Hi
I am still finding my feet with weewx and various templates and settings
but have an issue that I don't fully understand.
I have the latest Neowx template installed and everything seems to be
working. Week, Month and Year data and png charts all work fine but the
daily png charts are all blank.
Can anyone help?
I've attached the image generator section from my neowx skin.conf
Thanks

# This section lists all the images to be generated, what SQL types are to
# be included in them, along with many plotting options, such as color or
# font. There's a default for almost everything, if not specified below.
# Nevertheless, I have explicitly put in values, to make it easy to see
# and understand the options.
#
# Fonts can be anything accepted by the Python Imaging Library (PIL), which
# is currently truetype (.ttf), or PIL's own font format (.pil). See
# http://www.pythonware.com/library/pil/handbook/imagefont.htm for more
# details. Note that "font size" is only used with truetype (.ttf)
# fonts. For others, font size is determined by the bit-mapped size,
# usually encoded in the file name (e.g., courB010.pil). If a font cannot
# be found, then a default font will be used.
#
# Colors can be specified any of three ways:
# 1. Notation 0xBBGGRR;
# 2. Notation #RRGGBB; or
# 3. Using an English name, such as 'yellow', or 'blue'.
# So, 0xff0000, #0000ff, or 'blue' would all specify a pure blue color.

# The following option merits an explanation. The y-axis scale used for
# plotting can be controlled using option 'yscale'. It is a 3-way tuple,
# with values (ylow, yhigh, min_interval). If set to "None", a parameter is

# min_interval, what is set is the *minimum* y-axis tick interval.

## What follows is a list of subsections, each specifying a time span, such
## as a day, week, month, or year. There's nothing special about them or
## their names: it's just a convenient way to group plots with a time span
## in common. You could add a time span [[biweek_images]] and add the
## appropriate time length, aggregation strategy, etc., without changing
## any code.
##
## Within each time span, each sub-subsection is the name of a plot to be
## generated for that time span. The generated plot will be stored using
## that name, in whatever directory was specified by option 'HTML_ROOT'
## in weewx.conf.
##
## With one final nesting (four brackets!) is the sql type of each line to
## be included within that plot.
##
## Unless overridden, leaf nodes inherit options from their parent
# Default plot and aggregation. Can get overridden at any level.
