Use Spark Charts to Examine Trends

You can add a spark chart to a tile visualization to view aggregate data trends over time.

1. Open or create a project and click Visualize.
2. In the Data pane, drag an aggregate data element to the canvas to create a tile visualization. For example, select Revenue.
3. In the Data pane drag a time-based data element to Category (Chart) to add a spark chart to the tile visualization. For example, select and drag Month.

   The red dot on the spark chart line shows the lowest value, and the green dot shows the highest value. The tooltip shows the first, last, lowest, highest and average aggregate values for the selected category. Hover your cursor anywhere over the spark chart to display the tooltip.

4. If you want to add a filter, drag a data element from the Data pane to Click here or drag data to add a filter.
   For example, Year.

   The filter changes the spark line to show the trend for the filtered data.
