Please try double-clicking (left button) and see if it allows you to reset the axis on your scatter plot. Please check that first
You can try right clicking again and then choose Edit Axis.
If that doesn't work, try to ZOOM by dragging and dropping a rectangle around the circles you wish to emphasize.
As a last resort: Are you accessing this through Tableau Server, Online, or Public? If so, it's possible you don't have admin rights to modify the axes. Let us know if any of these work for you.
Thanks Michael - I'm still getting nowhere fast. I've emailed the site admin and waiting to hear back
I'm guessing-- since this is online-- you don't have rights to modify the axes.
They should be able to change this (or at least allow for a ZOOM function). Good luck to you!
