rrdtool graph resolution changes when plotting yesterday

I am having problem with graph that plots yesterday. The resolution of Y axis looks like 1 hour. Graph is created with:

rrdtool graph /ram/temperature/sensors-yesterday.png \ --end 00:00 \ --rigid \ --width 638 --height 337 \ --border 0 \ --font AXIS:13:0 \ --color BACK#363636 \ --color CANVAS#363636 \ --color GRID#999999 \ --color MGRID#B5B5B5 \ --color FONT#CCCCCC \ --x-grid MINUTE:60:HOUR:1:MINUTE:360:0:%R \ --y-grid 1:1 \ DEF:Onetemp=ds_temperature.rrd:One:AVERAGE \

(code to shade the sunlight is not included)

When I plot graph for last 24 hours without --end 00:00 \

everything looks normal, resolution is 5 minutes (-24 hours graph)

Database is created with:

rrdtool create ds_temperature.rrd --step 300 \ DS:One:GAUGE:600:-60:60 \ RRA:AVERAGE:0.5:1:12 \ RRA:AVERAGE:0.5:1:288 \ RRA:AVERAGE:0.5:12:168 \ RRA:AVERAGE:0.5:12:720 \ RRA:AVERAGE:0.5:288:365

And sampled with data every 5 minutes.

The reason for the resolution change is that you do not have data at 5 minute resolution for more than 24h ... revisit your create statement. My suggestion:

rrdtool create ds_temperature.rrd  --step 300 \
DS:One:GAUGE:600:-60:60 \
RRA:AVERAGE:0.5:1:2880 \
RRA:AVERAGE:0.5:12:720 \
RRA:AVERAGE:0.5:288:365
