将新数据点添加到已保存的图形中

Question

I have a question about plotting graphs on the web. I want to graph large amount of history data on a graph. But the problem is that I do not want it to start over plotting all the data from the beginning of time every time the we page gets opened. in other words I want it to save the plot of history data and every time the web page gets open just add the new point to the graph for example assume I have this array

History=[(0,1),(2,10),(3,100)]

and I have its graph too before and my new point:

NewPoint=(4,1000)

how can I just add the (4,1000) to the graph without having to plott all the data again? I am using Phplot now. Do you thing it is possible in phplot or API?

我不熟悉phplot，但是highcharts （鼓励熟悉javascript / jQuery / json）支持在某些图表上单击添加点，并且在其他图表上具有自动刷新功能，可以重新加载数据并重绘图形每“ x”秒。
