PowerPoint's chart feature enables you to convert complex tables of numbers into easily viewed charts and graphs. You can control many visual elements in your chart or graph, including whether to display the numbers representing the scales along the horizontal and vertical axes. If you deleted the scales for any reason, you can easily make them visible again using PowerPoint's chart tools. You can also add labels to the scales to denote the units of measurement in your chart.
