How to show a single marker in the jqplot graph

Hi im using jqplot graph. I need to hide the Circular points that are currently displayed on the plot chart for each value in the array except the last point.

I use the following code to display the chart. I used "show marker : false" option, but it hides all circular in the graph. Please help me how to show only one circular point in the graph.

<div id="chart2"></div>

var line2 = [['2012-10-02', 20],['2012-10-03', 45],['2012-10-04', 35],['2012-10-05', 32],['2012-10-06', 30],['2012-10-07', 25]];
var plot1 = $.jqplot('chart2', [line2], {

seriesDefaults: {
    showMarker: false
},

axes:{
    xaxis:{
      renderer:$.jqplot.DateAxisRenderer,
      labelRenderer: $.jqplot.CanvasAxisLabelRenderer,
      tickRenderer: $.jqplot.CanvasAxisTickRenderer,
      tickOptions: {
          angle: -90,
          formatString: '%m/%d/%Y'
      },
    }
  },
yaxis: {
     labelRenderer: $.jqplot.CanvasAxisLabelRenderer
},
highlighter: {
    show: true
  },

  cursor: {
    show: false
  }
});

I want to achieve the below screen as my output. please help me how this could be done. Any help will be appreciated.

There is no direct way of doing this using jqplot. but you can achieve this by making the following changes: jsFiddle link

$(document).ready(function(){
  var line2 = [['2012-10-02', 20],['2012-10-03', 45],['2012-10-04', 35],['2012-10-05', 32],['2012-10-06', 30],['2012-10-07', 25]];
    var line3 = [['2012-10-07', 25]]; 
var plot1 = $.jqplot('chart1', [line2, line3], {

    series: [
        {
            showMarker: false
         },
        {
            showMarker: true
         }
],

axes:{
    xaxis:{
      renderer:$.jqplot.CategoryAxisRenderer,
      labelRenderer: $.jqplot.CanvasAxisLabelRenderer,
      tickRenderer: $.jqplot.CanvasAxisTickRenderer,
      tickOptions: {
          angle: -90,
          formatString: '%m/%d/%Y'
      },
    }
  },
yaxis: {
     labelRenderer: $.jqplot.CanvasAxisLabelRenderer
},
highlighter: {
    show: true
  },

  cursor: {
    show: false
  }
