[Gnuplot-info] How to combine a linear range and log-scale range in the same X-axis?

[Tomás N. <lla...@ho...>]

Hello all.

I have not found the way to solve the following problem:

I want to plot a set of data in only one plot.

The problem is that some points of the data should be better plotted in a 
linear scale (lets say 0 to 100,000) but there are other data points that, 
exceding the value 100,000, would be better plotted in a logarithmic scale, 
as they goes in the range 100,000 to 500,000,000.

Let's say the data is:

     X       Y
        0   100
    10000    80
    20000    75
    30000    60
    40000    55
    50000    50
    60000    48
    70000    45
    80000    43
    90000    41
   100000    40
   500000    35
  1000000    30
  5000000    25
 10000000    20
 50000000    15
100000000    10
500000000     8

(in fact there are much more data points in the 0-100,000 interval)

Is there a way to plot all these points in the same plot in only one X-axis 
showing two different ranges in that axis:
linear: 0-100,000
logarithmic: 100,000 - 1,000,000,000 ?

The axis would be read, for example, as:

|-----|-----|-----|-----|-----|-----|-----|-----|-----|
0    2E4   4E4   6E4   8E4   1E5   1E6   1E7   1E8   1E9
Thanks.
