thanks for the help, John. I actually did try setting the Line type and tried all the others as well. it always lets me save and go back to the page view, but when I preview, then pass the menu to load the page with the chart on it, that's when it hangs. It's so odd, but the documentation you shared is good and quite extensive. I'm new to it , so that will definitely come in handy!  Have you created many types of charts yet?
