time_length = day_ago_to_now

Hi,

i try to create a chart with time-lenght=day_ago_to_now or hour_ago_to_now according to the documentation.
I do not succeed.

Your graphs.conf looks correct, but the error is not related to day_ago_to_now, it looks like day_ago_to_now is being skipped for some reason. 

Take a backup of graphs.conf, then try this as your only item in graphs.conf? 

[timetestchart]

    title = Time Test Chart

    show_button = true

    button_text = Time Test Chart

    gapsize = 300

    [[chart1]]

        title = Temperature

        time_length = day_ago_to_now

        time_ago = 1

        start_at_midnight = true

        #aggregate_type = max

        #aggregate_interval = 86400 # 1 day

        gapsize = 86400

        [[[outTemp]]]

            zIndex = 1

            name = Temperature

        [[[windchill]]]

        [[[heatindex]]]

        [[[dewpoint]]]

Ah, I see your gapsize is still in milliseconds. That tells me you haven't upgraded to the latest version of the skin, or you've skipped upgrading belchertown.py. 

Keep your graphs.conf the same, and upgrade all files to the latest version of all files. You'll notice in the development release notes the breaking change of gapsize is now in seconds (300) , not milliseconds (300000)

To avoid rewriting the graph.conf, I simply copied the old version (1.1.) into the Belchertown skin 1.2.
I will now rewrite to '300'. If it doesn't work, install it again.

My archive_interval is 60.
Had I to change the intervall to 300

Make the two match

I have completely deleted Belchertown and reinstalled ver. 1.2. Now the new features worked.
So it was a mistake of me to copy simply  files of the ver.1.1. into the ver. 1.2. . This mix did not work and led to some nonsensical requests in this group. I am sorry.
