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

                                                                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.

                                                                 plot chart. It shows the correlations between
                                                                 the two sets of values. The X and Y axes are
