is their any way, by which i can get better visibility of the graph. i.e in the above graph the blue line is almost flattened on log y-axis.
if i zoom in as shown in below image i lose the data of green line.
is their any way i can get both data plotted completely and also with improved visibility

Considering your data is already in log scale and has huge difference between the plot, i suggest to please consider the following option-
Break the Y-axis to represent the graph using the file exchange submission

You need to
  1. Change ylim of axes
  2. turn the grid on
  3. turn minor grid on
  4. change the grid alpha
for example
grid on
grid minor
a = gca;
a.XAxis.MinorTickValues = [0:1:20];
a.GridAlpha = 0.7;
a.YLim = [10^-9 10^-7];
a.YTick = [10^-8];
similarly select the yminorticks you want by a.YAxis.MinorTickValues
