Help please! Issue on 'grqreg'

[Kate Peng]

Dear all,

I am using Stata 11.
I tried to plot coefficients of a quantile regression by using command 'grqreg'.
commands are as follows:
-----------------------------------------------------
sqreg sale_price year buildmsr high_story d_1f d_type taipei_d dbank dmrt dschool dbad,quantiles(10 20 30 40 50 60 70 80 90) reps(20)
grqreg, ci ols olsci
--------------------------------------------------

What confuses me is that the graphs are quite different from what I saw before... These graphs have several 'diamond' shapes along the quantiles. I don't know what seems to be the problems.

Any help will be deeply appreciated.
