title: Plots.jl adding a trendline, plus changing the x-axis
body: <p>I want to do a simple plot using Plots.jl.</p>
  
  <p>I calculated a rate for each month over a couple of years. The problem that I am facing now is that I want to add a trendline to this plot. I did not find how this is done in Julia or Plots, if this is somewhere, please tell me.</p>
  
  <p>My second question is that as I just get a vector with lets say 150 elements, each for a month, Plots.jl just gives me numbers on the x-axis for 0, 50, 100 and 150 with horizontal lines. I would like to change this to every 12 numbers one of these lines plus the year as a label on the axis.</p>
  
  <p>I hope my question is clear, and thank you very much in advance.</p>
  
  <p>Cheers </p>
