Answer 1

My solution in June 2019 for needing different colors based on values: Create separate series for the different colors, and use a stacked chart. For example, I needed to create a graph with green bars for passing values and yellow bars for failing values. This was my implementation:

var data = {};
data.legendData = ['Sales','HR','Engineering'];
data.greenSeriesData = ['-',96.38,98.43];
data.yellowSeriesData = [44.23,'-','-'];

var option = {
    title: {
        text: '2019 Progress',
        left: 'center'
    },
    xAxis: {
        type: 'category',
        data: data.legendData
    },
    yAxis: {
        type: 'value',
        axisLabel: {
            formatter: function (val) {
                return (val) + '%';
            }
        }
    },
    series: [{
        data: data.greenSeriesData,
        type: 'bar',
        stack: 'colorbyvalue',
        label: {
            show: true,
            position: 'insideTop',
            formatter: "{c}%",
            color: '#000000'
        },
        barWidth: 50,
        itemStyle: {
            color: 'green'
        }
    },
    {
        data: data.yellowSeriesData,
        type: 'bar',
        stack: 'colorbyvalue',
        label: {
            show: true,
            position: 'insideTop',
            formatter: "{c}%",
            color: '#000000'
        },
        barWidth: 50,
        itemStyle: {
            color: 'yellow'
        }
    }],
    animation: false
};
