database - Postgresql: direct replication on demand -


i have 2 postgresql databases (on different servers): lets call them stable , unstable. stable read purposes only. time time the stable updated current unstable.

i improve update process. dumping file , restoring not possible more due size of database. found many replication tools designed master-slave configuration, not do, slave (stable) updated on demand. tools seem more complicated problem want them solve.

ideally, simple tool interface pg_replicate source target result in target db being exact clone of source , data being transfered directly between 2 database servers (they connected local network) without creating large temporary files. database size 50 gb , growing, transfering sql inserts might not suffice.

so, there tool it? or close?

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
