Make a scatter plot online
A scatter plot shows whether two measurements move together — height and weight, advertising and sales, study time and grades. Paste pairs of numbers and the points appear as you type, with a trend line that puts the relationship into numbers.
How to make a scatter plot
- Paste or type one row per point: x, y — or a label first (label, x, y). Copy straight from Excel or Google Sheets, or type it with commas.
- A first row of names labels the axes; a last column of group names colours the points by group, with a legend.
- Turn on the trend line, the point labels, or axes that start at zero, and set the point size and opacity.
- Set the title, colours and image size, then download a PNG, JPG or SVG, or copy the image.
Reading a scatter plot
- Points rising from left to right suggest a positive relationship; falling, a negative one. A cloud with no direction suggests no linear relationship.
- The trend line is the least-squares straight line through the points. Its equation, y = ax + b, predicts y from x, and R² (from 0 to 1) shows how closely the points follow it.
- A relationship isn’t proof that one thing causes the other.
- To show a third value as the size of each point, use the Bubble Chart Maker; for values over time, the Line Chart Maker.
