Bar and line charts

Use a chart for trends and comparisons over categories: bars, a line, or both on a shared x-axis.

Bar and line chart rendered by vizzy

xychart-beta
  title "Monthly revenue"
  x-axis [jan, feb, mar, apr, may, jun]
  y-axis "Revenue (USD)" 0 --> 12000
  bar  [5000, 6000, 7500, 8200, 9500, 11000]
  line [4800, 6100, 7300, 9000, 9200, 10800]

The first keyword is xychart-beta (or xychart).

x-axis [a, b, c]: the category labels.
y-axis "Title" min --> max: titles the value axis. When both bounds are given they set the value range. Otherwise the plot scales automatically.
bar [...] / line [...]: each adds a series of numbers, matched by index with the x-axis labels. Add as many as you like. A bar and a line together is the most common combination (shown above).

The card widens as the number of categories grows so dense charts stay readable. Unrecognized fields are ignored.

Horizontal orientation

Add horizontal to the xychart-beta line to flip the chart. Categories run top to bottom down the side and values run left to right:

xychart-beta horizontal
  title "Budget by region"
  x-axis [North, South, East, West]
  y-axis "USD" 0 --> 50000
  bar [32000, 18000, 27000, 41000]

In horizontal mode the card grows taller, rather than wider, as the number of categories grows.
