Hi everyone,<br><br>I have a frequency-wave number spectrum. In which the X axis is wave number(-4 to 4) and Y axis frequecy. The Y axis frequency values are explicitly defined.<br>My Y axis values are (/0.01, 0.0125, 0.016666667, 0.025, 0.05, 0.1/). So when we go from bottom to top, obviously the spacing between the tick marks increases. That is quite clear. In the plot, I want to make the spacing between each tick mark to be equal without changing the above tick mark values( i.e. extent the bottom and compress the top of plot) <br>
Is there any resources or method in NCL so that I can make the spacing between the tick marks equal (By using the above values) <br><br>Any help is highly appreciated..<br>sabeer<br><br><br>the plotting part is given below.<br>
