feature_request: Graphs with color band range

[mzakharo]

I use mini-graph-card to maintain chemical levels of my Hot Tub. I need to maintain the chemical levels within a certain range:

There is certainly a better way of doing it, but I managed to get this working by modifying graph.js with the following code:

  getFill(path) {
    let fill = path;
    fill = '';
    fill += 'M0,0';
    fill += ` ${this.width},${this.margin[Y]}`;
    fill += ` ${this.width},${this.height}`;
    fill += ` L 0, ${this.height} z`;
    return fill;
  }

Could support for this type of graph be added to the master repository?
