image genarator/skin.config

[bwal...@gmail.com]

Hi

 i have some problems with image genaration.

First i found out, if no font is specified or (font is not found), change of of fontsize has  no effekt.

 

im also not able to change line width:

sektion in skin config:

    # Default colors for the plot lines. These can be overridden for

    # individual lines using option 'color'

    chart_line_width = 3, 1, 1

    chart_line_colors = "#4282b4", "#b44242" , "#42b442"

 

"chart_line_colors" as hex should be in quotes, unlike in the decription of imagegenerator.

 

an an other wired thing:

uv plot weekly  could be more than 16?
not shure whats going on there...

 by the way no errors in logfile.

Yes, this is a little subtle.

The option `width` is overriding option `chart_line_widths`. Comment it out, and `chart_line_widths` will work.

    chart_line_width = 20, 1, 1

    # Default plot parameters
    plot_type = line
    aggregate_type = none
    # width = 1   # <- comment this line out
    time_length = 86400 # 24 hours

Indeed some colours need to be enclosed in single or double quotes, not so much because they contain hex characters, but rather because they contain the # character. In a config file the # character indicates a comment and any text on the same line following the # is ignored. I see the config extracts in the manuals don't have quotes but actual config files do and that could be confusing. I will update the manuals.

The source of your UV week plot problems is that you are asking the plot generator to plot the sum of the UV values in each hour. If you have the typical five minute archive period there will be 12 UV readings being summed to make up each point on the plot. To fix it remove the below highlighted line and you will instead see the average UV reading each hour:

        [[[weekuv]]]
            yscale = 0, 16, 1
            [[[[UV]]]]
                aggregate_type = sum
                aggregate_interval = 3600
                label = Ultraviolette Strahlung
