You may want to set a minimum or maximum value for an axis in your chart.
Here's a list of which types of charts on which you can set the maximum/minimum y-axis / x-axis values:
Vertical bar chart : y-axis only
Triangle bar chart : y-axis only
Horizontal bar chart : x-axis only
Line chart : y-axis only
Area chart : y-axis only
Dot chart : y-axis only
Scatter plot : x-axis and y-axis
To do this, first double-click your chart to edit it. Click the Settings gear in the top right corner of the chart pop-up window.
Then, you can enter the minimum and/or maximum y-axis / x-axis value for your chart.
For the x-axis values, you can increase the width of the chart by clicking and dragging the round handlers on the right or left of the chart. For the y-axis values, you can do the same, increasing the length of the chart by clicking and dragging the round handlers on the top or bottom of the chart. The labels will automatically adjust to the available space.
Currently, the axis minimum or maximum value has to be a round number, for example, 1. It cannot be a decimal or a time-based value.
*Note: Your minimum y-axis value should always be lesser than your maximum y-axis value, and the axis intervals are set according to your data.
