，比如數(shù)字顯示,儀表,儀表、指示燈、圖表和圖形來放置控件和數(shù)據(jù)顯示為你的系統(tǒng)。當你完成并運行你的虛擬儀器時你通過操作這前面板去控制你的系統(tǒng)是否移動了一張放大的圖片或者用鍵盤輸入了值。ConstructtheGraphicalBlockDiagramToprogramtheVI,youconstructtheblockdiagramwithoutworryingaboutthesyntacticaldetailsoftext-basedprogrammingIanguages.Youdothisbyselectingobjects(icons)fromtheFunctionspaletteandconnectingthemtogetherwithwirestotransferdataamongblockdiagramobjects.Theseobjectsincludesimplearithmeticfunctions,advaneedacquisitionandanalysisroutines,networkandfileI/Ooperations,andmore.構建圖形框圖在虛擬儀器框圖上編程你構建框圖，不用擔心它的基于文本的編程語言的句法細節(jié)。你通過從功能控制面板和連接在一起的導線之間傳輸數(shù)據(jù)框圖的對象來選擇對象(圖標)而完成構建框圖。這些對象包括簡單的運算功能 ，先進的采集和分析程序、網(wǎng)絡和文件I/O操作等等。DataflowProgrammingLabviewusesapatenteddataflowprogrammingmodelthatfreesyoufromthelineararchitectureoftext-basedprogramminglanguages.BecausetheexecutionorderinLabviewisdeterminedbytheflowofdatabetweennodes,andnotbysequentiallinesoftext,youcancreateblockdiagramsthatexecutemultipleoperationsinparallel.consequently,LabviewisamultitaskingsystemcapableofrunningmultipleexecutionthreadsandmultipleVIsinparallel.數(shù)據(jù)流編程虛擬儀器使用一種專利數(shù)據(jù)流規(guī)劃模型來釋放你的基于文本的編程語言的線性結構。由于執(zhí)行命令的數(shù)據(jù)是由節(jié)點之間的數(shù)據(jù)流,而不是按序貫行文本，你可以創(chuàng)建執(zhí)行并行多重操作的框圖。因此虛擬儀器是一種在并行方式下有能力執(zhí)行多重執(zhí)行線程和多重虛擬儀器可見的多重任務系統(tǒng)。ModularityandHierarchyLabviewVIsaremodularindesign,soanyVIcanbyitselforaspartofanotherVI.YoucanevencreateiconsforyourownVIs,soyoucandesignahierarchyofVIsandsubVIsthatserveasapplicationbuildingblocks.Youcanmodify,interchange,andcombinethemwithotherVIstomeetyourchangingapplicationneeds.模塊化和層次結構虛擬儀器可見化是一種模塊化設計，因此一些虛擬儀器可見可以是虛擬儀器本身或者作為虛擬儀器的其中一部分。所以你可以設計VIs和subVIs的層次來作為應用程序構造模塊。你可以修改、互換、和其他VIs結合來滿足你不斷改變的應用程序的需要。GraphicalCompilerInmanyapplications,executionspeediscritical.Labviewistheonlygraphicalprogrammingsystemwithacompilerthatgeneratesoptimizedcodewithexecutionspeedscomparabletocompiledprograms.YoucanevenusetheLabviewprofilertoanalyzeandoptimizetime-criticaloperations.Consequently,youincreaseyourproductivitywithgraphicalprogrammingwithoutsacrificingexecutionspeed.圖形編輯器在許多應用程序軟件中，執(zhí)行速度是很重要的。虛擬儀器是唯一的一個產生其優(yōu)化速度可比得上編程程序的編譯器的圖形化編程系統(tǒng)。你甚至可以運用虛擬儀器分析器去分析和優(yōu)化時間至上的操作。結果，你在沒有以犧牲運行速度的圖形化編程的前提下提高了你的運行效率。MeasurementsandMathematicsLabviewincludesavarietyofothermeasurementanalysistools.Examplesincludecurvefitting,signalgeneration,peakdetection,andprobabilityandstatistics.MeasurementanalysisfunctionscandeterminesignalcharacteristicssuchasDC/RMSlevels,totalharmonicdistortion(THD),impulseresponse,frequencyresponse,andcross-powerspectrum.Labviewuserscanalsodeploynumericaltoolsforsolvingdifferentialequations,optimization,rootfinding,andothermathematicalproblem.Inaddition,youcanextendthesebuilt-incapabilitiesbyenteringMatlaborHIQscriptsdirectlyinyourLabviewprograms.Forchartingandgraphing,youcanrelyonthebuilt-inLabview2Dand3Dvisualizationtools.2DtoolsincludefeaturessuchasautoscalingXandYranges,reconfigurableattributes(point/linestyles,colors,andmore)andcursors.MicrosoftWindowsuserscanemployOpenGL-based3Dgraphsandthendynamicallyrotate,zoom,andpanthesegraphswiththemouse.測量與數(shù)學虛擬儀器包含了許多其他的測量分析工具。例子包括曲線擬合信號的生成、峰值檢測，概率和統(tǒng)計測量分析功能可以確定信號的特點，例如 DC/RMS水平，總諧波失真(THD，脈沖響應，頻率響應，互功率譜。虛擬儀器的用戶也可以部署數(shù)值工具，優(yōu)化,解決微分方程根的發(fā)現(xiàn)，和其他的相關的數(shù)學問題。另外你也可以在你的虛擬儀器程序中通過直接進入 Matlab后者HIQ原稿來延長這些內置的能力。為了制圖和繪圖，你可以依靠這內置的虛擬儀器 2D和3D的可視化工具。2D工具包含的特征功能有如自動縮放X和丫的范圍、可重構屬性(點、線款式、色彩，以及更多)和游標。MicrosoftWindows用戶能夠使用基于OpenGL的3D圖形，然后動態(tài)縮放、旋轉、和用鼠標移動這些圖。ComplexMeasurementsMadeEasyDespitethecomplexityoftheunderlyingalgorithmsthatimplementthesefunctions,youwillfindthemeasytouse.Forexample,asetofbuilt-inmeasurementfunctionsusesthenewwaveformdatatypetoacceptre—world,time—domainsignalinputsdirectlyfromDAQhardwareandreportresultsreadyforcharting,graphing,orthenextstageofsignalprocessing.復雜測量的簡化盡管實現(xiàn)這些基本功能算法的復雜性，你會發(fā)現(xiàn)它們是易于使用的。例如
