What do you prefer pies or chocolate bars?
Last time we were exploring risk factors of having a coronary heart disease with the help of Flexmonster Pivot Table Component. In the process, we had been using a flat table, pivot table, and charts above all. This time, we will talk about using pie charts and bar charts for different purposes.
Selecting a type of chart depends primarily on what sort of data you have, at what stage of your analysis you are, and what message you want to convey. Generally, charts and graphs are used for one of the following purposes:
- to show a composition of the data,
- to investigate a distribution and/or trends,
- to express comparisons and/or relationships,
- to illustrate a process or display a location.
