Multi-Series Chart

You can create a stacked bar chart comparing multiple metrics (Multi Y-axes) grouped by the same X-axis. Each stack component represents one Y-axis metric. 

1. Follow the below steps to create a multi-series stacked bar chart.
   
2. Open the chart editor. Drop columns as given below.
   
   • X-Axis shelf - Drop the dimension column to categorize the data
     
   • Y-Axis shelf - Drop multiple metric columns
     
3. Click the Click here to Generate Graph button. A multi-series bar chart will be created.
   
4. Merge Axes and select the chart type as a Stacked Bar.

Horizontal Chart

In the Horizontal Chart, data series is represented by horizontal bars. This looks better when a chart having quite a few bars is being viewed on a narrow layout, like on a mobile. 

Follow the below steps to create a Horizontal stacked bar chart.

1. Open the chart editor. Drag and drop columns as given below.
   
   • Y-Axis shelf - Drop the dimension column (to categorize the data)
     
   • X-Axis shelf - Drop the metric column
     
   • Color shelf - Drop the column to categorize by color
     
2. Click the Click here to Generate Graph button. A horizontal stacked bar chart will be created.

100 % Stacked Bar

100% Stacked Bar plots the contribution of each category in the percentage of the total in a group, assuming the total in a group is 100%. You must select the Base field by which grouping will be done. 

Follow the below steps to create a 100% stacked bar chart.

1. Open the chart editor. Drag and drop columns as given below.
   
   • Y-Axis  self - Drop the dimension column (to categorize the data)
     
   • X-Axis  self - Drop the metric column
     
   • Color  self - Drop the column to categorize by color
     
2. Once you add all columns, set the summary function of the metric column as 100% Group . 
   
3.  The Show Data As Settings: 100% Group dialog will open. Select a base column to group the value. This column is considered as the whole (100%) and the contribution of each category is calculated based on this.  
   
4. Click the Click here to Generate Graph button. A horizontal stacked bar chart will be created.

• Aggregate: A column with an aggregate function (sum, average, count, etc) applied over it. This also includes the aggregate formula columns.
