Hi Kate,

Thanks for the post, welcome to the forum, in answer to your question, create your chart as per normal, formatting as necessary, usually you would set a trend line to ascertain how a particular growth pattern is established in a set of data over a period of time. Note; a Trend line can be applied only to a two dimensional chart.
Oh yes, how to do it; select the chart and on the Menu bar choose the Chart option, from the menu choose Add trendline, from the dialog box slect the type of trendline you wish to display, click OK, I hope that helps, if so please click the resolved link, best regards Pete
