Polar Bar

polarbar() over named columns of a dataframe_mojo DataFrame (#743). Each argument names a column instead of holding the values. The axis titles default to the categories and values column names.

Usage

from dataviz import polarbar
from dataviz import save

def main() raises:
    var direction: List[String] = [
        "N", "NE", "E", "SE", "S", "SW", "W", "NW",
    ]
    # Illustrative share of observations from each direction; sums to 100%.
    var frequency: List[Int] = [18, 12, 9, 7, 11, 14, 16, 13]

    var c = polarbar(
        direction,
        frequency,
        title="Illustrative Wind Direction Frequency (%)",
    )
    save(c, "docs/src/examples/out_polarbar.svg")
