To anyone trying to add a left and right margin in a line chart in order to see the first and last dots (markers) entirely..

Go see http://dev.sencha.com/deploy/touch-c...examples/Line/ where the left pictures are cut!

Add this to your scripts:
Ext.override(Ext.chart.series.Series, {
getGutters: function() {
return [10, 10];
}
});

This code override the function that is used to calculate the chart gutters.
