jquery - display alt image in IE, because it doesnt display sparkline -

we use peity display sparkline graphs.

the code have js is: ( hope correct , works fien in chrome , ff )

$(function(){       $(".line").peity("line",{         colour: "#c6d9fd",         strokecolour:"#4d89f9",         strokewidth:1,         width:200,         height:44       } 

); });

the code display sparkline is:

<span class="line">1,23,4,7,5,9,10</span> 

within ie, not display sparkline, , rather have show:

1,23,4,7,5,9,10

i display else, perhaps small png image etc. dooable. like:

if ie display blah blah blah

you can write if ($.browser.msie && $.browser.version < 9)
