What Is a Renko?

This chart turns structured data into a visual pattern that is faster to scan than a raw table.

Use it when the reader should understand shape, comparison, distribution, proportion, or movement quickly.

Start With the Raw Data

Most charts begin with a small, structured table before the visual layer is added:

Label Value A Value B
Example 1 24 31
Example 2 30 28
Example 3 18 36

The raw values stay the same, but the visual structure makes patterns easier to spot: highs, lows, clusters, gaps, and unusual changes.

Frequently Asked Questions

When should I trim the number of values?

Too many points overwhelm viewers. Keep x-axis labels readable and rumble the data into summary points when possible.
