line gaps

i am getting a sequence of points plotted rather than a line showing.

line_type = solid
line_gap_fraction = 0.3

the points are 20 mins apart. 20min/24hrs = 0.013 so i expect the points to be joined.

i have tried line_gap_fraction 0.9 and - just to be thorough - 1.0 and (being silly) 10.0 - with no change.

any ideas how to ‘join the dots’?

google is my friend but he didn’t help this time.

cheers

Things to check:

You didn't show the relevant part of skin.conf, but are you trying to do a bar plot? Option line_gap_fraction does not work for a bar plot. Try a line plot. See Issue #818.

What's in the database for this time period?

As always, the log.

the two problematics values are river_level2 and river_temp2.

the former is not showing the lack of line well presently but the latter is showing it quite clearly.

i have been using markers to visually enhance in lieu of missing lines, but they are turned off for this exercise

skin.conf extracts:

[[[plots/dayriverlevel]]]

yscale = 20, 90, 10

y_label_format = %0.0f

line_gap_fraction = 0.3

[[[[riverLevel]]]]

label = River Level by pressure

[[[[river_level2]]]]

label = sonar

#marker_size = 1

#marker_type = box

[[[plots/daytempcombined]]]

line_gap_fraction = 0.3

[[[[outTemp]]]]

label = Temperature Air

[[[[dewpoint]]]]

label = DewPt

[[[[river_temp2]]]]

label = River

#marker_size = 1

#marker_type = box

resulting graphs with isolated dots instead of joined lines on river_level2 and river_temp2 within their shared respective graphs:

archive interval is 5 mins.

river_level2 and river_temp2 data arrive (independently) each 20 mins i.e. four archive intervals.

the others above arrive in seconds, so well within one archive interval.

i am using box markers to visually enhance the points on unexpectdly unjoined lines

looking in the database, values for these variables in last 12 hours:

sqlite> select datetime(datetime,'unixepoch','localtime'),outTemp,dewpoint,river_temp2,riverLevel,river_level2 from archive where datetime(datetime,'unixepoch','localtime') > datetime('now','-12 hours','localtime');

hopefully it’s just me doing something dumb.

Things to check:

You didn't show the relevant part of skin.conf, but are you trying to do a bar plot? Option line_gap_fraction does not work for a bar plot. Try a line plot. See Issue #818.

What's in the database for this time period?

As always, the log.

i am getting a sequence of points plotted rather than a line showing.
line_type = solid
line_gap_fraction = 0.3
the points are 20 mins apart. 20min/24hrs = 0.013 so i expect the points to be joined.
i have tried line_gap_fraction 0.9 and - just to be thorough - 1.0 and (being silly) 10.0 - with no change.
any ideas how to ‘join the dots’?
google is my friend but he didn’t help this time.

You're not doing something dumb. None values always mark line breaks.

this means line_gap_fraction relates only to interval gaps of whole records, not of column value gaps within successive records.

hmm, inserting interpolated values to cover interval gaps in a column can only be done to past records - nope, i don’t want to go there...

well, now i know - learn to love the ‘mark’ not the ‘line'.

thanks

Speaking of dumb, in retrospect, this seems like a dumb choice. It should be at least optional.

The code was written about 10 years ago. I simply cannot remember why I chose to always honor None values, despite any value of line_gap_fraction.

A PR would be welcome, should you wish to write one.

fair request, but i don’t GitHub, so some code follows.

my old RPi test box is now my production LoRaWAN box, so i worked using my production weewx box, so testing is pretty minimal (seems to work on my two graphs)

see weeplot/utilities.py:520 on weewx 5.8.0:

line = []
last_x = None
for xy in zip(x, y):
#GE start new
# If the y coordinate is None, ignore it
if xy[1] is None:
continue
#GE end new
dx = xy[0] - last_x if last_x is not None else 0
last_x = xy[0]
#GE start original
#GE # If the y coordinate is None or dx > maxdx, that marks a break
#GE if xy[1] is None or (maxdx is not None and dx > maxdx):
#GE end original
#GE start new
# If dx > maxdx, that marks a break
if (maxdx is not None and dx > maxdx):
#GE end new
# If the length of the line is non-zero, yield it
if len(line):
yield line
line = [] if xy[1] is None else [xy]
else:
line.append(xy)
if len(line):
yield line

I just tried to implement my LoRa Temp/hum sensors in weewx via MQTT. One problem is that these sensor often use a time period of 20min as Graham Eddy wrote.

Will this code snippet from him find it's way in the next release to get a smoother graph in weewx!? Would be great.
