title: How to fix xtics label overlapping in gnuplot
body: <p>I'm using GNUPlot to draw the graph of five real-valued functions. I think it is easy to solve, but I am a beginner. 
  My x-axis has problems with its label. All the xtics numbers are overlapping, and I have no idea why.
  My .plt plots 3 files: an .eps, an pb .eps and a .png. It receives a .100 file, which is 6 columns of numbers. The first column represents values for t and the other five columns represent values for each function at respective t.</p>
  
  <p>My .plt file is:</p>
