Title Is the Finding, Not the Description.
Write the headline that names what changed, not what's plotted.
"Revenue by Quarter" describes the chart; "Revenue grew 31% in Q3, led by Enterprise" describes the finding. Newspaper-style headlines that name the takeaway help readers anchor before they decode - and force the author to actually have a point. If you can't write the headline, the chart probably isn't telling a story yet.
