javascript - how to draw column with value=0 in highcharts -

i have chart , have line/bar when y-axis value zero.. (that because 0 right value , null absence of value).is possible? illustration in column-basic chart (http://www.highcharts.com/demo/column-basic). possible have value=0 tokio serie?.. draw it?

{ name: 'tokyo', data: [0, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4] }

i tried min property value less zero.. bar not visible... idea?

set minimum of yaxis below 0 , threshold null (that way columns extend padding y axis minimum) highcharts api: plotoptions.bar.threshold

example: http://jsfiddle.net/4w23mrod/

... yaxis: { min: -50, ... }, plotoptions: { bar: { threshold: null, ...

or

you can utilize minpointlength

example
