DESCRIPTION
      The plot_time_series is a simple utility for plotting a time series graph using R.
      This is useful for e.g. plotting KPI values over time.
      The graph is drawn as a scatterplot with a LOESS fit line of variable smoothness.

OPTIONS
      The options are as follows:

      --verbose                    Get a little chatty?
      --width                      The width of the graph in pixels
      --height                     The height of the graph in pixels
      --csv_filename               A CSV containing input data with columns date,value (example below)
      --output_filename            The file that the graph is written to
      --special_points_filename    A file containing special points e.g. milestones or targets
      --special_points_color       The color of the special points
      --title                      The title shown above the graph
      --y_title                    The title shown on the y axis of the graph
      --y_unit                     A string appended to the y axis values e.g. MM
      --y_prefix                   A string prepended to the y axis values e.g. $
      --y_range                    Manually set Y axis limits e.g. 10:1000
      --x_range                    Manually set X axis limits e.g. 04/27/2012:05/20/2013
      --x_spacing                  How the x-axis is spaced e.g. day, 3 days, week, month, 2 weeks, 2 months
      --y_line                     Add a horizontal labeled line at a Y value e.g. "10,000:Target for 2012"
      --point_color                The color to draw points in
      --sunday_point_color         The color to draw sunday points in
      --input_date_format          The format of the date in the datafile, default is "%m/%d/%Y"
      --axis_color                 The color to use for the axis
      --smoothness                 How much to smooth the LOESS fit line. Float between 0 and 1
      --plot_out_of_range          Plot out of range points and use them in the interpolation?
      --trim_to_week               Trim the X axis to whole weeks? (x grid goes Sunday to Sunday)
      --show_gridlines             Show gridlines?
      --label_cex                  Graph label scaling relative to default, used for y_line and special_points

        --output_filename=output/unbranded_organic_registrations.png --title="Unbranded Organic Registrations: %s to %s"
        --y_title="Number Registrations"
