Not letting me use gaps button

[Caroline_Zimmerman]

How can I allow my excel to let me use the gaps feature? I want the whole month to show for my graph, but want the line to stop at the month I am working on.

It depends on the chart type. The Gaps option is disabled for

• Stacked Line Chart
• 100% Stacked Line Chart
• Stacked Area Chart
• 100% Stacked Area Chart

and perhaps more.
