Generates a Histogram plot

Example

// import
use plotpy::*;
use std::path::Path;

// directory to save figures
const OUT_DIR: &str = "/tmp/plotpy/doc_tests";

// set values
let values = vec![
    vec![1, 1, 1, 2, 2, 2, 2, 2, 3, 3, 4, 5, 6], // first series
    vec![-1, -1, 0, 1, 2, 3],                    // second series
    vec![5, 6, 7, 8],                            // third series
];

// set labels
let labels = ["first".to_string(), "second".to_string(), "third".to_string()];

// configure and draw histogram
let mut histogram = Histogram::new();
histogram.draw(&values, &labels);

// add histogram to plot
let mut plot = Plot::new();
plot.add(&histogram);
plot.legend();
plot.grid_and_labels("values", "count");

// save figure
let path = Path::new(OUT_DIR).join("doc_histogram.svg");
plot.save(&path)?;

Fields

colors: Vec<String>

Colors for each bar

style: String

Type of histogram; e.g. “bar”

bar is a traditional bar-type histogram. If multiple data are given the bars are arranged side by side.
barstacked is a bar-type histogram where multiple data are stacked on top of each other.
step generates a lineplot that is by default unfilled.
stepfilled generates a lineplot that is by default filled.

As defined in https://matplotlib.org/stable/api/_as_gen/matplotlib.pyplot.hist.html

stacked: bool

Draws stacked histogram

no_fill: bool

Skip filling bars

number_bins: i32

Number of bins
