Column ChartColumn Chart
Use column charts to Display how values change over timeCompare data of single items at specific time intervalsCompare multiple sets of variables of nominal data
Nominal data – e.g.: Territories, individuals etc.
Convention is - data categories on horizontal axis and the values along the vertical axis
Note :If the number of time intervals or units of Nominal data are many, use line charts as the data gets cluttered and the essence of the chat may be lost

Use segmented bars or columns to...Present a part -whole relation over time Show proportional relationships over time Show sub-elements which contribute to the overall column or bar and changes from one period to another.
Segmented column/bar charts are more accurate than pie chart, because distances can be more accurately estimated than areas.

Pie ChartPie Chart
Use pie chart toCompare Parts to Whole at a given point of timeEither the value or Percent to whole can be representedCan plot only one data series as snap shot at a specific timeIdeal only if the number of categories are less than 6
Note : Too many slices in the pie can clutter a pie chart . It is customary to club many small slides in to a category called “Others”. Incase the details are needed , a combination of Pie and a Bar Char are used
