Example

from hwx import gui
from hwx.gui.XyPlot import XyPlot
from hwx.gui.XyPlot import Curve

plot = XyPlot(title="Plot with Curves")

# the (x, y) points of the curves
x = [1, 2, 4, 5, 6]
y = [1, 3, 4, 1, 7]
curve1 = Curve(plot, x=x, y=y, draggable=False, label="Curve1")
curve1.color = "red"
curve1.linestyle = "dashed"
# another way to define de curve points
y = ([1, 2, 4, 5, 6], [2, 4, 5, 2, 8])
plot.addCurve(x=x, y=y, draggable=False, label="Curve2")
show(plot)
