What is the algorithm for determining at what values the gridlines
appear for a log scale?
I tried the column chart in the playground using the following data:
var raw_data = [['Austria', 13,13,13,13,13,13],
['Bulgaria', 13,13,13,13,13,13],
['Denmark', 13,13,13,13,13,13],
['Greece', 6,13,13,13,13,584]];
var years = [2003, 2004, 2005, 2006, 2007, 2008];
And using the following settings:
{title:"Yearly Coffee Consumption by Country",
width:600, height:400,
hAxis: {title: "Year"},
vAxis:{logScale:true}}
The y-axis has the following gridlines:
1.6, 7.9, 39.8, 199.5, 1000
How are these values calculated?
