LineTo

Then use the lineTo API to draw a line from the start point to the end point passed in to the lineTo call .

然后使用lineToAPI来从这个起始点到传递到这个lineTo调用中的端点之间绘制一条直线。

You can also use the lineTo ( x , y ) method to add a subpath to the current path , and position the pen at the specified position .

还可以使用lineTo（x，y）方法添加一个子路径到当前路径，并将画笔定位在一个指定的位置。

There is also a similar quadraticCurveTo ( cpx , cpy , x , y ) method that takes a coordinate and a curve control point coordinate , but otherwise behaves similarly to lineTo () .

还有一个类似的quadraticCurveTo（cpx，cpy，x，y）方法，该方法以一个坐标和一个曲线控制点坐标为参数，但是其行为类似于lineTo（）。

After drawing both axes , you draw the gridlines along with their labels by evenly spacing them and then drawing the lines using the same combination of moveTo , lineTo , and stroke .

绘制水平和垂直轴线后，沿着它们的标签绘制网格线，方法是均匀间隔它们，然后使用相同的moveTo、lineTo和stroke组合来绘制这些直线。
