SvgCharts

SVG chart renderer for Elixir powered by charts-rs.

Supports bar, line, pie, radar, scatter, candlestick, heatmap, table, and multi-chart types.

Installation

def deps do
  [{:svg_charts, "~> 0.5.1"}]
end

Usage

{:ok, svg} = SvgCharts.render(%{
  "type" => "bar",
  "title_text" => "Downloads",
  "series_list" => [
    %{"name" => "MDEx", "data" => [120.0, 200.0, 150.0]}
  ],
  "x_axis_data" => ["Jan", "Feb", "Mar"]
})

Legend layout

Chart options are passed through to charts-rs. When a chart has a title or subtitle, use legend_margin to leave room above the legend:

"legend_margin" => %{"top" => 60}

The margin accepts top, right, bottom, and left values. To omit the legend, which is often useful for a single-series chart, use:

"legend_show" => false

See the charts-rs documentation for the full JSON configuration options.
