title: How to change z-index of chart js tooltip?
body: <p>I have 4 charts placed side by side using bootstrap's grid system. One of the chart's width is just one col wide (col-md-1), which uses bubble chart(simply shows circles from top to bottom). However, when I hover on the bubble, the tooltip gets truncated. I tried to change z-index of the div inside which the chart element is placed, but that did not solve the problem. </p>
  
  <p>This is how it shows up on mouse over:

  <p>Kindly let me know how can I change the z-index of the tooltip element.</p>

  <pre><code>&lt;div class="container-fluid"&gt;
          &lt;div class="row"&gt;
              &lt;div class="col-md-5 col-sm-5 col-xs-5"&gt;
                  col 5
              &lt;/div&gt;
              &lt;div class="col-md-1 col-sm-1 col-xs-1"&gt;
                  &lt;div style="height: 60vh;"&gt;
                      &lt;canvas id="can" /&gt;
                  &lt;/div&gt;
              &lt;/div&gt;
              &lt;div class="col-md-6 col-sm-6 col-xs-6"&gt;
                  col 6
              &lt;/div&gt;
          &lt;/div&gt;
      &lt;/div&gt;
