Adding or changing titles, legend, and grids
On the Chart Elements page, you can give your chart a title and, if desired, a subtitle. Use a title that draws the viewers’ attention to the purpose of the chart: what you want them to see. For example, a better title for this chart might be The Performance of Motor and Other Rental Boats.
It may be of benefit to have labels for the x axis or the y axis. This is where you give people an idea as to the proportion of your data. For example, if we put Thousands in the y axis label of our graph, it changes the scope of the chart entirely. For ease of estimating data you can also display the x or y axis grids by selecting the Display grids options.
You can leave out the legend or include it and place it to the left, right, top or bottom.
