Key Concepts​

Sparkline charts are meant to display trends and their progression in a given date range. They are particular useful, like OHLC and Candlestick charts, for financial scenarios and stock movement analysis. Sparklines display line charts within a grid cell and require:

  • One field to be dropped in the Date placeholder of the data editor.

  • One field to be dropped in Value.

  • One field to be dropped into Category.

When working with Sparkline charts, you can add, modify, or remove information on top of the data you want to display. This comes in the form of:

  • The chart type for your sparkline, which can either be a Line or Area chart.

  • The aggregation for the dates in your chart.

  • The number of values displayed within that same chart.

  • The explicit information you want to include in your sparkline's grid, including whether or not you want to include the last two months in your data and the difference between them.

注記

Sparkline chart displays trends and their progression in the last 12 months by default. You can ajust the date range by using the Sparkline Chart date range settings.
