[solved]Charts problem - all seems ok but are blank

please can someone to figure out why after a raspberry migration from another device, I am not able to display charts anymore ?

I install the persistence via PaperUI
here in /etc/openhab2/persistence folder

Strategies {
everyMinute:"0 * * * * ?"
everyHour : "0 0 * * * ?"
everyDay  : "0 0 0 * * ?"
default = everyChange

Items {

	Est_Temperatura : strategy = everyMinute, restoreOnStartup
Est_Umidita : strategy = everyMinute, restoreOnStartup
Est_Pressione : strategy = everyMinute, restoreOnStartup
Temperatura_Int_Soggiorno : strategy = everyMinute, restoreOnStartup
Umidita_Int_Soggiorno : strategy = everyMinute, restoreOnStartup
Luminosita_Int_Soggiorno : strategy = everyMinute, restoreOnStartup


a little part of the items files

Number   Est_Temperatura   		"Temperatura [%.1f °C]"  				<temperature>  		(Meteo) 					{weather="locationId=myhome, type=temperature, property=current"}
Number   Est_Umidita      		"UmiditĂ  [%d %%]"      					<water>  			(Meteo)  					{weather="locationId=myhome, type=atmosphere, property=humidity"}
Number   Est_Pressione      	"Pressione [%.0f mbar]"	 				<temperature>   	(Meteo)						{weather="locationId=myhome, type=athmosphere, property=pressure"}

a litthe part of the sitemap

Text item=Est_Temperatura valuecolor=[Meteo_LastUpdate=="Uninitialized"="lightgray",Est_Temperatura>40="red",>30="orange",>15="green",>5="teal",<=0="blue"]{
            Frame {
                Switch item=Meteo_Periodo_gTemperatura mappings=[0="Hour", 1="Day", 2="Week", 3="Month", 4="Year"]
				Chart item=Est_Temperatura period=h refresh=6000 visibility=[Meteo_Periodo_gTemperatura==0, Meteo_Periodo_gTemperatura=="Uninitialized"]
				Chart item=Est_Temperatura period=D refresh=30000 visibility=[Meteo_Periodo_gTemperatura==1]
				Chart item=Est_Temperatura period=W refresh=30000 visibility=[Meteo_Periodo_gTemperatura==2]
				Chart item=Est_Temperatura period=M refresh=30000 visibility=[Meteo_Periodo_gTemperatura==3]
				Chart item=Est_Temperatura period=Y refresh=30000 visibility=[Meteo_Periodo_gTemperatura==4]

Persistence/rrd4j Folder is populated with .rrd files…all semms OK but charts are Blank!!!

Before the CPU changes, charts was working…Can some one explain me what I missing??


I didn’t have any LOG line about these problem…thats why I didn’t copy any log line.

Maybe I need to enter in debug mode to extend log info ???

The problem Fix by itself after update from OH2.1 to OH2.2 … Now charts works properly without any change…
