Flot Charts - handling multiple flots in a single

I have a display I implemented to a single chart and wan to extend the solution so that 3 charts will have same properties.

specifically:

I want to enable selection zooming + double click to reset the display
I want the legend of the series will be clickable so that the series will turn on/off with each click. I was successfully able to implement them based on previous posts

Here's a fiddle with 3 chart in a single page

Here's my original code (written in coffeescript):

colorArray = []
colorArray.push "rgba(180, 0, 75,    0.6)"
colorArray.push "rgba(0, 150, 100,   0.6)"
colorArray.push "rgba(0, 0, 255,     0.6)"
colorArray.push "rgba(140, 0, 255,   0.6)"
colorArray.push "rgba(90, 180, 20,   0.6)"
colorArray.push "rgba(255, 236, 0,   0.6)"
colorArray.push "rgba(234, 170, 21,  0.6)"
colorArray.push "rgba(95, 180, 190,  0.6)"
colorArray.push "rgba(214, 92, 63,   0.6)"
colorArray.push "rgba(218, 106, 234, 0.6)"
colorArray.push "rgba(213, 128, 155, 0.6)"

What would be the most efficient way to implement this (while trying to avoid code-duplication)?

Thanks!!

Create an array of your plots / charts

plotNames = ["bandwidth", "normalized_bw", "concurrent_flows"]

extend your togglePlot function to work with one plot

togglePlot: (plotName, seriesIdx) ->
    someData = this.plot[plotName].getData()
    someData[seriesIdx].points.show = not someData[seriesIdx].points.show
    this.plot[plotName].setData someData
    this.plot[plotName].draw()
    return

and use an jQuery each function to create the different plots and bind their events

jQuery.each plotNames, (index, name) ->
    if $("#"+name+"_chart").length
        Chart.plot[name] = $.plot($("#"+name+"_chart"), Chart.generateDataObjects(all_series, raw_data), Chart.generateChartOptions(name+"_legend"))

        $("#"+name+"_legend").on 'click', 'a.legendtoggle', (event) ->
            Chart.togglePlot(name, $(this).data('index'))
            return false

        $("#"+name+"_chart").bind "plotselected", (event, ranges) ->
            Chart.plot[name] = $.plot($("#"+name+"_chart"), Chart.plot[name].getData(), $.extend(true, {}, Chart.generateChartOptions(name+'_legend'),
              xaxis:
                min: ranges.xaxis.from
                max: ranges.xaxis.to
              yaxis:
                min: ranges.yaxis.from
                max: ranges.yaxis.to
            ))
            return

        $("#"+name+"_chart").bind "dblclick", (event, pos, item) ->
            Chart.plot[name] = $.plot($("#"+name+"_chart"), Chart.plot[name].getData(), $.extend(true, {}, Chart.generateChartOptions(name+'_legend'),
              xaxis:
                min: null
                max: null
              yaxis:
                min: null
                max: null
            ))
            return
