How to draw a Multiple line chart using Jqplot?

Question

I have an array .I map the array data to plot the line chart using Jqplot. goog has two set of arrays.

goog={[arr1],[arr2]}

 

I map the data to the chart. 

for (var i = 0; i <= goog.length; i++) {
  plot1 = $.jqplot('chart1', [goog[i]], opts);    }

 

Here the Line chart is plotted for the last iteration only .The previous data are not plotted.
