Make x axe shorter than hours_to_show

[miljbee]

How to have x_min greater than what's computed with hours_to_show ?
- or -
How to get data older than hours_to_show ?

That's because I am plotting a 'sliding delta' to observe energy consumption evolution over a year.
To get the delta, I map y values to y-ys[i-52] (52 weeks in one year)
So, for i<52 I have no data
and to get values for i> 52 I need more than 52 weeks of data
So, I have hours_to_show: 2y

The result is that I get a plot on the right half of x. How to have x starting only one year ago ?

Try adding range to your xaxis:

layout:
  xaxis:
    range: $ex [Date.now()-1*365*24*60*60*1000, Date.now()]

The initial data fetch will be done based on hours_to_show, but plotly will render the specified.
