After 1.3 update, no graph lines on homepage or day graphs

[TippyTurtle]

Does anyone have any suggestions? (Thanks in Advance.)

After updating to v1.3 Homepage and Day charts are missing their lines. Week, Month and Year are fine. I can not figure out why. I have played with a lot of settings like "lineWidth = 3", etc. The data is there when you mouse over...and in my sqlite DB. I can't figure it out.

My site is here:

The start of my graphs.conf looks like:

# Global Chart Defaults
# These are fallback options that charts will use if an option is not defined. 
aggregate_type = None
time_length = 90000 # Last 25 hours
type = line
lineWidth = 3
colors = "#7cb5ec, #b2df8a, #f7a35c, #8c6bb1, #dd3497, #e4d354, #268bd2, #f45b5b, #6a3d9a, #33a02c"
tooltip_date_format = "LLL"

[homepage]
    # Chart Timespan Defaults
    title = "Homepage"
    show_button = true
    button_text = "Homepage"
    time_length = today
    tooltip_date_format = "LLL"
    gapsize = 300 # This should be your archive_interval from weewx.conf

    [[chart1]]
        title = Temperature
        [[[outTemp]]]
            zIndex = 1
            name = Temperature

My weewx.conf looks like this for the skin:

I've solved my problem... archive_interval in weewx.conf must match gapsize in graphs.conf

My /etc/weewx/weewx.conf file has:
archive_interval = 600

...because I am using the very excellent weewx-sdr and switching between 433mhz and 915mhz for my sensors and need to stay on each frequency long enough to ensure readings.

Either during the 1.3 upgrade or from my own doing (most likely) my /etc/weewx/skins/Belchertown/graphs.conf had the default:
gapsize = 300 # This should be your archive_interval from weewx.conf

I've updated it to:
gapsize = 600 # This should be your archive_interval from weewx.conf

...and life is good again. :-)
