title: Hide/disable tootlip on specific graph values
body: <p>I have a bar graph with chartjs 2.</p>
  
  <p>I would like to hide tootlips when bar value is egal to a number ( in my exemple 8.23 )</p>
  
  <p>I havn't found an option on chartjs to disable tooltips when hover a specific value </p>
  
  <pre><code>tooltips: {
          enabled: true,
          yPadding: -2,
          xPadding: 10,
          titleFontColor: 'rgba(0, 0, 255, 0.0)',
          displayColors: false,
          borderWidth: 1,
          bodyFontSize: 16,
          bodyFontFamily: 'Avenir',
          backgroundColor: '#0088ce',
          borderColor: '#d7d7d7',
          bodyFontColor: '#FFF',
          callbacks: {
              label: (tooltipItem: any, data: any) =&gt; {
                  if (this.type === 'PRODUCTION') {
                      return 'condition result';
                  } else {
                      return ' condition result2';
                  }
              },
          }
