The scaling factor is obtained by dividing the height of the graph's axis by the highest value in the data.
比例因子可以用图轴的高度除以数据的最大值来获得。

Concretely, this curl gives you the angular velocity of the rotation, well, with a factor two but that doesn't matter, and the axis of rotation, the direction of the axis of rotation.
它给出了这个旋转的角速率，有一个因子2，但没关系，给出了旋转轴，和旋转轴的方向。

The Y-axis scaling factor is calculated on line 104 in the exact same way as in the bar chart example (see Listing 2).
