    Chart item=Temperature period=D refresh=3000
}

}

items

Number Temperature “Outside Temperature” { channel=“yahooweather:weather:berlin:temperature” }

things

yahooweather:weather:berlin [ location=638242 ]

Strategies {
everyMinute:“0 * * * * ?”

   default = everyChange

}

Items {

    Temperature : strategy = everyUpdate, everyMinute

}

What isn’t working? The Text or the Chart don’t show any value?

Are you sure that values are written into an .rrd file? (see here)

3

the chart is not working…i not touch services/rrd4j.cfg…i only create the rrd4j.persist file in the persistence folder

Strategies {
everyMinute:“0 * * * * ?”

default = everyChange
}

Items {

Temperature : strategy = everyUpdate, everyMinute

}

Did you check the .rrd files are existing?
Using the REST Api you can even check each entry into the rrd4j database.
