Highcharts - Change opacity of chart when tooltip is shown -

-

when tooltip shown, possible change opacity of data points in chart, exception of data point label shown?

i.e. in default column chart, when mouse moves on column, column highlighted bit. same event, i'd other column's opacity change 50%.

thanks

you can use point mouseover , mouseout events callback functions in case of chart. inside events can update color of specific points. http://api.highcharts.com/highcharts#plotoptions.area.point.events.mouseover http://api.highcharts.com/highcharts#plotoptions.area.point.events.mouseout

if use rgba colors, able set opacity. 

  point: {     events: {       mouseover: function() {         highcharts.each(this.series.data, function(p, i) {           p.update({             color: 'rgba(50,120,60,0.5)'           }, false)         });         this.update({           color: 'rgba(50,120,60,1)'         });       },       mouseout: function() {         highcharts.each(this.series.data, function(p, i) {           p.update({             color: 'rgba(50,120,60,1)'           }, false)         });         this.series.chart.redraw();       },     }   }

here can see example how can work: http://jsfiddle.net/4q10q8r1/

ok, know if have character '-' , want remove in places in string javascript, ... someword = someword.replace(/-/g, ''); but, when applying array of characters, s not working ... const badchars = ('\/:*?"<>|').split(''); let filename = title.replace(/ /g, '-').tolocalelowercase(); (let item = 0; item < badchars.length; item++) { // below not work global '/ /g' filename = filename.replace(/badchars[item]/g, ''); } any ideas? /badchars[item]/g looks badchars , literally, followed i , t , e , or m . if you're trying use character badchars[item] , you'll need use regexp constructor, , you'll need escape regex-specific characters. escaping regular expression has been well-covered . using that: filename = filename.replace(new regexp(regexp.quote(badchars[item]), 'g'), ''); but , don't want that. want character class: let filename = title.replac
