Add images to your graph to use as a template for your graph, add text labels, or for a little pop of extra color! To add an image to your graph, start by opening the Add Item menu and choose Image. Clicking and dragging the image into the expression list is also supported in many browsers.
To Move the image, click on the center point and drag the image to where you’d like to place it. Or, you can manually change the coordinate of the center point in the expression list. This will automatically move the image so that its center is at that new coordinate point. To Resize the image, click and drag any one of the outer points surrounding the image and drag outwards to make larger and inwards to make smaller.
