bqplot.interacts.TwoDSelector

class bqplot.interacts.TwoDSelector(**kwargs)[source]

Two-dimensional selector interaction.

Base class for all selectors which select data in both the x and y dimensions. The attributes ‘x_scale’ and ‘y_scale’ should be provided.

x_scale

An instance of Scale – This is the scale which is used for inversion from the pixels to data co-ordinates in the x-direction. This scale is used for setting the selected attribute for the selector along with y_scale.

y_scale

An instance of Scale – This is the scale which is used for inversion from the pixels to data co-ordinates in the y-direction. This scale is used for setting the selected attribute for the selector along with x_scale.
