Column Chart

Column chart allows you to compare values for a set of unordered items across categories through vertical bars ordered horizontally.

How to configure the table data to column chart

Column chart need a minimum of one value element and one column element to showcase. The measure column or expression column that you would like to analyze can be dropped into values block. The dimension column that you would like to categorize the measure column can be dropped onto Columns block. If you would like to categorize based on a series column, then the respective dimension column can be dropped onto Rows block in addition. These blocks are composed into Data pane.

The following steps explains the data configuration of column chart:

1. Drag and drop the column chart control icon from the tool box into design panel. You can find the control in tool box by search.
