7.1 Introduction
Plotting data is one of the most essential parts of numerical computation
. In pre-processing, during computation, and in post-processing, the ability to plot data on different kinds of graphs is essential. Visualization of data in a convenient format allows for better understanding of the process. Visual clues generate a lot of information about the process that generated that particular data. You can easily look for errors and derive simple as well as complex interpretations. A good programming language must incorporate facilities to plot data easily. Plotting ...
