One can plot piecewise-defined functions in gnuplot with the ternary condition operator? For instance, one can manually define the absolute value function by:.
For piecewise functions, you will likely want many samples, so that discontinuities appear as vertical lines, and corners appear sharp, so:. Using instead of avoids artifacts of having a sample point appear directly on a discontinuity, which can introduce "stair steps. Better yet, switch to parametric mode, map a common t interval  to your individual t ranges, and then:.
This is very useful for complicated graphs. Alternatively, other file extensions, such as. Also see a github repository compatible with pathogen's auto filetype detection features. The file name should be changed to something more descriptive, though this is not strictly necessary. Beware that with horizontal writing, the y-axis labels will likely take up more space horizontally than the x-axis labels take vertically , and thus a nominally square graph will have an actually graphing area which is slightly taller than it is wide.
This can be useful to add annotations which would be otherwise hard to produce in gnuplot, or one may incorporate the plot as one component of a larger or more complex figure.
There are a number of design considerations in graphs, considered as information graphics. A good resource are the works and writings of information graphic designers, such as the highly regarded works of Edward Tufte: his The Visual Display of Quantitative Information is most relevant for graphs, but his and others other work can be insightful and inspiring. The first consideration is what to graph, and whether a graph is the best way to convey certain information: graphs can be unexpectedly useful, or conversely, a graph may not be the best way to convey information.
Further, how a graph is connected an integrated with other material is a question — is it referred to? Described and discussed? From Wikibooks, open books for an open world.

It primarily goes over the basics of how to plot and fit simple things with Gnuplot. Most of the things here should work well with any reasonably recent version of Gnuplot, but no promises. This tutorial supposes the existance of a sparse data file with a rough decaying exponential. The one I used can be found here. If you'd like to see the plots, click on any of the plot or replot commands. Tutorial plot 'exp. In other words, it assumes you mean this: plot 'exp.
This section details the functionalities provided by the Aggregator class to an ns-3 simulation. An Aggregator object is supposed to be hooked to one or more trace sources in order to receive input. Aggregators are the end point of the data collected by the network of Probes and Collectors during the simulation. Typically, an aggregator is connected to one or more Collectors. To create a GnuplotAggregator in dynamic memory with smart pointers, one just needs to call the ns-3 method CreateObject. The first argument for the constructor, fileNameWithoutExtension, is the name of the gnuplot related files to write with no extension.
Wendel Ricardo flag Denunciar. Hotkeys bind command are disabled if keypress is one of the end conditions. Zooming is disabled if button3 is one of the end conditions. See mouse variables p. Note: Since pause communicates with the operating system rather than the graphics, it may behave differ- ently with different device drivers depending upon how text and graphics are mixed.
