Histogram

Histograms show the distribution of continuous values as binned counts. Use for single-gene expression distributions.

Supported Commands

• study query --type expression --chart histogram

Examples

# ERBB2 expression histogram in terminal
biomcp study query --study brca_tcga_pan_can_atlas_2018 --gene ERBB2 --type expression \
  --chart histogram --terminal

# Write to SVG
biomcp study query --study brca_tcga_pan_can_atlas_2018 --gene ERBB2 --type expression \
  --chart histogram -o erbb2-expr.svg

Notes

Bins default to 30. The histogram reads raw expression values from the study matrix file.
