RDD graph without zero in Y axis.
- 
 I use the RDD graph to show the course of air pressure. 
 The rise in air pressure from 1020 to 1024 is only a 0.4% increase.
 On a y axis from 0 to 1024, that 0.4 % rise is barely noticeable.
 Is it possible to set RDD so that the Y axis runs from, say, 940 to 1040?
 Then an increase from, say, 1020 to 1024 would be more visible.

 --alt-autoscalelooks like it should do it.

 Re: RDD graph without zero in Y axis. The option --alt-autoscale give me unfortunately not what I need. 
 The first image is made without the option alt-autoscale.
 The second image is made with the option alt-autoscale.
 The only difference is the position of 0 in the Y-axis.
 Also the options alt-autoscale-min and alt-autoscale-max give me not what i need.
 I want to see on the Y-axis only the part between 940 and 1040.
