What element can you show or hide to improve clarity in the background of the chart?

Solution

✅ Correct Option: 2

Gridlines are the horizontal and vertical lines that appear in the background of a chart to help readers identify and estimate values more accurately.

These lines can be shown or hidden based on the requirement:

  • Showing gridlines helps when precise value estimation is needed from the chart
  • Hiding gridlines creates a cleaner, less cluttered appearance when exact values are not the primary focus

Gridlines directly affect the background clarity of a chart, making them the element that can be toggled to improve visual presentation.


The other options are not background elements:

  • Cell values are data points, not background elements
  • Data types define the format of data (number, text, date) and cannot be visually toggled
  • Legends are reference boxes explaining chart elements, positioned outside the main chart area rather than in the background
