This step is a bit complicated, and the general process should be like this:

1, find a vector drawing of the axis, and intercept the vector drawing (that is, the part you need to draw the axis, and intercept it only with the screenshot tool in ppt).

2. Put the drawing axis in the position you want in ppt.

3. Click Animation to set a custom animation, select an action path, and then select a custom path.

4. Set the path you want to choose.

5. If there is no other demand, you can zoom in.
