A Pharo inspector extension to operate and view DataFrame multiple information in a same inspector view. Currently it displays:

• General informations about the dataframe
• Histograms about all numerical columns of the dataframe
• A scatter matrix of the DataFrame

A configurable limit is set by default to quickly visualize a DataFrame when we are in the inspector. To change the limit, for example to 50000, you can evaluate:

AISpDataFrameInspector maxRows: 50000

EpMonitor disableDuring: [ 
    Metacello new
        baseline: 'AIDataFrameInspector';
        repository: 'github://pharo-ai/data-inspector/src';
	onConflictUseIncoming;
        load ]

spec 
   baseline: 'AIDataFrameInspector' 
   with: [ spec repository: 'github://pharo-ai/data-inspector/src' ].

Just inspect any DataFrame and select the palette with "Data Inspector":

EpMonitor disableDuring: [ 
	Metacello new
		baseline: 'AIDatasets';
		repository: 'github://pharo-ai/datasets';
		load ].

AIDatasets loadIris inspect.

It is also possible to visualize the historigrams of a DataFrame or a DataSeries like this

iris := AIDatasets loadIris.

iris histograms.
(iris column: #'petal length (cm)') histogram.

You can specify the number of intervals to display like this:

iris histogramsBins: 50.
(iris column: #'petal length (cm)') histogramBins: 50.

The scatter matrix can be opened like this:
