Pick the right chart

I have {{data}} and I want to show that {{point}}.

Recommend a chart form and say why it fits that specific comparison. Then say what
to put on each axis, whether to index or use raw values, and what to leave off.

Name one chart type that would be the obvious choice and would mislead here, and
say how.

What to fill in

{{data}}

What you have — e.g. daily active users by plan, 18 months

{{point}}

The point you're making — e.g. free users plateau, paid keeps climbing
