Show legends horizontal in line charts are not working

[niewie]

I am trying to display my legends on a line chart horizontally, and
tried to use the numberRows : 1 options but it simply won't work. It
works on some of the other chart types. Can anybody try to make
legends show horizontal on specifically a line chart and let me know
if it works for you?
Thanks!

I have it setup like this for one of my line charts (the chart has 3 series, so I have 3 columns in the legend):

legend: {

// Enable rows and columns in the legend

renderer: $.jqplot.EnhancedLegendRenderer,

show: true,

// place label on top of graph

location: 'n',

// place label outsid the graph plot and add space above the graph for no overlay

placement: 'outsideGrid',

// set the labels for the legend to the labels array

labels: labels,

// set the number of rows and columns for the legend

marginTop: 0,

rendererOptions: {

numberRows: 1,

numberColumns: 3,

seriesToggle: false,

disableIEFading: true

}

},

Do not forget to include EnhancedLegendRenderer : 

legend: {

  ...

  renderer: $.jqplot.EnhancedLegendRenderer,

  rendererOptions: {...}

}
