My performance / history graphs are not showing. What should I do?

Some students find that their performance or history graphs do not display. There are two common causes:

You have ad-blockers that prevent the graphs from loading. Try turning your ad-blockers off.

There is a problem with your browser cache. Try purging the browser cache. In Chrome, select Clear browsing data from the More Tools menu. In Firefox, hold down Ctrl and press F5. In Safari, Select Settings, and under "Privacy settings", select Clear cache / Clear history / Clear all cookie data as appropriate.

You can also try using a different browser (for example, if you commonly use Chrome, try Firefox). This will help you determine if the issue is browser or system related
