javascript - x-area labels on hover -

-

i need add color xaxis labels when it's hover (like number 19 in picture). saw property later lost it.

need =)

and can set property (z-index) xaxis tick? cause color must white, , can't see color, when z-index less z-index chart's area.

for first question, use shared tooltip , point mouseover event change corresponding axis label:

   plotoptions: {         series: {             point: {                 events: {                     // on mouseover make xaxis label red                     mouseover: function(){                         var xaxis = this.series.chart.xaxis[0];                         $(xaxis.ticks[this.x].label.element).css('fill','red');                     },                     // on mouseout make gray again                     mouseout: function(){                         var xaxis = this.series.chart.xaxis[0];                         $(xaxis.ticks[this.x].label.element).css('fill','#606060');                     }                 }             }         }     },

example here.

for second question, z index svg little tricky. doesn't have true zindex can re-order rather it's dictated order in elements drawn. can't see matters, though, because labels drawn on top of chart area (or else wouldn't see them @ all).
