I'd say to make this kind of chart you're better off with a Gauge chart type where you can define separate bands like in your example.

Here's a working code:

 var gaugeChart = AmCharts.makeChart("chartdiv", { "type": "gauge", "axes": [{ "axisAlpha": 0, "tickAlpha": 0, "labelsEnabled": false, "startAngle": -150, "endAngle": 150, "bands": [{ "color": "#8da44c", "endValue": 50, "startValue": 0, "radius": "100%", "innerRadius": "95%", "balloonText": "Lime one" }, { "color": "#ce0004", "endValue": 30, "startValue": 0, "radius": "90%", "innerRadius": "85%", "balloonText": "Red one" }], "endValue": 100 }], "allLabels": [{ "text": "3,000", "align": "center", "y": "45%", "size": 35 }] });
