<p>With the threshold plugin, you can apply a specific color to the part of a data series below a threshold. This is can be useful for highlighting negative values, e.g. when displaying net results or what's in stock.</p>

<button>Threshold at 5</button>
<button>Threshold at 0</button>
<button>Threshold at -2.5</button>
