When you create a Line Chart or an Area Chart to be used in a Panel, you can add grid lines to the chart, and also customize how those grid lines are displayed.
To show grid lines:
- On the Search page, in the Aggregation tab, click the Settings icon and select Grid Lines.
- Select Enable grid lines. By default, the check boxes For X axis and For Y axis are selected, and automatic (default) grid lines are used in the chart. The default should satisfy most use cases, but you can customize how the grid lines are displayed.
- X or Y Axis. You can select or deselect the check boxes For X axis and/or For Y axis.
- Grid Line Interval. Enter a positive numeric value for the frequency that you want to see the grid lines in relation to the query and the data it has returned. (For a timeslice X axis, the unit is seconds. For example, if you enter X interval = 4, grid lines will appear every 4 seconds.)
For the Y axis in the example below, the data ranges from 0 to 2,560 and shows default grid lines at 0, 640, 1,280, 1,920, and 2,560. So if you want to see 10 grid lines between 0 and 2,560, divide 2,560 by 10 (2560/10 = 256). For the Y axis Grid Line Interval enter 256, and you will see 10 grid lines between 0 and 2,560.
- Grid Line Color. To modify the grid line color, you can use:
- A six digit hexadecimal code, for example, #00FF00.
- A simple string, such as red or blue.
- An RGB value, like rgb(0,255,0).
- Click Save.
