Scatter Plot Maker

What a scatter plot shows

A scatter plot places one observation at the intersection of two numerical values. It helps reveal direction, shape, spread, and unusual observations in a relationship.

When a scatter chart is useful

Use it when you want to compare paired measurements rather than totals by category. The visible pattern can guide questions for further analysis.

Let the observations lead

1. Keep pairs together. Never sort x and y values independently.
2. State the units. Readers need to know what each axis measures.
3. Check missing values. Do not silently turn missing measurements into zeros.
4. Inspect unusual points. An outlier may be an error or important information.
5. Avoid causal claims. An association alone does not establish a cause.

From a table to plotted points

MyMap can turn supplied paired values into a chart. The example plots twelve ad-spend and revenue pairs with equally sized markers; it does not encode a third variable through bubble size.
