalue = getappdata(fig,'propertyname')

where fig is the handle of the PLOTGUI figure. If 'propertyname' is not included getappdata(fig) will list all the properties and their current values. Properties and their possible values follow:

  • AxisMenuValues: {[x] [y] [z]}, Two or three element cell containing indices or strings indicating which item, or items, to select in each of the three axis pull down menus. In [x] or [y] a value of 0 (zero) means to select index number. In [z] a value of 'none' means to not use the z-axis.
  • AxisMenuDefaults: Axis menu defaults are axis menu values used if the axis menu values can not be restored. The input format is the same as axismenuvalues.
  • Figure: [scalar integer], Figure on which data should be plotted {default is current figure}.
  • New: Key word - no associated PropertyValue. Creates a new figure for display of data. This is equivalent to an initial PLOTGUI call.
  • PlotBy: [scalar integer], Dimension (mode) for the axis menu selections: 0 = special "data browser", 1 = rows, 2 = columns, etc. (see View menu). The default is 2 or the number of modes in the data if larger than 2-way.
  • VSIndex: [ 1 1] {default}, Two element vector indicating if "Index" should be offered on x and y axis menus. A 1 indicates that it should be offered as a selection and a 0 indicates that it should not e.g. [1 1] indicates that it should be offered for both the x-axis and y-axis.

Image Specific Properties

  • Image: Key word - no associated PropertyValue. Unfolds a 2 or 3-way array and displays it as and image, allowing selection, classing, and exclusion of individual pixels.
  • Unfold: Key word - no associated PropertyValue. Pseudonym for "image".
  • AsImage: Key word - no associated PropertyValue. Display 3-way data that have already been unfolded as an image allowing selection, classing, and exclusion of individual pixels.
  • slabcolormode: [‘rgb’] {default}, <String>, determins the colormap used when viewing more than 3 image slabs in a false-color image. Each pixel is assigned a single color from the colormap based on the slab with the largest value for that pixel. This value is then scaled based on the slab color contrast setting. lines = draw from standard line color sequence; rgb = similar to lines but starts with red, green, blue; classes = draw from color scheme used for class symbols; jet = interpolate from the jet color scheme; colormap = interpolate from current figure's colormap.
  • slabcolorcontrast: [0.8] {default}, Set the level of intensity contrast shown for each slab when viewing more than 3 slabs in a false-color image. The higher the value, the more the base color is scaled by the images value. A value of zero shows the color without scaling.
  • viewautocontrast: [0] {default}, A Boolean that turns on/off the use of auto-contrasting on images. When on, image data magnitude is truncated to 3 times the standard deviation. Helps adjust the color scale of images when unusually large or small values are present.
  • viewinterpolated: [0] {default}, A Boolean that turns on/off the use of interpolated-color images. When on, images are interpolated to higher spatial resolution. Note that not all display modes support interpolation. Other settings may disable this feature.
  • viewpixelscale: [0] {default}, Turns on/off the display of pixel axis scales on images. When off, axis scales will be hidden unless user defines an image axisscale. When on, axis scales will be shown in pixels if no user-defined image axisscale is set.
  • imagegunorder: [1 2 3] {default}, <Vector>, determines the order of the color used for false color images. 1 = red, 2 = green, 3 = blue.
  • viewdensity: [1] {default} A Boolean that turns on/off use of density plots for images, turn off to force the use of a scatter plot.
  • densitybinsmin: [64] {default}, Minimum number of bins to use in image density plots.

Plot Properties

  • LineStyle: <string>, Defines line style (see PLOT).
  • PlotType: <string>, String used to select plot type {default [ ] is atuomatic selection}. Other values are 'scatter', 'bar', 'none' ('none' = do no plotting). Automatic plotting checks to see if data is continuous (line plot), has steps (monotonic), otherwise (scatter).

  • classcolormode: [‘’] {default}, <String> Specifies a standard colormap to use for class colors. Empty (the default) uses a standard "optimized" color map (recommended). "figure" uses the colormap set on the current figure. Any other setting is assumed to be a standard colormap name. If using "figure" you must update the plot (by clicking the "plot" button or issuing an 'update' command) after changing the figure colormap to have the change take effect.
  • connectclassmethod: [‘pca’] {default}, <String> Specifies method used to outline classes (when connectclasses is (1)).
    • pca uses PCA confidence ellipses
    • outline draws a border around the outermost class members,

  • autosizemarkers: [0] {default}, A Boolean that turns on/off the auto adjusting the size of symbols. When (1), and no symbol size is specified, symbol size is adjusted to axes size and smaller symbols are used when axis is small.

On-Event Properties

  • CloseGUICallback: Command(s) to execute when the figure is closed.
  • InfoReqCallback: Command executed when information on a selected point is requested.
  • PlotCommand: Command executed after plotting (e.g. draw limits, assign ButtonDownFcns, modifiy axes, ...).

Confidence Limit Properties

  • ConfLimits: Boolean flag to make "Conf. Limits" controls visible. 1 = show controls (PLOTGUI does nothing with these controls, thus the routine specified in '[plotcommand-]' must be set to use values).
  • LimitsValue: Value for Conf. Limits editbox.
  • ShowLimits: Value for "Conf. Limits" checkbox (1 = checked).

Color Properties

  • colorby: [] {default}, Specifies an item number (from the data’s ‘plotby’ mode), or an explicit vector of values to use in coloring the data. When not empty, the given values or index into the dataset is used to color-code the plotted data using the class color scale.
  • colorbybins: [30] {default}, Specifies the number of color bins to group the ‘colorby’ vector into. The more bins, the slower the plotting and more complex the legend, but the more detailed the color mapping. Default is recommended.
  • colorbyscale: [‘linear’] {default} <String>, specifies the type of ‘colorby’ bin mapping to use. "linear" maps colorby values to color maintaining the scale of the values. "nonlinear" maps values to color compressing values into sorted non-linear bins (may increase color contrast).

