title: How can I add a new, single point to a flot graph?
body: <p>I'm working with data set where observations are sequentially obtained. New data points need to be placed on a flot graph, one at a time. This is <strong>not</strong> a case where (unlike this <a href="https://stackoverflow.com/questions/7716631/add-or-highlight-a-single-points-on-a-jquery-flot-graph">previous question</a>) I can simply highlight an existing point; I need to add a new point.</p>
  
  <p>I know how to add a new point to the data series with .setData() and then redraw the graph with .draw(); however, when I have thousands of points, this slows things down tremendously, because I then have to redraw the graph completely several times a second.</p>
  
  <p>So - is there any way of simply adding a point to the plot? Or, if I can't use flot for this, does anyone have any suggestions for javascript libraries that would let me create a plot and add points sequentially?</p>
