Changing the form of the movable pointer in a graph

Hi—I’m a French teacher very much enjoying the Activity Builder but just dipping my toes into the CL. How do I go about changing the battery on this graph to a musical note?

Line 18 in the graphing calculator contains the battery picture. Make a new line below and and add your musical note picture file as an image:

Set the center the same as the battery and adjust the other parameters as desired. If you’re filling the note, you may need a different shape from the rectangles used to fill.

You can long click on the circle image to change the image. I think that way you keep all the parameters.
