Chartio gives you the option to add horizontal or vertical rulers to your Dashboard, which you can resize and arrange as desired. Rulers are great for visually grouping similar Charts together to organize your Dashboard.
To add a ruler:
1. Click the + Add Ruler button in the upper-right corner of your Dashboard. Select your line weight and whether you want a Horizontal or Vertical ruler from the modal.
2. The new ruler will be added to your Dashboard, and you can drag the ruler to the desired position. Place your cursor over the end of the ruler (right end for horizontal, bottom for vertical) to resize the ruler.
