Mask and Limits Testing

[kienle99]

Hello everyone, I want to ask about how to make a chart, please help me!!!

Pic 1: I have a database to display this chart and it is this indicator (Pic 2)

Pic 3: I create this chart but it is not same type.  

Problem : So i want to make a chart(Pic 3) but use database, or how to change indicator (Pic3) to indicator(Pic2). 

I am not good English so acting is a bit bad. I am sorry for any inconvenience this has caused you. Thank you.

How are all those "database" and "pic1/2/3" related to your header line of "Mask and Limit Testing"???

And what exactly is "Pic1", "Pic2" and "Pic3"?

Where exactly do youhave charts? In your images I only see a XYGraph…

Thanks for answer,

Pic = Picture (Sorry ,my habits)

Those " database" in SQL server create a line in XYGraph(Picture 1) but XYGraph is not have limit as Test Alarm (Graph in Picture 3 have the limit lines (1 pink, 2 green)). So I want to make XYGraph has the limit lines as Test Alarm.

The problem was understand what you meant by "Pic1" "Pic2", but the fact that you in-lined a bunch of pictures awkwardly without labeling them to know which is 1, 2, 3,   or the fact you actually have 4 of them.

And none of those pictures show anything about databases or even a SQL server.

Hi kienle,

as RavensFan explained: you inlined 4 images without any description/labels in your message, but in the text you referenced them by arbitrary names…

That graph in your image shows 4 plots (as far as I can tell from an image).

When you want to replicate that image in your VI then your XYGraph should also contain 4 plots…

Thanks for answer,

I will simplify,

I want a graph ( X: real time; Y: collect value from sensor). Pic 1( mark with cricle is graph)

 but that graph has limit lines( mark with cricle in Pic 2). Limit line has 3 upper limits

Help me with your example. Thank you

Hi kienle,

as I wrote before: you need to create an array of plots for your graph...

[kienle99]

The problem in this VI. Please help me
Thank you, Sir

Hi kienle,

it's always a bad idea to rely on ExpressVIs and DDT wires…

Your XYGraph expects plots consisting of [x, y] points, so you need to convert the DDT wire into such a plot:

(When your "database" source gives you evently distributed samples over time then you might go the other way around by creating a waveform instead of an XY plot from your database data.)

Thank you,Sir
That is not answer I want but I will follow your advice.
Thank you again for everything you've done
