Redundancy of graph in Neo4j -


i have created small graph in neo4j , respective nodes , relationships created. if run same code again, nodes , relationships again created instead of displaying message nodes , relationships exist similar oracle.

merge (a:person1 { name : 'roger', title : 'developer', age :28})   merge (b:person2 { name : 'britney', title : 'financier',age :32})   merge (c:person3 { name : 'christian', title : 'tester',age :24})  create (a)-[:husband{last_name:'white'}]->(b) return a,b,c;

so want clarify whether neo4j has duplication or nodes created many times

thanks in advance...

for reference, merge statements not creating new persons, create statement in end, see http://console.neo4j.org/r/qrzr6u saying upon re-execution

created 1 relationship set 1 property

you want merge on statements:

merge (a:person1 { name : 'roger', title : 'developer', age :28 }) merge (b:person2 { name : 'britney', title : 'financier', age :32 }) merge (c:person3 { name : 'christian', title : 'tester', age :24 }) merge (a)-[:husband { last_name:'white' }]->(b) return a,b,c;

see http://console.neo4j.org/r/vmfl2v example.

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 .
