BubblesDataSet¶

class visualife.core.BubblesDataSet(converter, *args, **kwargs)¶

Creates a BarDataSet object with X, Y and Z data (if given)

Bubble chart displays three dimensions of data. Radius of each bubble is proportional to the square root of Z value of each point

Parameters:

converter (DataConverter) – referance to converter for calculating screen coordinates for this DataSet
*args – data to be plotted; see DataSet.__init__() documentation

Keyword Arguments (**kwargs)(**kwargs):

markersize (float) – a value used to scale radius of each bubbles
colors (list [ string ], list [ float ] or list [ color in HEX format ]) – define fill color for points; the colors are cycled over for all points, so if the list contains a single elements, all points will have the same fill color
stroke (float or color in HEX format ) - stroke color
stroke_width (float) - stroke width
title (string) - title of this data series; if not provided, the word “bubble chart” will be used
converter_type (string) - converter type to calculate axis range - may be “primary” (bottom and left axis) or “secondary” (upper and rigth axis)
