Short answer

Choose a line chart for change over time, bars for comparing categories, and a scatter plot for the relationship between two numeric variables. Put the target in the chart when it changes the decision, and remove decorative elements that do not help the reader compare values.

  • Start with the analytical question, not the chart menu.
  • Bar-chart axes should normally begin at zero because length encodes value.
  • Use direct labels and a clear title that states the measure and period.

Match visual form to the comparison

A line chart preserves the sequence of time and makes trends visible. A sorted horizontal bar chart helps compare many category names. A scatter plot shows whether two measures move together and can reveal clusters or outliers.

Pie and doughnut charts become difficult to compare when there are many categories or similar slices. A bar chart usually makes those differences easier to judge.

Show context without clutter

A KPI has meaning relative to a target, prior period, or expected range. Add that comparison directly. Avoid 3D effects, heavy borders, and legends that force the reader to look back and forth when direct labels would work.

  • Use the same scale for small multiples that should be compared.
  • Do not use a second axis unless the relationship is clear and unavoidable.
  • Write units in the title or axis label, including whether values are counts, dollars, or percentages.

Report weekly activation against a target

Activation rate is recorded weekly and the target is 35%.

  1. Create a line chart with Week on the horizontal axis and Activation rate on the vertical axis.
  2. Add a second series that repeats the 35% target for every week.
  3. Format the target as a quiet reference line and label the latest actual value.
Result: The reader can see the trend, current performance, and target gap in one view.

Common mistakes

  • Using a line chart for unordered categories.
  • Truncating a bar-chart axis so a small difference appears dramatic.
  • Plotting too many series until no line can be followed.
  • Using two vertical axes that imply a relationship created by scale choices.
