### Show
<!-- prettier-ignore-start -->
Choose how much information to show.
| Option | Description |
| ------ | ----------- |
| Show | Set how much information to show. Choose from:<ul><li>**Calculate** - Reduces each value to a single value per series.</li><li>**All values** - Displays every value from a single series.</li></ul> |
| Calculation | If you chose **Calculate** as your **Show** option, select a calculation to reduce each series. For information about available calculations, refer to [Calculation types](ref:calculation-types). |
| Limit | If you chose **All values** as your **Show** option, enter a value to limit the number of values displayed. |
| Fields | Select which field or fields to display in the visualization. Each field name is available on the list, or you can select one of the following options:<ul><li>**Numeric fields** - All fields with numerical values.</li><li>**All fields** - All fields that are not removed by transformations.</li><li>**Time** - All fields with time values.</li></ul> |
- **Calculate -** Reduces each value to a single value per series.
- **All values -** Displays every value from a single series.
