Use the zero baseline setting when showcasing positive and negative values in a chart. This option is available in line, bar, column, area, multiple axis, scatter, bubble, and financial charts. Depending on the chart type you are using, you can have a horizontal zero baseline or a vertical zero baseline.
To enable the zero baseline:
❶ Select the chart with a click.
❷ In the Axis & Grid tab of your chart settings, in the Grid dropdown, choose None, Vertical or Horizontal.
Note: The horizontal zero baseline or vertical zero baseline setting will appear when you choose to display the gridline perpendicular to the axis.
❸ Enable the horizontal zero baseline or vertical zero baseline setting.
