java - Want to generate xy graph from 2 wave graph in J2EE (from MySQL DB) -

-

  1. i have create 2 columns in mysql database , insert data in that, each column contain 8-9 k data.
  2. then need plot data in chosen gui in 3 separate plots on 1 screen shown in attached image.
  3. time interval x-axis plotting individual graph 0.001.
  4. then need plot these 2 waveform data against each other xy graph shown in graph.

how achieve using j2ee because condition xy graph should appear within 2 or 3 second

regards, prashant

this answer pretty incomplete , pointer in general direction. solution consists of 3 steps:

  1. getting data database. there 2 options here:

    1. use simple sql using jdbc
    2. use jpa

    i assume have knowledge of that, if not there many tutorials on both topics.

  2. creating graph using java. suggest using http://www.jfree.org/jfreechart/index.html there alternatives. in scenario want render (temporary) image file. need play around find actual graph like.

  3. sending graph browser. sadly don't know how that.
