How do I remove vertical lines from stem() and combine plot()? -

-

so got sample code.

x = linspace(0,1,5); y = x.^2 + 8*x; u = [2,1,3,9,3]; figure axis([0,10,-100,100]) stem(x,u) plot(x,y)

can tell me

1) how remove vertical lines? want make scatter plot

2) how combine curve $$y = x^2 + 8x$$ , scatter plot? having hard time finding correct commands.

3) , equivalent of "axis" stem?

  1. in matlab, apparently there command called scatter same parameters.

  2. hold on command to

figure

stem(x,u); hold on; plot(x,y);

3. axis should last thing in plot

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
