Build a dataset#
Let us consider two series of values for the variables x1, x2 and x3
which we arrange in rows in a Dataset
:
dataset = Dataset()
dataset.add_variable("x1", array([[0.25, 0.35], [0.75, 0.85]]))
dataset.add_variable("x2", array([[0.5], [0.5]]))
dataset.add_variable("x3", array([[0.75], [0.25]]))
dataset.index = ["series_1", "series_2"]
dataset
Plot the two series on a bar chart#
We can use the BarPlot
to display these series,
with one color per series and the values grouped by variable name:
plot = BarPlot(dataset, n_digits=2)
plot.colormap = "PiYG"
plot.execute(save=False, show=True)
