title: gnuplot: how to use a*(10^b) format on axis
body: <p>I am using really big numbers (milions) on my x-axis, so when I use</p>
  
  <pre><code>set format x %6.0f
  </code></pre>
  
  <p>I got big numbers like 25000000. That is quite nice, but takes much space, so there are only few labels and reader losts information.</p>
  
  <p>When I exclude setting format, I get something like 2e+07, what is quite unfriendly and unusual to reader according to my opinion.</p>
  
  <p>I would like format like 25*(10^6), so the number would be first and then multiplied by 10^n, or something very similiar to that. I think that would be the best solution, if the x-axis is long about 30000000 points or even more.</p>
  
  <p>However, reading manuals, e.g. "How do I change the format of the numbers ?" from <a href="http://web.archive.org/web/20100829220255/http://t16web.lanl.gov/Kawano/gnuplot/tics-e.html" rel="noreferrer">http://t16web.lanl.gov/Kawano/gnuplot/tics-e.html</a> did not help me much.</p>
  
  <p>Thank you in advance.</p>
