Dygraphs change series name dynamically? -

-

i have dygraphs chart has 115 or series plotted on it. works great. however, i'm trying figure out how retrieve series name of highlighted series, , how format number.

example on dygraph fiddle page (though, use big php string data, won't shown). http://jsfiddle.net/em2mg/861/

i end highlighted label of "year: 1955 y73 portfolio: $1,000,000". want able retrieve 73 number, , edit says. can't find in dygraph js file specific label formatter series number ,or method retrieve it. don't want have label every series manually.

ideas? great charting software.

gr = new dygraph( // containing div document.getelementbyid("graphdiv2"), // csv or path csv file. <?php echo $chartdatastring2; ?>, {     title: 'spending level',     ylabel: 'spending ($)',     xlabel: 'year',     labelsdivstyles: { 'textalign': 'right' },     digitsafterdecimal: 0,     yaxislabelwidth: 100,     axes: {         y: {                   labelskmb: false,                 maxnumberwidth: 11,                 valueformatter: function numberwithcommas(x) {                     return 'spending: $' + x.tostring().replace(/\b(?=(\d{3})+(?!\d))/g, ",");                 },                 axislabelformatter: function numberwithcommas(x) {                     return '$' + x.tostring().replace(/\b(?=(\d{3})+(?!\d))/g, ",");                 }         },         x: {             valueformatter: function numberwithcommas(x) {                     return 'year: ' + x;                 },         },     },     showlabelsonhighlight: true,     highlightcirclesize: 3,     strokewidth: 1.5,     strokeborderwidth: 0,  highlightseriesbackgroundalpha: 1.0,     highlightseriesopts: {       strokewidth: 4,       strokeborderwidth: 2,       highlightcirclesize: 5,     }, } );

the built-in dygraphs legend charts, @ point outgrow it. sounds you've reached point. i'd suggest hiding built-in legend , implementing own using highlightcallback , unhighlightcallback. can access series names via g.getlabels().
