I attempted to use the highcharts method to attempt to set the color, essentially:
$.extend(true, chartObj.plotOptions,{
bar: {
dataLabels: {
enabled: true,
style:{
color: “white”
}
}
}
})
And it appears to set the CSS style on the text of the data label as white. Of course, the browser plows over this and implements the .sk-chart-standard .highcharts-data-labels tspan style in the skuidtheme.css applied on the parented div over the highcharts style.
