LINE CHART
                  A line chart is a type of graph that displays

                  continuous  data  at  regular intervals. It is
                  generally used to highlight the changes that
                  take  place  in a value through  a specified
                  period of time. It is also known as a frequency
                  polygon.

                                                                      An  area chart displays  the  quantitative
                                                                      magnitude of the data graphically over the
                                                                      course of time. It also depicts the relationship
                                                                      of parts to a whole by displaying the sum of
                                                                      plotted values. The area chart emphasises the
                                                                      area between the line and the axis with the

                                                                      help of the colours, textures, hatchings, etc.
                                                                      These charts are based on the features of the
                                                                      line chart.


                  PIE CHART
                  A pie chart is shaped like a circle divided into
                  slices, each slice showing the relative size of

                  each  value. The pie  chart  only  displays  one
                  data series in the form of comparative charts.
                  It is  useful when you  want  to  emphasise  a
                  significant element.

                                                                       A scatter chart is also known as XY scatter
                                                                       plot chart. It shows the correlations between
                                                                       the two sets of values. The X and Y axes are
                                                                       used to represent the data plots on the chart.
