ScatterPlotDemo1.java

[mdjy9953]

Hi experts,

Any idea how I may adjust the example of "ScatterPlotDemo1.java", in the jfreechart demo, so that the program repeatedly re-read data from a file and then displays the updated data on the chart? In other words, I want to build a "dynamic ScatterPlotDemo".

Another issue, is it possible to "move" a data item from one series to another? if possible, any clue how?

There are so many formats that could be used for data in a file. So JFreeChart mostly avoids getting involved in that - you need to write your own code that extracts the data from the file, and updates the JFreeChart dataset accordingly.

Another issue, is it possible to "move" a data item from one series to another? if possible, any clue how?

It depends on the dataset implementation you are using. But in principle, just delete the item from one series, and add it to another.
