dash_pivottable v0.0.2

Dash Pivottable

Dash Pivottable is a Dash component wrapping the react-pivottable library, created by Nicolas Kruchten. It lets you build interactive pivot tables using purely Python.

Getting Started

Install with virtualenv

First, install virtualenv with pip install virtualenv.

Then, make sure to clone this project, create a venv and install requirements:

git clone https://github.com/plotly/dash-pivottable.git
cd dash_pivottable
python3 -m venv ./venv
source venv/bin/activate
pip install -r requirements.txt

And simply run the example in the venv:

python usage.py

References

The following parameters can be modified:

• id (string; optional): The ID used to identify this component in Dash callbacks
• data (list; optional): The input data
• hiddenAttributes (list; optional): contains attribute names to omit from the UI
• hiddenFromAggregators (list; optional): contains attribute names to omit from the aggregator arguments dropdowns
• hiddenFromDragDrop (list; optional): contains attribute names to omit from the drag'n'drop portion of the UI
• menuLimit (number; optional): maximum number of values to list in the double-click menu
• unusedOrientationCutoff (number; optional): If the attributes' names' combined length in characters exceeds this value then the unused attributes area will be shown vertically to the left of the UI instead of horizontally above it. 0 therefore means 'always vertical', and Infinity means 'always horizontal'.

The following props can be used as an input to callbacks, but can't be modified:

• cols (list; optional): Which columns are currently in the column area
• colOrder (string; optional): The order in which column data is provided to the renderer, must be one of "key_a_to_z", "value_a_to_z", "value_z_to_a", ordering by value orders by column total
• rows (list; optional): Which rows is currently inside the row area.
• rowOrder (string; optional): The order in which row data is provided to the renderer, must be one of "key_a_to_z", "value_a_to_z", "value_z_to_a", ordering by value orders by row total
• aggregatorName (string; optional): Which aggregator is currently selected. E.g. Count, Sum, Average, etc.
• vals (list; optional): Attribute names used as arguments to aggregator (gets passed to aggregator generating function)
• rendererName (string; optional): Which renderer is currently selected. E.g. Table, Line Chart, Scatter
• valueFilter (dictionnary; optional): Object whose keys are attribute names and values are objects of attribute value-boolean pairs which denote records to include or exclude from computation and rendering; used to prepopulate the filter menus that appear on double-click

Default Values:

• menuLimit: 500
• unusedOrientationCutoff: 85
• hiddenAttributes: []
• hiddenFromAggregators: []
• hiddenFromDragDrop: []
