Make a grouped, stacked or overlaid bar chart with plot_ly()

Draws one bar trace per row of matrix, coloured and legended by row, with columns along the x axis. Used by the barplot module, and by interactive_count_barplot to render feature-annotation category counts.

Usage

interactive_barchart(
  matrix,
  barmode = c("stack", "group", "overlay"),
  ylab = "",
  palette_name = COLORBLIND_PALETTE_NAME,
  title = NULL
)

Arguments

matrix: A matrix to plot, e.g. counts by category (row) and sample (column)
barmode: 'stack' (default), 'group' or 'overlay'. For 'overlay', rows are reordered by decreasing mean so each is more likely to be visible
ylab: Y axis label
palette_name: Valid R color palette name
title: Plot title

Value

output A plotly htmlwidget

Examples

m <- matrix(1:6, nrow = 2, dimnames = list(c("up", "down"), c("s1", "s2", "s3")))
interactive_barchart(m, barmode = "stack", ylab = "Count")
