Build a dataset

inputs = linspace(0, 1, 10)[:, None]
outputs_1 = sin(2 * pi * inputs)
outputs_2 = cos(2 * pi * inputs)

dataset = Dataset()
dataset.add_variable("x", inputs, "inputs")
dataset.add_variable("y1", outputs_1, "outputs")
dataset.add_variable("y2", outputs_2, "outputs")

Plot y1 and y2

We can use the Lines plot.

plot = Lines(dataset, variables=["y1", "y2"])
plot.linestyle = ["--", "-"]
plot.execute(save=False, show=True)
