Frequently Asked Questions
- How do I create a scatter chart online for free?
- Enter your X and Y data pairs in the editor above, customize point size and colors, then export as PNG or SVG. No signup or account required.
- What is a scatter chart used for?
- Scatter charts show the relationship between two numeric variables. Each point represents one observation, with its position determined by its X and Y values. They are ideal for spotting correlations, clusters, and outliers.
- What is a trend line on a scatter chart?
- A trend line (or line of best fit) shows the overall direction of the data. Enable it in the controls to see whether your variables have a positive, negative, or no correlation.
- How many data points should a scatter chart have?
- Scatter charts work best with 10 to 500 data points. Too few points make it hard to see patterns; too many can create visual clutter. Adjust the point size to help with dense data.
- What is the difference between a scatter chart and a line chart?
- Line charts connect data points in order to show trends over sequential categories (like time). Scatter charts plot points freely on two numeric axes to show relationships between variables — points are not connected.
- Can I show multiple datasets on one scatter chart?
- Yes. Add multiple datasets and each will render with a distinct color. Enable the legend to label each dataset.
