Well, Nick. I sure thought there was a setting for that, but it does appear you're right. So here's your workaround:
Create a second slide that looks like the first, but without your graphic. Click on the first slide and use slide transition (if you like) to move to the next slide. Otherwise, just let it do it on mouse click. Not sure if it's any better than the "hide..." options tho. Why do you think you need to animate the slide onto the graphic to use those options? It doesn't appear that way to me.
