title: How to draw continues lines across panels in Tableau
body: <p>I want to plot a couple of measures by months over the last three years. The plot would be divided by year. So I put <code>year</code> and <code>month</code> for columns and the measure values for rows. The <code>year</code> is defined as <code>DATEPART('year', [Month Date])</code> and <code>month</code> is <code>DATEPART('month', [Month Date])</code>.</p>
  
  <p>The plot looks like this.

  <p>The lines are broken between years. Both <code>YEAR</code> and <code>MONTH</code> are blue (discrete), but if I change them to green (continuous), the lines are connected but it looks weird.

  <p>I wonder how to make continuous lines across year?</p>
