-This example is here to test new plot functions. This test is based on file
-test_dispersion:
-Example:  Example of supercontinuum generation in anomalous dispersion regime
-at a central wavelength of 835 nm in a 15 centimeter long fiber.
-Comparision of results obtained with two dispersion input:
-1. dispersion calculated from Taylor expansion
-2. dispersion calculated from effective refractive indicies
-
-The python code based on MATLAB code published in
-'Supercontinuum Generation in Optical Fibers'
-by J. M. Dudley and J. R. Taylor, available at http://scgbook.info/.
+This example presents potential of new plot functions.
+Especially:
+    -different scales(linear and logarithmic)
+    -different x arguments(delay, frequency, wavelength)
+    -color map as argument of plot function
+    -slice plot for chosen z(propagation) distances
+    or z=0 and z=end if no specific z were chosen.
+Data used in this example are taken from test_Dudley.py file from examples.
