# Description

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:

```smalltalk

AISpDataFrameInspector maxRows: 50000

```

# Installation

```smalltalk

EpMonitor disableDuring: [ 

    Metacello new

        baseline: 'AIDataFrameInspector';

        repository: 'github://pharo-ai/data-inspector/src';

	onConflictUseIncoming;

        load ]

```

# If you want to depend on it

```smalltalk

spec 

   baseline: 'AIDataFrameInspector' 

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

```

# Usage

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

```smalltalk

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

```st

iris := AIDatasets loadIris.

iris histograms.

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

```

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

```st

iris histogramsBins: 50.

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

```

The scatter matrix can be opened like this:

```st

iris scatterMatrix

```
