Creating a Future Prediction Graph with ECharts

I am looking to create a forecast chart that includes both Actual values (presented as a line chart) and projected values (displayed as a dotted chart). An example of what I have in mind can be seen here, created using Excel: https://i.sstatic.net/q18An.png

Although I couldn't locate a ready-made example on the ECharts library website , I am determined to achieve this chart with their tools.

If anyone has suggestions or guidance on how to construct this type of chart using javascript, I am open to exploring alternative libraries such as ChartJs. Any help would be greatly appreciated!

Answer №1

give this a try.

example = {
xAxis: {
    type: 'category',
    data: [20, 19, 18, 17, 16, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1]
},
yAxis: {
    type: 'value'
},
series: [{
    data: [0, 20, 30, 45, 40, 50, 51, 52, 50, 49, 56, 55],
    type: 'line',
    smooth: true,
    lineStyle: {
        color: 'red'
    }
}, {
    data: [null, null, null, null, null, null, null, null, null, null, null, 55, 50, 49, 48],
    type: 'line',
    smooth: true,
    lineStyle: {
        color: 'blue',
        type: 'dashed'
    }
}]

};

This is a straightforward example that should help with your problem. I omitted adding the legend, but you can easily do it on your own.
