Single & MultiSeries Bar ChartsLike in Column Charts, Bar Charts can also have one or more Data Series. In case of more than one series, Data Points from different Series are placed next to one another and are differentiated by their color.
Stacked Bar ChartsStacked Bar Charts have data points stacked one on top of the other instead of placing them side-by-side. This allows you to compare the contribution of different data series to the total at a given point. You should use Stacked bar when multiple data-series can be added up to show combined result like total sales of various products, etc.
Stacked Bar 100%In case of Stacked Bar 100% Charts, data points are stacked similar to “Stacked Bar” except that their individual height is calculated as a percentage of total sum. This allows you to compare individual contribution of Data Series to the whole.
