I work on a number of personal IT projects (econometrics, robotics, etc) that all involve the display of data using charts in one form or another, either static or in real time.
The kind of charts I require are typically timeseries charts, XY plots, polar, but could extend to other types.
The requirement is for an application that can display such charts. What I need is a 'chart server' that simply displays charts, statically or in real-time, for any of the clients that are connected to it. Connection should be via a network socket.
Hence, the clients (typically console c/c++ apps) can focus on computations, they rely on the chart server to handle the display.
I do not intend to distribute this work, it is only for personal non-commerical use.
## Deliverables
The term application below refers to the 'chart server' explained in the description above.
**The application should:
**a) be written in java
b) use the jfeechart library for the charts. This library is well documented and simple to use (<[login to view URL]>), there is an important library of charts available which covers all needs so far
c) use a java socket to receive the data to be plotted
d) allow for real-time charts (update as soon as new info is recieved over the socket) and static charts
e) only one client to be connected at anyone time, but each client can have one or more charts being displayed
**Milestone:
**To get going, I need a version of the program that can handle time series (static and real-time) and xy plots (static and realtime) only. It should be able to recieve say 4000 data points from a c++ application.
**To be discussed:**
a) protocol for data transfer over the socket, e.g. what type of chart to create, the data, updating, etc
**Standard Terms:
**1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.
2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables):
a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment.
b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request.
3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement).
## Platform
Since the application will be running in Java and connection to the application is over a network socket, code should be pretty much platform independent.
I work on linux and windows 2000+ systems.
