chartist-plugin-tooltip

Implements a tooltip for Chartist charts.

Install

As styles are very different with each project, no CSS is included. You can copy paste this to use as base:

.ct-tooltip {
    position: absolute;
    display: inline-block;
    min-width: 5em;
    padding: 8px 10px;
    background: #383838;
    color: #fff;
    text-align: center;
    pointer-events: none;
    z-index: 100;
    transition: opacity .2s linear;
 
    // Arrow 
    &:before {
        position: absolute;
        bottom: -14px;
        left: 50%;
        border: solid transparent;
        content: ' ';
        height: 0;
        width: 0;
        pointer-events: none;
        border-color: rgba(251, 249, 228, 0);
        border-top-color: #383838;
        border-width: 7px;
        margin-left: -8px;
    }
 
    &.hide {
        display: block;
        opacity: 0;
        visibility: hidden;
    }
}
