A column chart is a graphical representation or visualization of measured data in the form of vertical rectangular bars or columns plotted along two axes with the values representing the measure of that particular category of data. The values are generally expressed in units relating to the problem statement or in percentages. These types of charts are mostly useful for statistical comparison of data. A clustered column chart is useful for comparing value between different categories, each having several sub-categories. The following template is Clustered/ Grouped Column Chart.
