Method rect_from_values

egui_plot/src/axis.rs:547–555

Transform a rectangle of plot values to a screen-coordinate rectangle. This typically means that the rect is mirrored vertically (top becomes bottom and vice versa), since the plot's coordinate system has +Y up, while egui has +Y down.

(&self, value1: &PlotPoint, value2: &PlotPoint)

    /// bottom and vice versa), since the plot's coordinate system has +Y
    /// up, while egui has +Y down.
    pub fn rect_from_values(&self, value1: &PlotPoint, value2: &PlotPoint) -> Rect {
        let pos1 = self.position_from_point(value1);
        let pos2 = self.position_from_point(value2);

        let mut rect = Rect::NOTHING;
        rect.extend_with(pos1);
        rect.extend_with(pos2);
        rect
    }

    /// delta position / delta value = how many ui points per step in the X axis
    /// in "plot space"
