The point is now ready to plot. Instead of just plotting a single dot, this time try marking the spot with an X.
现在可以画点了,但是这一次不是简单地画一个点,而是要用 X 来标记。
This API takes the (x,y) starting point and the text. You do this for each of the data points, creating a bar graph with a label below it for each.
您对每个数据点都执行这个操作,为每个数据点创建一个柱状图,其下带有一个标签。
y So, for each x and y, I plot a point at height given with the value of the a function.
对每个x和,在高度为函数值的地方描点。
So this is giving me now that template, better way of saying it, all right, a template now, for a point is x, y, radius, angle.
其他的方法来进行计算,但是这就是典型的我,要放置它们的地方,因此这就给了我一个模板。
So x is not really the coordinate of the end point.
其实并不是弹簧端点的坐标
It's easy to think of a point as just a list of an x- and a y- coordinate.
或者说有两个元素的数组,把一个点认为是含有x坐标。
