At Hogwarts, there are four houses:
toSentence(HOUSES). The bar chart below shows the
number of house points that each house received today.
How many house points did HOUSES[INDEX] receive?

VALUES[INDEX]
house points
Find the bar for HOUSES[INDEX].
style({ stroke: PINK, fill: null, strokeWidth: 2 });
ellipse([INDEX * 3 + 2, -0.6], [1.5, 0.5]);
There is no bar for HOUSES[INDEX], which
means HOUSES[INDEX] recieved 0
house points.
Compare the height of the bar for
HOUSES[INDEX] to the scale on the left.
style({
stroke: PINK,
strokeWidth: 2,
arrows: "->",
strokeDasharray: "-"
});
line([INDEX * 3 + 1.5, VALUES[INDEX] / 10],
[0, VALUES[INDEX] / 10]);
HOUSES[INDEX] received
VALUES[INDEX] house points.
