I have faced a strange issue with the chart. I have defined grid lines for the chart. The code sample is given below
axes: [
type: 'Numeric',
title: 'fffd',
grid: true,
grid: {
odd: {
opacity: 1,
fill: '#dddddd',
stroke : '#ddd',
'stroke-width' : 1

Interestingly the first time i load the chart the grid lines comes correctly. But if i go to any other page in my app and come back to chart page it fails to draw the grid lines. Please find attached the screen shot.
