Getting Started

===============

Welcome to PlotFX! This page will guide you through creating a simple first plot

and then give you pointers to more in-depth documentation.

This page will guide you through creating a simple first plot and then give you

pointers to more detailed documentation.

### The first image

A minimal example file for PlotFX is this one:

    width: 1200px;

    height: 600px;

    points {

      xs: 10px 40px;

      ys: 20px 400px;

      colors: #06c #c06;

    }

Save this to `example.ptx` and run it using the command line below:

    plotfx --in example.ptx --out example.svg

If you do that, PlotFX will produce a white 1200x600 pixel image with two coloured

dots:

    [ image ]

It's not the most useful example in the world, but it shows how to run files

through PlotFX and illustrates that PlotFX is in a way more similar to a drawing

tool like Inkscape than to a chart generator.

### Parametric drawing

### Adding a scale, title and legend

### Diving deeper

----

[![A simple line chart](./examples/linecharts/simple_timeseries.svg)](./examples/linecharts/simple_timeseries)

The simple line chart from above was generated with PlotFX using the following

command line:

    $ plotfx --in example_chart.ptx --out example_chart.svg

Here is the input file from which the above plot was generated (`example_chart.ptx`):

    width: 1200px;

    height: 280px;

    scale-y-min: 0;

    scale-y-max: 140;

    lines {

      xs: csv('measurement.csv', time);

      ys: csv('measurement.csv', value2);

      colors: #06c;

    }

    axis {

      position: bottom;

      format: datetime("%H:%M:%S");

    }

    axis {

      position: left;

      layout: linear(20);

    }
