Want to show the labor count as a line chart just below the gantt chart, particular to each timeline it should be correspondent with the above gantt chart timeline.
Hello,
Unfortunately, there is no built-in solution for this, but you can try implementing it using ECharts . You can add it as an overlay using the overlay extension:

Please take a look at this example:

This is not a complete implementation, but it might be useful, and you can modify it to suit your needs.
