The ''library'' hash gets [[https://stackoverflow.com/questions/57719975/force-display-of-ticks-on-xaxes-using-chartkick-gem-and-chart-js|passed through]] ''Chartkick'' to ''chart.js''.

For some reason axes need to be labelled ''xAxes'' (can be(?) an array for multiple x axes) rather than just ''x'' as [[https://www.chartjs.org/docs/latest/axes/cartesian/|in the chart.js docs]].

<code ruby>
def model_helper(data)
  line_chart(
    data,
    title: 'Chart title',
    ## Axes
    min: 10, # default 0 if no non-zero points
    max: 100,
    xtitle: 'Time',
    ytitle: 'Lolz',
    
    ## CSS
    id: 'lolchart',
    
    ## Appearance
    height: '500px',
    colors: COLORS,
    points: false,
    
    # Key
    legend: :bottom,
    
    ## No idea why these have to be in a hash:
    library: {
      spanGaps: true,
      lineTension: 0.5, # Values between 0 and 1-ish seem to do something
      curve: true, # false = straight line segments
      scales: {
        xAxes: [{
          display: false,
          ticks: {
            maxTicksLimit: 5,
          },
          # Can't get anything else to work here
        }
      }
    }
  )
end
