Parallel Coordinates

A parallel-coordinates chart.

Usage

from dataviz_mojo import parallel
from dataviz_mojo.plot import save

def main() raises:
    var dims: List[String] = ["Horsepower", "MPG", "Weight (100 lbs)", "0-60 (sec)", "Price ($k)"]
    var row_names: List[String] = ["Sedan", "SUV", "Sports Car"]
    var data: List[List[Float64]] = [
        [180.0, 32.0, 30.0, 8.5, 28.0],
        [280.0, 22.0, 45.0, 6.5, 42.0],
        [450.0, 16.0, 34.0, 3.5, 85.0],
    ]

    var c = parallel(data, dims, row_names)
    save(c, "docs/src/examples/out_parallel.svg")

Args:

• data: data[row] is row_names[row]’s polyline, one value per dims entry.
• dims: One vertical axis per entry, each independently scaled to its own column’s [min, max] across data.
• row_names: One polyline per entry, used as the legend key; required (not auto-numbered).
• theme: Full styling knobs beyond this function’s own parameters (colors, margins, fonts, gridlines, …) – see Theme’s docstring.
• width: Pixel width of the returned Plot (.size()).
• height: Pixel height of the returned Plot (.size()).
• title: The chart’s title, shown above the plot.
• subtitle: A secondary line shown under the title.
• x_title: The x-axis caption.
• y_title: The y-axis caption.
