title: Removing "Series 1" in legend and ordering legend
body: <p>I am creating a funny jigsaw puzzle curve and want to know the following from how I wrote the code below:</p>
  
  <p>Dataset</p>
  
  <pre><code>Zone &lt;- c('Overwhelm State', 'Overwhelm State', 'Puzzle Pairing State', 
    'Puzzle Pairing State', 'Puzzle Pairing State', 'Puzzle Pairing State', 
    'Puzzle Pairing State', 'Puzzle Pairing State', 'Puzzle Pairing State',
    '"I can do this" State', '"I can do this" State', '"I can do this" State',
    'Lost State','Lost State','Lost State','Lost State', 'Close Out State',
    'Close Out State', 'Close Out State','Close Out State', 'Close Out State', 
    'Close Out State')
  
  `Jigsaw Puzzle Pieces`&lt;- c(0.20, 0.10, 0.20, 0.40, 0.80, 1.60, 3.20, 
  6.40, 12.80, 14.00,15.00, 18.00, 31.85, 33.50, 33.50, 31.85, 15.93, 
  7.96, 3.98, 1.99, 1.00, 0.50)
  
  Date &lt;- as.Date(c('2020-03-28','2020-03-29','2020-03-30','2020-03-31',
    '2020-04-01','2020-04-02','2020-04-03','2020-04-04','2020-04-05','2020-04-06',    '2020-04-07','2020-04-08','2020-04-09','2020-04-10','2020-04-11','2020-04-12',
    '2020-04-13','2020-04-14','2020-04-15','2020-04-16','2020-04-17','2020-04-18'))
  
  jigsaw_data &lt;- data.frame(Date, `Jigsaw Puzzle Pieces`, Zone)
  </code></pre>
  
  <p>1) How do I change the font size of the title?</p>
  
  <p>2) How do I remove the value "Series 1" from the legend but keep the line appearing on the graph?</p>
  
  <p>3) How do I order the legend so that it is: </p>
  
  <pre><code>"Overwhelm State"
  "Puzzle Pairing State"
  "I can do this" State
  "Lost State"
  "Close Out State"
  </code></pre>
  
  <p>Code below:</p>
  
  <pre><code>library(highcharter)
  highchart() %&gt;%
    hc_add_series(jigsaw_data, type = "line", lineWidth = 10,
                 hcaes(x = Date, y = `Jigsaw Puzzle Pieces`)) %&gt;%
    hc_add_series(jigsaw, type = "column",
                 hcaes(x = Date, y = `Jigsaw Puzzle Pieces`, group = Zone)) %&gt;%
    hc_xAxis(type = 'datetime', labels = list(format = '{value:%b %d}')) %&gt;%
    hc_title(text = "&lt;b&gt;Jigsaw Puzzle Modelling Curve&lt;/b&gt;") %&gt;%
    hc_subtitle(text = "&lt;b&gt;COVID-19 Bias&lt;b&gt;") %&gt;%
    hc_xAxis(title = list(text = '&lt;b&gt;Quarantine Period&lt;b&gt;',lineWidth = 3)) %&gt;%
    hc_yAxis(title = list(text = '&lt;b&gt;Time Required to Insert One Puzzle Piece&lt;b&gt;')) %&gt;%
    hc_legend(align = "right", verticalAlign = "top",
              layout = "vertical", x = 0, y = 100) 
  </code></pre>
