Excel - IF function

Image
If function is a logic function. It does two things: Whether the criteria is met Return a value based on whether the criteria is met or not. If the criteria is met, it returns one value; if the criteria is not met, it returns a different value. The reason IF function is confusing for some Excel users is that it does two things: a logical test, AND a return value depending on the logical test result, while the name of "IF" implies it only does a logical test.

Excel - Hierarchical chart (Treemap)

Image
If you have hierarchical data, you can create beautiful hierarchical charts. For example, in a university, there are students of different majors in departments, and departments in schools. Suppose we have data below, showing number of students in each school, department and major. In this example, we show you how to make treemap chart. The other type of hierarchical chart is sunburst chart. The data is equivalent if all the cells are filled. I like the following format better. 1. Select the data, then click Insert > Charts > Other Charts > Hierarchical . Select Treemap .  2. A nice-looking treemap chart is shown. The blue area shows all engineering students. The orange area shows all business students. Size of each rectangle is proportional to the number of students in each major.
