javascript - The bar chart from Sparklines won't load -

i have 2 charts sparklines: 1 pie , 1 bar. pie chart works fine bar chart dosen't load. on local web server, bar chart loads fine. i'm getting no errors @ all!

<div id="bar"><div id="chart">96,96,96,96,39,48,97,89,96,96,96,60,96,96,96,96,97,96,96,90,80,97,96,98,96,96,96,67,96,96,94,94,96,96,96,96,96,96,96,96</div></div>  $('div#bar > div#chart').sparkline('html', {     type: 'bar',     barcolor: 'white',     height: '30px',     borderwidth: 5,     bordercolor: '#f5f5f5',     tooltipformat: '{{value}}' }); 

you can find website charts here. data bar chart visible. idea why this?

success! double div#chart "error". when changed div#pchart pie chart , div#bchart bar chart, bar chart visible!
