We've already got grid lines in that blue chart, but just the major ones. With the chart selected we're going to Add Chart Element.
So the idea is at different times you might want to change this part of a chart or another part. You can also click and drag here, make it float if you wish. Fill in a different color, something like that, or rearrange the data in a different way. Now, for some people, this is way too deep, but on the other hand there will be times, I think, for almost anybody using Excel charts, you might want to explore some of these. We now see over on the right-hand side, a series of choices here with different icons for more fine tuning detail. If we don't understand this or we're not quite sure what this means, we might choose More Axis Options.
Now that may not be an obvious term for some people, but both axes represented in this blue chart to the right: Primary Horizontal, Primary Vertical. And many, many times you'll want to make changes to the charts to adjust either the axes, as we see here. Because these are the elements that we often work with as we work with Excel charts. Now, these are going to be covered in chapter four of this course, but I do want to alert you to the now. The leftmost button Add Chart Elements has lots of choices. Chart Design is available with lots of choices. Anytime you click a chart contextual tabs appear in the ribbon menu system. We're looking at the file chapter three chart design tab.
