You should set bigger turbothreshold: http://api.highcharts.com/highcharts#plotOptions.series.turboThreshold

I’ve found another (and very simple) solution: You can set y-axis minRange property: yAxis: { … minRange : 0.1 } This makes Highcharts render yAxis min and max values when all data is 0. UPDATE: Highcharts 4.1.9 fix also needs: plotOptions: { line: { softThreshold: false } } updated js fiddle

Set allowDecimals: false, see API.

You can use Format Strings to help you format numbers and dates. x Decimal Places View the JSFiddle // point.percentage = 29.9345816 pointFormat: ‘{point.percentage:.0f}%’ // returns: `30%` – (rounds to nearest) pointFormat: ‘{point.percentage:.1f}%’ // returns: `29.9%` pointFormat: ‘{point.percentage:.2f}%’ // returns: `29.93%` pointFormat: ‘{point.percentage:.3f}%’ // returns: `29.935%` Thousands separator View the JSFiddle // point.percentage = 1029.9 … Read more

You’re looking for a plot line. See the documentation here: http://api.highcharts.com/highcharts#xAxis.plotLines. The basic format is: xAxis: { plotLines: [{ color: ‘#FF0000’, // Red width: 2, value: 5.5 // Position, you’ll have to translate this to the values on your x axis }] },

UPDATE use enableMouseTracking: Boolean Notice enableMouseTracking: Boolean was introduced after this question was asked Old Answer I just Disabled the heights point in the Tokyo series here is your code tooltip: { formatter: function() { if(this.series.name == ‘Tokyo’ && this.y == 26.5 ){ return false ; // to disable the tooltip at a point return … Read more

I guess setExtremes is the best way to go about it. Syntax should be: chart.yAxis[0].setExtremes(100,300); If one wants to just set minimum then chart.yAxis[0].setExtremes(100,null); worked for me.

You can also set the color individually for each point/bar if you change the data array to be configuration objects instead of numbers. data: [ {y: 34.4, color: ‘red’}, // this point is red 21.8, // default blue {y: 20.1, color: ‘#aaff99’}, // this will be greenish 20] // default blue Example on jsfiddle
