Add a sparkline to a KPI card.

You need a numeric line item in a module with two levels in the time dimension, selected as Data source in the Card configuration panel.

To show a KPI card's Card configuration panel, either:

• When you create a new KPI card, click the Configure KPI button, or
• Select or hover over an existing card on your page and click the Edit icon.

To add a sparkline to a KPI card and configure it, 

1. In the Card configuration panel, select the KPI tab.
2. Expand Sparkline and enable the Enabled toggle.
3. Optionally, you can:
   • Enable the Data labels toggle.
     When Data labels is enabled, a data label displays when you hover over a data point in the chart. 
   • Change the color of the sparkline.
     A color picker displays next to the Sparkline color label. Click on the color picker and select a color from the palette.
