Bases: sage.plot.primitive.GraphicPrimitive
Graphics primitive that represents a bar chart.
EXAMPLES:
sage: from sage.plot.bar_chart import BarChart
sage: g = BarChart(range(4), [1,3,2,0], {}); g
BarChart defined by a 4 datalist
sage: type(g)
<class 'sage.plot.bar_chart.BarChart'>
Returns a dictionary with the bounding box data.
EXAMPLES:
sage: b = bar_chart([-2.3,5,-6,12])
sage: d = b.get_minmax_data()
sage: d['xmin']
0
sage: d['xmax']
4
A bar chart of (currently) one list of numerical data. Support for more data lists in progress.
EXAMPLES:
A bar_chart with blue bars:
sage: bar_chart([1,2,3,4])
A bar_chart with thinner bars:
sage: bar_chart([x^2 for x in range(1,20)], width=0.2)
A bar_chart with negative values and red bars:
sage: bar_chart([-3,5,-6,11], rgbcolor=(1,0,0))
A bar chart with a legend (it’s possible, not necessarily useful):
sage: bar_chart([-1,1,-1,1], legend_label='wave')
Extra options will get passed on to show(), as long as they are valid:
sage: bar_chart([-2,8,-7,3], rgbcolor=(1,0,0), axes=False)
sage: bar_chart([-2,8,-7,3], rgbcolor=(1,0,0)).show(axes=False) # These are equivalent
