List of Figures

Chapter 1. Prelude: understanding data with gnuplot

Figure 1.1. Number of finishers vs. time to complete (in minutes)

Figure 1.2. A DLA cluster of N=50,000 particles, drawn with gnuplot

Figure 1.3. Time required to grow a DLA cluster

Figure 1.4. Time required to grow a DLA cluster in a double-logarithmic plot, together with an approximate mathematical model

Chapter 2. Tutorial: essential gnuplot

Figure 2.1. Your first plot: plot sin(x)

Figure 2.2. An unsuitable default plot range: plot sin(x), x, x-(x**3)/6

Figure 2.3. Using explicit plot ranges: plot [][-2:2] sin(x), x, x-(x**3)/6

Figure 2.4. Plotting from a file: plot "prices" using 1:2, "prices" using 1:3

Figure 2.5. Introducing styles and the title keyword: plot "prices" using 1:2 title "PQR" with lines, "prices" using 1:3 title "XYZ" with linespoints

Figure 2.6. Any column can be used for either the x or y axis: plot "prices" using 2:3 with points.

Chapter 3. The heart of the matter: the plot command

Figure 3.1. Current athletic world-record running times as a function of the competition distance, for both men and women. The data is shown in listing 3.1.

Figure 3.2. Plotting a function for different values of a parameter: plot g(x,1), g(x,2), g(x,3) where g(x, s) = exp(-0.5*(x/s)**2)/s
