Use Chart



                              A chart is a graphical representation of data, in which "the data is represented by symbols, such as bars in a bar chart, lines in a line chart, or slices in a pie chart". 
                              A chart can represent tabular numeric data, functions or some kinds of qualitative structure and provides different info.

The term "chart" as a graphical representation of data has multiple meanings:

• A data chart is a type of diagram or graph, that organizes and represents a set of numerical or qualitative data.
• Maps that are adorned with extra information for some specific purpose are often known as charts, such as a nautical chart or aeronautical chart.
• Other domain specific constructs are sometimes called charts, such as the chord chart in music notation or a record chart for album popularity.
• Charts are often used to ease understanding of large quantities of data and the relationships between parts of the data. 
• Charts can usually be read more quickly than the raw data that they are produced from. They are used in a wide variety of fields, and can be created by hand (often on graph paper) or by computer using a charting application.

  • A bar chart is a chart with rectangular bars with lengths proportional to the values that they represent. The bars can be plotted vertically or horizontally.
  • A pie chart shows percentage values as a slice of a pie.
