[Solved]-Chart JS - set start of week for x axis time series-Chart.js

you can add isoweekday: true into time config

https://www.chartjs.org/docs/latest/axes/cartesian/time.html

you should modify axis settings to set max and min value (start-end date range probably). an example (nb! use your own required formats):

time: {
  unit: 'month',
  displayformats: {
     month: 'mm'
  },
  max: moment(data.end_date).format('mm'),
  min: monent(data.start_date).format('mm')
}

i realize i'm super late on this, but maybe you should try setting the distribution option to series. see the documentation here:

scale distribution

the distribution property controls the data distribution along the scale:

'linear': data are spread according to their time (distances can vary)
'series': data are spread at the same distance from each other

this should fix that weird formatting that you have where the spacing is all mucked up.
