shapefile - Separated by the Meridian polygons in geomaps SAS VA (SAS GRAPH) -


i'm trying create custom maps russia in visual analytics. so, i've faced trouble of "separated region".
can see visualization of problem using dal'nevostochnyy (dvfo) region mapsgfk library. enter image description here

i tried fix scatter code:

data mps.vaasia1; set mps.vaasia1; if long < 0 , isoalpha2="ru" long=long+360 ;  run;

and result (on picture imaged region chukotka, dosen't matter):

enter image description here it's better previous situation, it's crutch.
i've try combine 2 polygons using gremove (also add paramether fuzz), result same.

upd:
use code coordinates:

data ch; set mapsgfk.russia; id ="ru-77" ; if long le 0  long=long+360 ;  x=long ; y = lat; run;

enter image description here

so question is:
how can delete space between 2 separated regions?

thx answers / comments.

this seems work, @ least specific issue. issue segment not same these, border. doing in more general way i'm not sure if there's way or not; there better way, perhaps using gproject, avoid issue entirely.

but works, @ least specific issue...

data vaasia1; set mapsgfk.asia1; if long le 0 , isoalpha2="ru" do;   long=long+360 ;    if segment=2 segment=1;   else if segment=7 segment=8; end; if idname =: 'dal'; *if long le 0; run;   proc gmap data=vaasia1 map=vaasia1; id id; choro id/nolegend; run; quit;

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

ios - Change Storyboard View using Seague -

i have following code checks connection server, , depending on want change views if no connection found. nsstring *connect = [nsstring stringwithcontentsofurl:[nsurl urlwithstring:@"http://myserver.com"] encoding:nsutf8stringencoding error:nil]; if (connect == null) { [self performseguewithidentifier:@"network_failure" sender:self]; } else { // other code here } my problem not change views. have added storyboard segue between 2 views identifier of network_failure . not have navigation controller or that, problem? thanks help! no not problem. first of all, in objectivec exists nil object oriented null . must use that. so: if(connect == nil) or better: if(!connect) so due fact nil not same of null , probably code does't enter in if scope . you have been able discover breakpoint. anyway: be sure set trigger segue (line) 2 view controller , , name network_failure (that not best name. should instead view1toview2 ) as, m...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
