data visualization - How to display a stacked barchart in Gnuplot? -

-

i have data file looks bit this:

a 0.2  0.5 b 0.65 0.8 c 0.4  0.2

i.e., contains 3 columns first column contains labels , other 2 columns float values. columns separated spaces.

i'd plot in way labels appear tics on x-axis while columns plotted 2 differently colored barcharts on top of each other.

how can achieve using gnuplot?

assuming data stored in file 1.dat, stacked barcharts might generated follows:

set style data histograms set style histogram rowstacked set boxwidth 1 relative set style fill solid 1.0 border -1 set yrange [0:1.5] set datafile separator " " plot '1.dat' using 2 t "var 1", '' using 3:xticlabels(1) t "var 2"

as can see, barcharts no different histograms (at least, within gnuplot). more information can found on gnuplot demo page.

magically formatted comments change reported line number of javascript errors in browsers; this: //@line n "f" n line number , f file name. unfortunately, //@line appears ungoogleable. know there documentation on feature, , browsers support it?

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
