FeatureSpacePlot

FeatureSpacePlot[{example1,example2,…}]
plots features extracted from the examplei as a scatter plot.
Details and Options




- FeatureSpacePlot can be used on many types of data, including numerical, textual, sounds and images, and combinations of these.
- Each examplei can be a single data element, a list of data elements, an association of data elements, or a Dataset object.
- When possible, FeatureSpacePlot uses the examplei as the point marker in the scatter plot.
- The following forms can be used to specify alternative markers:
-
{example1marker1,…} examples and markers in a list of rules {example1,…}{marker1,…} examples and markers grouped together <marker1example1,… > association keys as markers - Wrappers w can be applied at multiple levels:
-
{…,w[examplei],…} wrap the value examplei w[{example1,example2,…}] wrap all the examples w1[w2[…]] use nested wrappers - The following wrappers w can be used for the examplei:
-
Annotation[examplei,label] provide an annotation for the example Button[examplei,action] define an action to execute when the example is clicked Callout[examplei,label] label the example with a callout Callout[examplei,label,pos] place the callout at relative position pos EventHandler[examplei,…] define a general event handler for the example Hyperlink[examplei,uri] make the example a hyperlink Labeled[examplei,label] label the example Labeled[examplei,label,pos] place the label at relative position pos Legended[examplei,label] identify the example in a legend PopupWindow[examplei,cont] attach a popup window to the example StatusArea[examplei,label] display in the status area on mouseover Style[examplei,styles] show the example using the specified styles Tooltip[examplei,label] attach a tooltip to the example Tooltip[examplei] use example values as tooltips - Callout, Labeled, Placed and LabelingFunction can use the following positions pos:
-
Automatic automatically placed labels Above, Below, Before, After positions around the data Center use the label as the point marker x near the data at a position x {pos,epos} epos in label placed at relative position pos of the data - FeatureSpacePlot has the same options as Graphics, with the following additions and changes:
-
AspectRatio 1 ratio of height to width Axes False whether to draw axes FeatureExtractor Identity how to extract features from which to learn FeatureNames Automatic names to assign to elements of the examplei FeatureTypes Automatic feature types to assume for elements of the examplei Filling None how to fill in stems for each point FillingStyle Automatic style to use for filling LabelingFunction Automatic how to label points LabelingSize Automatic size of callouts and labels MaxPlotPoints Automatic the maximum number of points to include PerformanceGoal $PerformanceGoal aspects of performance to try to optimize PlotLabel None overall label for the plot PlotLabels None labels for data PlotLegends None legends for data PlotMarkers None markers to use to indicate each point PlotRange Automatic range of values to include PlotRangeClipping True whether to clip at the plot range PlotStyle Automatic graphics directives to determine styles of points PlotTheme $PlotTheme overall theme for the plot RandomSeeding 1234 how to seed random numbers - LabelingFunctionpos places the default labels at the position pos.
- LabelingFunction->f specifies that each point should have a label given by f[value,index,lbls], where value is the value associated with the point, index is its position in the data and lbls is the list of relevant labels.
- Possible settings for Method include:
-
Automatic automatically chosen method "LatentSemanticAnalysis" latent semantic analysis method "Linear" automatically choose the best linear method "LowRankMatrixFactorization" use a low-rank matrix factorization algorithm "PrincipalComponentsAnalysis" principal components analysis method "TSNE" t-distributed stochastic neighbor embedding algorithm "UMAP" uniform manifold approximation and projection

AspectRatio (4)
By default, FeatureSpacePlot uses the same width and height:
Specify the height to width ratio:
AspectRatioAutomatic determines the ratio from the plot ranges:
AspectRatioFull adjusts the height and width to tightly fit inside other constructs:

Simple examples such as images and text are shown directly in the plot:
Show the examples as points with the original data in tooltips:
Use Callout to label the points automatically:
