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
GROUP parameters
VARIABLE x1 x2 x3
COMPONENT 0 1 0 0
series_1 0.25 0.35 0.5 0.75
series_2 0.75 0.85 0.5 0.25


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)
plot bars
[<Figure size 640x480 with 1 Axes>]

Total running time of the script: (0 minutes 0.155 seconds)
