How to Use Xgraph in Ns2
Are you guys looking for technical explanations based different approaches in the process of how to use Xgraph in Ns2 and then no doubt you are the right place. Shall we start this article with the short note about Xgraph in the following? Let’s go ahead…
What is Xgraph?
The Xgraph includes the ability for the specification of color plotting and multi-color plots are functional through the line of thickness. It is capable for the utilization of multi column file for the functions of abscissa and ordinate axis. In addition, it is supportive for the automatic resizing process of windows.
What is Ns2?
Ns2 is considered as the provision of both the type of simulation such as animation based and text based. The implementation of object oriented language is providing the two outputs such as.
- .tr file
- It is denoted as the trace file and it is the output of text based simulation
- .nam file
- It is the provision of animation based simulation
The simulation in Ns2 is functioning to learn the process of Xgraph tools are including the input of trace files and that is capable to generate the line graphs. In addition, it is permitting the users to analyze the network performance over the metrics such as bandwidth consumption, delay, throughput and etc. The process of analysis takes place through the created scripts based on network performance C++ and the main trace file is provided with the input of given numeric results with the terms of some performance metrics.
Interactive and Batch Usage
- Batch mode
- When the windowing interface is not available, the Xgraph is used when it is not desired as the view data as the on screen process. For instance, this process is similar to the remote working process and automatic report generating process overnight and the X-Graph is deployed as the mode with some simple options for the command line such as
- -pptx
- -odp
- -eps
- -ps
- It is capable to display the attempt as the open source of onscreen through sending the graph directly for the specification of file format
- Interactive
- The default mode is considered as the interactive process. While the situation is invoked, the graph window is appeared through control panel of buttons and the operations based on button are listed in the following. The users can select the area based graph to zoom through dragging the rubber band line around the region of graph as the interactive process. Additionally, the users are capable to zoom in and out the pan using some control panel buttons. It is returning to the display the original scale and that is to rezoom into various region
- The user have to click the graph to display the coordination of points for the terminal window and the users can click the one point and then another to view the distance and difference among the two points have been printed
Command Line Options
The programs based on Xgraph includes various options to present the graph data and the list of opinions are viewed through pressing the help button and by invoking the Xgraph along with the “-help” command line option and the options are utilized for the alteration of default settings.
The various aspects are altered through the interactive process of graph control panel and that the command line options are functional with some convenience. It is permitting the graph that line up the required mode of pressing various buttons. On the other hand, the non-interactive or the script driven usage with that command line options are required. The process is permitting the display modes which have to be set and the hardcopies are generated without the requirements of interactive displays through some buttons. In addition to that our research professionals have enlisted the options based on command line with its specifications in the following.
- -ng
- It stipulates no grid and turns grid off
- -g
- It is the implementation of geometric equality of scale on both axis
- -y_range
- Specify rigid Y-axis range and must be followed by two values
- If specified before files and used as the soft outer limits which will be stretched if data values exceed given range
- When it is specified after files, it is used as rigid range which will restrict graph boundaries even if data exceeds given range
- -x_range
- It is the specification of X-axis range and it have to be followed over the two values
- If specified before files and used as the soft outer limits which will be stretched if data values exceed given range
- When it is specified after files, it is used as rigid range and that will restrict graph boundaries even if data exceeds given range
- -text
- Put extra text on graphs
- -titles
- Toggle titles on graph axis
- -help
- It is used to print the list of options
- -pptx
- It is the non-interactive power point document format (PPTX) output
- -odp
- Open office document format is abbreviated as ODP and it is the non-interactive ODP output
- It is useful for the batch script driven jobs
- Portable document format is abbreviated as PDF and it is the non-interactive PDF output
- It is beneficial for the batch script driven jobs
- -pl
- It is deployed to plot the points using lines. It is the depiction of where the data samples are on the curves with tick marks
- -columns
- It is used to highlight the columns on command line
- -color
- It is the specification of color and the data from a file has to be drawn in
Changing Graph Placement on Page
The users are capable to specify the size and location graph through the printed page through the specification of all the boundary positions such as right, left, lower and upper. In addition, it is beneficial for the process of shrink graph to fit the textual explanation for all the sides. The boundaries are independently specified through the command line within the data file through the utilization of following mentioned command line and in file.
- In file
- right_boundary = <position>
- left_boundary = <position>
- lower_boundary = <position>
- upper_boundary = <position>
- On command line
- -right_boundary <position>
- -left_boundary <position>
- -lower_boundary <position>
- -upper_boundary <position>
It is about the <position> which is in inches and that to from the top of the 8.5 inch high page. In addition, to that we have includes some default positions such as.
- right_boundary = 10.5
- left_boundary = 2.75
- lower_boundary = 7.0
- upper_boundary = 0.5
Specifying Number of Division on Axes and Grids
The user can specify the number of divisions in all the axis through two command line options such as -ngrids_x and -ngrids_y. For instance, -ngrids_x 8 is leads to attempt for the axis division into the 8 tick marks and it includes some default values such as ngrids_x + 7 and ngrids_x + 5.
Specifying Columns to Plot
It is deployed to specify the column numbers based on command line and the columns option. In addition, we have highlighted with an example.
- xgraph -columns 1 5 dat
- It describes that plot column 5 is functioning against column 1 from the test.dat
Now, it’s time to move to the research topics based on Xgraph in Ns2. Our research professionals in this field have enlisted the significant list of research topics.
