No worries Mum! That's why we're having this practice week!

An observation from your Result Chart posts above: if you make them less wide (e.g. less than 1100 pixels wide) we won't have to horizontally scroll the screen to see the entire width of it. For web pages, you can make the browser window less than full screen and the chart web page will resize itself so it is not so wide - then you can still take a screenshot of the whole width of it. Like this, perhaps (1035 pixels wide):
