Changing the size of a chart
You can change a chart’s width and height. If a chart looks too big, you can reduce its width, height, or both. For example, a pie chart that displays few sectors can look oversized. Conversely, increase the size of a chart if items in the chart look too crowded. For example, if a column chart displays many columns, and many of the x‑axis labels do not appear, you can start by increasing the width of the chart to see if all the items fit.
