signalsmith::plot::PlotStyle Class Reference

#include <plot.h>

Detailed Description

Plotting style, used for both layout and SVG rendering.

Colour/dash/hatch styles are defined as CSS classes, assigned to elements based on their integer style index. CSS is written inline in the SVG, and can be extended/overridden with .cssPrefix/.cssSuffix.

It generates CSS classes from .colours (svg-plot-sN/svg-plot-fN/svg-plot-tN for stroke/fill/text), .dashes (svg-plot-dN) and .hatches (svg-plot-hN), where N is the index - e.g. there are six colours by default, generating svg-plot-s0 to svg-plot-s5.

animation

double signalsmith::plot::PlotStyle::animation = 2

Animation duration.

fontAspectRatio

double signalsmith::plot::PlotStyle::fontAspectRatio = 1

scales size estimates, if using a particularly wide font

markers

std::vector<std::string> signalsmith::plot::PlotStyle::markers

Initial value:

= {
        "<circle cx=\"0\" cy=\"0\" r=\"1\" stroke=\"none\"/>",
        "<path d=\"M0 0.9 -0.9 0 0 -0.9 0.9 0Z\" fill=\"#FFFA\" stroke-linejoin=\"miter\" stroke-width=\"0.5\"/>",
        "<path fill=\"none\" d=\"M0 -1.2 0 1.2 M -1.2 0 1.2 0\" stroke-width=\"0.6\"/>",
        "<circle cx=\"0\" cy=\"0\" fill=\"#FFFA\" r=\"0.82\" stroke-width=\"0.55\"/>",
        "<path stroke=\"none\" d=\"M0 -1.25 1.25 0.9 -1.25 0.9Z\"/>",
        
        
        
    }

SVG literals for the markers. These should be centered on (0, 0) and look correct next to a filled circle of radius 1. They will be given both a stroke and fill-class, so they should specify fill="none"/stroke="none" if fill/stroke is not wanted.

scale

double signalsmith::plot::PlotStyle::scale = 1

scales the entire plot (including adjusting the precision)
