Hi
Could somebody show me how to correctly display a limit / constant value on
a plot
some time ago I alerted to a post about how to show a constant value in a
plot.
I have searched but I haven't found the right words to find that post again
but I copied it and use it in my skin.conf
[[[daywind]]]
# [[[[windSpeed]]]]
# [[[[windGust]]]]
# place limit line on graph
[[[[windMax]]]]
# data_type = function | this
# label = ' ' | does
# function_definition = 10.5 | not
# function_type = windSpeed | work
# color = red
data_type = 10.5
label = ' '
color = orange
width = 1
[[[[windSpeed]]]]
color = 0xb48242
[[[[windGust]]]]
color = 0x4242b4
I think it is a useful feature for me and it displays an orange line at 10.5
BTW the red line does not show on the plot and no errors appear in the log
(debug=1)
see here at oxleyweather.ddnsfree.com
Now I would like to display a constant value in another plot.
like this
[[[dayvolt]]]
yscale = 3.6, 4.2, 0.1
[[[[consBatteryVoltage]]]]
label = Transmitter battery
color = 0xb48242 # blue
# color = 0x4242b4 # red
# place limit line on graph
[[[[voltMin]]]]
data_type = function
label = ' '
function_definition = 3.7
function_type = consBatteryVoltage
color = red
# width = 1
But this doesn't show a red line, and there are no complaints in the log.
However if I use the wind example I get errors in the log .........
but not for the wind example ........only about the voltage limit
The Customization Guide under ImageGenerator doesn't give any details
Thanks
