Aggregating data

Visualizing data involves presenting aggregated values of the data you have loaded. In most cases, the data to aggregate is numerical, but also non-numerical data can be aggregated. Examples of aggregated values are sums, averages, counts of occurrences, or results from various statistical calculations.

Note: Some visualizations, like the table visualization, do not support aggregation of values, and sometimes values can be aggregated only on certain axes.

You specify which aggregation to display on an axis in the axis' column selector, .

1. Click the arrow next to the column name in the column selector.
   A popover listing all columns in the data table opens. The selected column is colored.
   
   
2. Click the blue arrow.
   A list of available aggregations opens.
   
   Clicking the arrow (not visible in the example image) at the bottom of the list displays more aggregations.
3. Select the aggregation to display on the axis.
4. Click anywhere outside the popover to close it.
