As with chart_fill_colors, chart_line_colors is an option setting that is applied to a chart, not individual 'lines'. You have chart_line_colors set under the 'line' [[[[electricityLinky]]]] so it is effectively ignored ( chart_line_colors has no meaning when used under a 'line'). If you want to specify a list of colours (be it fill colours or line colours) you need to set chart_xxxxx_colors under the plot definition (in this case [[[daylinky1]]]), if you want to specify individual fill colours or line colours then you need to set xxxx_color under each 'line' definition (in this case [[[[electrictyLinky]]]]). You can mix and match if you want, eg specify chart_fill_colors for a plot and specify line_color for each 'line' in the plot (or vice versa), you just need to make sure the option settings are put in the correct place/level.
