Struct DfPlot 

pub struct DfPlot<'a> { /* private fields */ }

A builder produced by DataFramePlotExt::plot. Terminal methods (line, scatter, hist, bar) consume the builder and return a fully built Figure, ready to .save(...) via the umbrella crate’s FigureExt.

Implementations

impl DfPlot<'_>

pub fn size(self, width: u32, height: u32) -> Self

Sets the output figure size in pixels (default 800x600).

pub fn color_by(self, column: &str) -> Self

Splits the data into one labelled series per distinct value of column (categorical grouping, like seaborn hue). Applies to line/scatter.

pub fn line(self, x: &str, y: &str) -> Result<Figure, PlotError>

Plots y against x as a line chart.

pub fn scatter(self, x: &str, y: &str) -> Result<Figure, PlotError>

Plots y against x as a scatter chart.

pub fn hist(self, column: &str, bins: usize) -> Result<Figure, PlotError>

Draws a histogram of a single numeric column.

pub fn bar(self, category: &str, value: &str) -> Result<Figure, PlotError>

Draws a bar chart with string categories from category and heights from the numeric column value.
