Hi,
Is there any way to display the scale by days number instead of date?
Just like this picture
Hello,
One of the options is to use gantt.scales.config
with format
function that expects a date object as a parameter:
https://docs.dhtmlx.com/gantt/api__gantt_scales_config.html ;
You can get the configuration of the time scale by getScale
method:
https://docs.dhtmlx.com/gantt/api__gantt_getscale.html ;
and get the amount of dates in the timeline area from the trace_x
property. You can return the indices dates as numbers in the following way:
gantt.config.scales = [
{
unit: "day", step: 1, format: function (date) {
const scale = gantt.getScale();
let index = scale.trace_x.findIndex(function (x) {
return +x === +date
});
return index + 1
}
}
]
Please check the example:

Thanks for reply,
And how to remove the offsets Before the first task? I had specify the startDate (gantt.config.start_date), but it seems not work
Hello,
You can specify the start date of the earliest task as gantt.config.start_date
to display a timeline area without empty
interval. You can get the start date of the earliest task from the getSubtaskDates
method:
https://docs.dhtmlx.com/gantt/api__gantt_getsubtaskdates.html ;
Please check the example of how it might be implemented:
