i'm having lot of trouble trying create otherwise simple ggplot barchart of timedate variable on y-axis. plots fine using geom_point or geom_line , replace geom_bar , r either crashes or returns me blank, grey graph. my raw data character strings of format: day time 1/1/2015 2:30:14 2/1/2015 15:10:40 3/1/2015 8:50:05 and knowing ggplot2 can bit picky time , date classes, format variables posixct , date follows: library(ggplot2); library(scales) datetime <- data.frame(date = c("1/1/2015", "2/1/2015", "3/1/2015"), time = c("2:30:14", "15:10:40", "8:50:05")) datetime$date <- as.date(datetime$date, format="%m/%d/%y") datetime$time <- as.posixct(datetime$time, format="%h:%m:%s") then, creating simple scatter plot of data works fine: ggplot(datetime, aes(date, time)) + geom_point() + xlab("day") + ylab("time") + scale_y

i'm front-end developer trying write first back-end restful webapplication in php/mysql. what it's confusing me figure out how model works. in fe programming, wrote in angularjs, model service provides data webservice. model doesn't exists itself, services provide when calls controllers. in backend scenario have db stocks data, , there have retrieve data compose model. problem me is: data being updated continously each client talks backend, need keep model consistent db continuously changing. had use implementation similar frontend, model have being created when controllers commands interactions it, , solves problem me. but friend of mine (which skilled) told me approach wrong, , model have independent controllers. but, if db changes, how aware of , update model? i hope have being clear in backend mvc, model divided in 3 parts: domain, dao , service. domain representation of data, in case class attributes. dao class implements access database (or file

the actual value of assignment group can achieved referring assignment_group.parent.parent.not sure if can use glide records using visual studio 2010 connect web service , not able add required class gliderecord. is question reference fields in servicenow, or using visual studio servicenow? assignment group isn't derived field, it's reference field. asking how derived field off of sys_user_group table, dot-walking through assignment_group field? there isn't trick it. kind of script trying with? if it's client-side script, might running problem because can't dot-walk on client side; you'll need make glideajax (or, if performance not concern, gliderecord) query server. please more clear questions in future. cannot if can't decipher you're asking.
