# xan heatmap ```txt Draw a heatmap from CSV data. Use the --show-gradients flag to display a showcase of available color gradients. Usage: xan heatmap [options] [] xan heatmap --show-gradients xan heatmap --green-hills xan heatmap --help heatmap options: -G, --gradient Gradient to use. Use --show-gradients to see what is available. [default: or_rd] -m, --min Minimum value for a cell in the heatmap. Will clamp irrelevant values and use this min for normalization. -M, --max Maximum value for a cell in the heatmap. Will clamp irrelevant values and use this max for normalization. --normalize How to normalize the heatmap's values. Can be one of "full", "row" or "col". [default: full] -S, --size Size of the heatmap square in terminal rows. [default: 1] -D, --diverging Use a diverging color gradient. Currently only shorthand for "--gradient rd_bu". --cram Attempt to cram column labels over the columns. Usually works better when -S, --scale > 1. -N, --show-numbers Whether to attempt to show numbers in the cells. Usually only useful when -S, --scale > 1. --color When to color the output using ANSI escape codes. Use `auto` for automatic detection, `never` to disable colors completely and `always` to force colors, even when the output could not handle them. [default: auto] --show-gradients Display a showcase of available gradients. Common options: -h, --help Display this message -n, --no-headers When set, the file will be considered as having no headers. -d, --delimiter The field delimiter for reading CSV data. Must be a single character. ```
