Highcharts: Displaying zero values in logarithmic

问题:

I am working with logarithmic scale in the y-axis

I know that log(0) doesn't exist but I need to draw 0 values, and I need a log scale.

I read in other answers that changing the zero values to null solve the problem, but it is not working for me. See the example: http://jsfiddle.net/QEK3x/15/

Thank you in advance.

Although not perfect, the best I came up with was to set the zero point to 0.0001 and then set the y-axis min to 0.0001:

http://jsfiddle.net/6LHT8/

yAxis: {        
    min:0.0001,
    type: 'logarithmic'
},

series: [{
    data: [100,10,0.0001,0.1,0.01,0.1]
}]
