Highcharts gauge not showing colour as expected - highcharts

Question

I have 3 stops at 0.4, 0.6 and 0.8 (red, green, blue). The maximum is 100 (for percent)
If I set the data as 50, I expect it to be green but it seems to be a mix of the green and red. It's only when I get to 60 that it's bright green that I expect.
Anyway to remove the gradient?

Instead of using stops property, you can change the color of the point programmatically, based on some condition:
events: {
render: function() {
var point = this.series[0].points[0];
if (point.y < 40) {
point.graphic.attr({
fill: '#ff0000'
})
} else if (point.y < 60) {
point.graphic.attr({
fill: '#00ff00'
})
} else {
point.graphic.attr({
fill: '#0000ff'
})
}
}
}
