Dear all,
I am using the code of spmap by Stata SE 16.0,but here some problems. The example data are as follows(just a part city of China):
Code:

Where I use the code is "spmap", more details as you can see:

spmap value using china_city_coord.dta, id(ID) ///
fcolor("252 255 164" "252 181 25" "237 105 37" "187 55 84" ///

ocolor("black" ...) ///
clmethod(custom) clbreaks(0 14 28 42 56 70 84) ///

graphr(margin(medium)) ///
subti("2019 年中国市级行政区划", color(black)) ///
caption("版本 2.0 | TidyFriday 出品", size(*0.8)) ///
osize(vvthin ...) ///
legend(size(*1.3) ///
order(2 "0～14" 3 "14～28" 4 "28～42" 5 "42～56" 6 "56～70" 7 "70～84") ///
ti(示例数据, size(*0.5) pos(11) color(black)) color(black)) ///
line(data(mybox_coord) size(*0.5 ...) color(black)) ///
xsize(13) ysize(10)

In the end, the map has many lines. I don't want to have such lines. So, how to solve it? What's more, the state 15 can do it well.
