hi Suvarna,
Please use 'draw string x y string' command to draw x,y labels
and title to have a full grep on their size, color, style etc. Please
find an attached file cbar1.gs (a little modification of the cbar.gs
distributed with grads) which can change font size from command line.
The usage is
'cbar1.gs <width> <height>'
where width and height in inches. Default is same as cbar.gs (0.12 and
0.13). If you specify only width then height is 0.01 higher than that.
Hope this helps,

* Script to plot a colorbar
*
* The script will assume a colorbar is wanted even if there is
* not room -- it will plot on the side or the bottom if there is
* room in either place, otherwise it will plot along the bottom and
* overlay labels there if any. This can be dealt with via
* the 'set parea' command. In version 2 the default parea will
* be changed, but we want to guarantee upward compatibility in
* sub-releases.
