Subject: Re: Continuous Label Bar
Hi Dennis,
Thanks for the script. I tried it but this is not what I want.
Actually I want to plot topograpgy with many levels to make them look
continous.
For example see the topography plot.
http://en.wikipedia.org/wiki/Image:Oesterreich_topo.png
In this plot there are so many levels that they appear continous. I think
such a plot is possible only if a colormap is defined with few colors and
then interpolation is applied between the colors to create a continous band
of colors (like the labelbar in the above plot). I think there only five
colors (green,yellow,red, grey and white) are used in the above plot.
I hope you understand my question now.
Best Regards
Nadeem

Hi everybody,
I am trying to make a continuous label bar as shown in attached
file. I defined the
color map with colors used in the attached label bar.I tried different
options but couldn't succeed.
Any help or suggestion is highly appreciated
