logging - Highcharts logarithmic computational algorithms -

when type "logarithmic" set xaxis,scale change "20k,40k,100k,200k,400k",can me explain highcharts logarithmic algorithms?

logarithmic axes used when have wide range of data values lots @ lower end, few values bigger.

imagine if trying plot following values:

1 2 3 10 1000 10000 

if y axis values spaced evenly, first few datapoints same, tiny compared max.

if give more space smaller values, , less large values, can show more detail @ smaller end of scale.

it's easier show in action. jsfiddle shows same data plotted , logarithmically : http://jsfiddle.net/qsstj/
