Netplot is a tool for plotting values on a GUI from platforms with no GUI interface over a network connection. It was designed as tool that is useful to incorporate into programs (particularly aimed at embedded Linux systems) when attempting to visualise data when debugging or attmpting to visualise internal state.
Java netplot gui and client code Run the command 'ant clean build jar' command (in the same path as the build.xml file, to compile the Java code and build the output jar files. Once the build is complete the netplot_gui.jar and netplot_client_demo.jar files should appear alongside the build.xml file. This requires that Java (SDK) and ant is installed.
Python netplot client. The python_client folder contains the python client. This file may be executed directly ('python netplot_client_demo.py' command) to display the demo graphs. This requires that Python is installed.
C client code This resides in the c_client folder. From this folder run the 'codeblocks netplot_client.cbp' and select the Build option from the Build menu. This requires that codeblocks is codeblocks IDE installed.
-
Run 'java -jar netplot_gui.jar' on the computer with a GUI interface and a java JVM installed. This will display an empty window and start a number of TCP servers on separate TCP sockets. Each TCP socket can be used to display a single plot on the GUI interface. When a netplot client connects to the server it can display plots on the GUI.
-
Run the 'java -jar netplot_client_demo.jar' command on the same computer (it can be executed on a different computer if the --host command line argument is used) to display the demo plots.
-
To run the python netplot client demo code start the netplot_gui as detailed above then run 'python netplot_client_demo.py' from the python_client folder.
-
To run the C python netplot client demo code, build the code as detailed previously the run the netplot_client program from the c_client/bin/Debug folder.
The netplot client in the above example is Java based. A python and C implementation of the netplot clients (and demo program code) are included for adding netplot capabilities into software that use these languages.
You can now take the client code (which is fairly small) and build it into your programs in order to add netplot support to them.
