Excel's ability to create automatic subtotals is a handy feature that can save you a great deal of time.
In addition to manual data filtering Excel enables fully automated filtering based on data from the specified range of cells. Before you can use the advanced filtering feature, you must set up a criteria range. A criteria range is a designated range on a worksheet that conforms to certain requirements.
You can easily count the number of unique values of the range using a simple formula.
In order to get unique items in a range you can use the Advanced Filter to extract the unique values from a column of data and paste them to a new location.
If you want to combine more than two different data series with common horizontal and different vertical values, you could not just add another axis to the chart. You need to combine several charts into one chart.
Sometimes you want to show several axes in one chart in order to demonstrate each data series with different formatting and with different axis in one chart.
Sometimes, you may want to view two different parts of a worksheet simultaneously - perhaps to make it easier to reference a distant cell in a formula. Or you may want to examine more than one sheet in the same workbook simultaneously.
Every workbook uses a palette of 56 colors, but you can change palette for the current workbook or even change the default colors for new workbooks.
When you need as much space as possible on screen to view a document, you can collapse (or minimize) the Ribbon and then restore it very simple.
