I'm not sure what the best way to set the increment for tick marks on an chart axis i.e. change the interval from a tick at every 5 numbers to each one.

For example, if I include "increment" in the config for the numeric axis in the example here:

http://try.sencha.com/touch/2.1.0/do....1/viewer.html

axes: [{
type: 'numeric',
position: 'left',
fields: ['data1'],
title: {
text: 'Sample Values',
fontSize: 15
},
grid: true,
minimum: 0,
increment:1
}....

...it doesn't seem to have an effect for the vertical numeric axis.

Do you have override the Ext.chart.axis.layout.Layout calculateMajorTicks method somehow?
