Hello Smita,
I had the same problem a while ago and worked out the following:
1. Create a pdb-file which contains CA positions only, whereas the numbers
correspond to your wanted increments of colors. Be sure that CA's are
separated by a contant value, say 5 Angstroem.
example (30 zones):

2. Load this new pseudobar-pdb file into PyMOL, make bonds between increment
1 and increment 2 [increment 2 and increment 3 and so on...], define/assign
a smooth color for each increment (copy colors definition from automatically
created colors made by b-factor script) and show the b-factor bar as lines:
example:
========
load pseudobar.pdb
create zone1, pseudobar and res 1:2
create zone2, pseudobar and res 2:3
create zone3, pseudobar and res 3:4
create zone4, pseudobar and res 4:5
create zone5, pseudobar and res 5:6
create zone6, pseudobar and res 6:7
create zone7, pseudobar and res 7:8
create zone8, pseudobar and res 8:9
create zone9, pseudobar and res 9:10
create zone10, pseudobar and res 10:11
create zone11, pseudobar and res 11:12
create zone12, pseudobar and res 12:13
create zone13, pseudobar and res 13:14
create zone14, pseudobar and res 14:15
create zone15, pseudobar and res 15:16
create zone16, pseudobar and res 16:17
create zone17, pseudobar and res 17:18
create zone18, pseudobar and res 18:19
create zone19, pseudobar and res 19:20
create zone20, pseudobar and res 20:21
create zone21, pseudobar and res 21:22
create zone22, pseudobar and res 22:23
create zone23, pseudobar and res 23:24
create zone24, pseudobar and res 24:25
create zone25, pseudobar and res 25:26
create zone26, pseudobar and res 26:27
create zone27, pseudobar and res 27:28
create zone28, pseudobar and res 28:29
create zone29, pseudobar and res 29:30
create zone30, pseudobar and res 30:31
