title: how to set the range in the colorbar manually?
body: <p>I have a wide range of values and while plotting as a scatter(x,y,z), the colorbar showing the z axis shows a wide range of values, now I am not interested in the lower range values. Is there any method to change the range in color bar.
  I have the following part of my code to plot, I also intend to plot the log plot. For eg. I want to set the range in my log plot to 14 to the maximum value.</p>
  
  <p>I want some values not to be displayed at all. so that the color bar has a limited range, say from 14 to maximum. At present it is showing from 9 to maximum in the log plot.</p>
  
  <pre><code>scatter(x(1:end-1), y(1:end-1), 5, gnd);
  
  title('G plot (m^-^2)');
  
  colorbar('eastoutside');
  
  xlabel(' X-axis (microns)');
  
  ylabel('Y-axis (microns)');
  
  figure;
  
  log_g=log10(gnd);
  
  scatter(x(1:end-1), y(1:end-1), 5,log_g);
  
  colorbar('eastoutside');
  
  xlabel(' X-axis (microns)');
  
  ylabel('Y-axis (microns)');
  
  title('G Density, log plot (m^-^2)');
