What I Learned in CompSci #30: Charts

Data Representation:
Charts

Used for easier representation of data.

Types of Charts

• Column
• Line
• Pie
• Bar
• Area

There are others, but I will only post about these....

Column Chart

-usually used for showing data changes over time or comparison among items.

Line Chart

-used to display continuous data over time. Useful for showing trends in data at equal intervals.

Pie Chart

-show the size of items in one data series, proportional to the sum of the items. The data points in a pie chart are displayed as a percentage of the whole pie.

Bar Chart

-just a column chart, but the bars are horizontal. Used when the axis labels are long or when the values that are showing are duration.

Area Chart

-emphasize the magnitude of change over time, and can be used to draw attention to the total value across a trend. It is also recommended to use the 3D Area Chart because in 2D Area charts, the data at the back may be hidden.
