Customize your graph's design. Move your line graph. Resize the graph. Change the graph's title.
Once you create your graph, the Design toolbar will open. You can change your graph's design and appearance by clicking one of the variations in the "Chart Styles" section of the toolbar. If this toolbar doesn't open, click your graph and then click the Design tab in the green ribbon. Click and drag the white space near the top of the line graph to move it. You can also move specific sections of the line graph (e.g., the title) by clicking and dragging them around within the line graph's window. Click and drag one of the circles on one of the edges or corners of the graph window in or out to shrink or enlarge your graph. Double-click the title of the graph, then select the "Chart Title" text and type in your graph's name. Clicking anywhere off of the graph's name box will save the text. You can do this for your graph's axes' labels as well.
