c# - 150K rows for scatter plot graph loading forever? -

i have 150k records of x , y columns , trying draw chart finanicalformula. taking time create chart ever. not throwing error also.

chart1.datasource = dtchart       ' data bind selected data source       chart1.databind()       chart1.chartareas(0).recalculateaxesscale()   chart1.datamanipulator.financialformula(financialformula.forecasting,                           "linear,,false,false",                           chart1.series("series1"),                           chart1.series("linear"))    chart1.datamanipulator.financialformula(financialformula.forecasting,                           "exponential,,false,false",                           chart1.series("series2"),                           chart1.series("exponential"))   chart1.datamanipulator.financialformula(financialformula.forecasting,                           "islogarithmic,,false,false",                           chart1.series("series3"),                           chart1.series("logarithmic"))    chart1.datamanipulator.financialformula(financialformula.forecasting,                           "power,,false,false",                           chart1.series("series4"),                           chart1.series("power"))   chart1.chartareas(0).axisx.minimum = 0   'chart1.chartareas(0).axisx.intervaloffset = 0.1   chart1.chartareas(0).axisy.minimum = 0   'chart1.chartareas(0).axisy.intervaloffset = 0.5

control coming out these line in debug. after page taking load data on graph. how can resolve this?

the easiest way if can find way reduce point count in data preprocessing (i.e. combining several data points in proximity each other single data point) - interestingly enough dundas has relevant articles on support pages:

  1. improving performance in dundas chart large data sets
  2. grouping data

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.
