Ray

Use this tool to draw a ray in the chart. To do this, follow these steps:

From the "Lines" button menu, select the "Ray" entry.
In the chart, click where you want the ray to start and release the mouse button.
Then, move the ray in the corresponding direction in the chart and release the mouse button.
The ray is created. Unlike the "Segment" drawing element, the ray is limited only on one side. You can now select and move it in parallel or drag at one of the end points to change the start point or the direction.
