javascript - Issue with speedometer highcharts dynamically update guage range -


i have use case need modify guage range dynamically, when highcharts graph behaves weirdly , range goes out of bounds. please @ image belowspeedometer highchart

this happens after 7th iteration (value 0.007). can find code on jsfiddle @ http://jsfiddle.net/s6ltl/

my highcharts speedometer code (jsfiddle)

on each iteration, adding new plotband, not removing old ones:

chart.yaxis[0].removeplotband('red'); chart.yaxis[0].removeplotband('green');                 chart.yaxis[0].addplotband({     id: 'red',     from: newval - 0.005,     to: newval - 0.001,     color: '#df5353' // red }); chart.yaxis[0].addplotband({     id: 'green',     from: newval - 0.001,     to: newval + 0.005,     color: '#55bf3b' //green });