Plot Controls Properties

  • validplotby: [] {default}, specifies the mode(s) the user is permitted to select from the "Plot" menu. Empty [] allows any mode in the data.
  • axismenuenable: [1 1 1] {default} <Vector>, enabling/disabling the [X Y Z] axis menus. If off (0), the specified axis menu is not enabled and the user cannot change the default selected value. See AxisMenuValues property to set the default value.
  • axisautoinvert: [1] {default}, When on (1) x-axis will be inverted in direction if the axisscale in the data is in decreasing order. When -1, x-axis will ALWAYS be inverted (irrespective of the data direction). When 0, axis will never invert.
  • labelwithnumber: [‘auto’] {default}, <String> Can be set to ‘on’, ’off’, or ‘auto’. Controls numbering of axis menu items (appended within parenthesis at the end of the label), auto adds numbering if there are duplicate.
  • autoduplicate: [1] {default}, A Boolean. When on (1) a clicked sub-plot is automatically duplicated as a single axis in a new figure.
  • autopopulate: [1] {default}, A Boolean, when on (1) new sub-plots are automatically populated with results. When off (0) subplots are left empty for the user to populate manually.
  • maximumyitems: [200000] {default}, specifies the maximum number of items allowed to be shown in the y-axis listbox menu.
  • maximumitems: [500] {default}, specifies the maximum number of items allowed to be shown in the x- and z-axis pull-down menus.
  • maximumdatasummary: [1000] {default}, specifies the maximum number of items allowed to be shown in the "data" view of the "Data Summary" plot mode.
  • maxclassview: [200] {default}, specifies the maximum number of classes to display in a scatter plot.

Figure Linking Properties

WARNING! Modifying these settings can lead to unexpected results!

  • ControlBy: Reassign control for PLOTGUI figure.
  • TimeStamp: Time-stamp of last time this figure was updated (can be set to any string to isolate figure from updating by parents).

Other Miscellaneous Properties

  • UIControl: Add extra uicontrol(s) to PLOTGUI control toolbar for use with current figure (buttons, sliders, etc.). The value passed to UIControl should be a cell in which each entry is the tag of a new object to create and the value of that field should contain a cell of uicontrol property / value pairs to set for that object. For example:
    myobj.mybtn = {'style', 'pushbutton', 'string', 'new fig', 'callback', 'figure'};
    plotgui('update','uicontrol',myobj)
    creates a button with the tag 'mybtn' on the controls for the current figure.
    • In addition to standard object properties, the special property 'updatecallback' can be set on an object. This callback will be executed whenever the Plot Controls window is updated. The variables targfig and h will be available to the callback to indicate the current "target figure" handle and the current object's handle, respectively. This property is useful for updating an object's enable or value properties when multiple figures share the same object (e.g. a checkbox which reflects some user-defined appdata). For an example of its use, see the plotscores function which uses this property for the "Show Error Bars" checkbox.
    • If the cell for any object does not contain a 'position' property for the object, PLOTGUI will manage the object's position.

Read-Only Properties

These properties can only be viewed and are only accessible through the MATLAB getappdata command.

  • Selection: Cell array of currently selected values. Usually the same format as "includ" field of DataSet object where each cell represents the index of selected items in each dimension {rows, columns, slabs, ...}.
  • When selecting elements in greater than 2-dimensional data (and without the use of the 'image' keyword), two cells of this field will be pairs of selected indices: {x,y,[]} or {[],y,z}.
  • FigureType: 'PlotGUI'
  • DataSet: DataSet used in figure (or pointer to figure with actual dataset)
Note: This is set by calling PLOTGUI with a new dataset as an input. The actual DataSet can be retrieved using the getdataset command (see below).

Other Valid Figure Properties

See the MATLAB documentation on FIGURE properties for additional information.

  • HandleVisibility, MenuBar, Name, NumberTitle, Position, Resize, Tag, ToolBar, Units, UserData, Visible, WindowStyle

Examples

The following give some typical use examples:

fig = plotgui(mydata)

plots mydata allowing user to select which column(s) of mydata to plot using pull-down menus. Figure number of plot is returned.

plotgui(mydata,'plotby',1) or plotgui(mydata,'plotby','rows')

plots mydata as in first example except that rows of mydata (dimension 1) are used for pull-down menus instead of columns. Note: When a PLOTGUI property is set for a given figure, the new value will be retained until a new value for that property is provided, even if new data is plotted on the same PLOTGUI figure.

fig = plotgui(mydata,'plotby',1,'axismenuvalues',{[1] [2 3]})

plots rows of mydata; sets controls with row 1 selected for the x-axis and rows 2 and 3 selected for the y-axis. Use:

getappdata(fig,'axismenuvalues')

retrieves current axis menu settings. [axispulldown-]

plotgui(mydata,'viewclasses',1)

plots mydata using symbols to identify the classes stored in dataset mydata. Use a value of 0 (zero) to turn off viewclasses.

plotgui('update','viewclasses',1)

Turns on viewclasses property for current figure without having to pass data to plot (substitute string 'update' for data)

mydata = plotgui('getdataset',fig)

Retrieves mydata from figure fig.

plotgui(myimage,'image')

plots 3-way image myimage selecting slabs of the image for display. The keyword 'image' allows selection, classing and exclusion of pixels in the image.
