A grouped bar chart, also known as clustered bar chart or multi-series bar chart extends the bar chart, plotting numeric values for levels of two categorical variables instead of one. You can create a grouped column chart for illustrating your sales cycle using EdrawMax Online. The free column chart maker offers free built-in templates that ease down your creation of the chart diagrams. It also comes with over 26,000 symbols that help you create logically correct column charts for your sales and marketing needs. It should be noted here that in a stacked column chart, data series are stacked one on top of the other in vertical columns. Stacked column charts can show change over time because it is easy to compare total column lengths.
