Excel 2010 now comes with sparklines. In the past, we needed third party software in order to work with these little creatures. They are now native to Excel. Here’s a look at the Excel 2010 sparklines:

In the above scenario, we have a line sparkline, but Excel 2010 comes with some others such as “column sparkline” and “win/loss sparkline” shown below for the same dataset:

If we consider the conditional formatting data bars introduced in Excel 2007, this is a great addition to Excel 2010.
Most importantly: it is very easy to use. Under the “Insert” tab, close to the “Charts” group you will find the “Sparklines” group. The shaded area in the picture below shows the sparkline location:

Once the sparkline is inserted, you can quickly change style, type, show/hide low/high points, etc:
