XY graph plot colour

[franz_73]

Hi All,

I have a problem with the XY Graph representation.
I'm trying to show different plot with different colours in the same graph.
I realized a VI (8.2 Labview version), but it is wrong because at every iteration all the trace are re-colored with the same
colour.

I have two 1D array (X array and Y array) and my goal is to show every (X,Y) point with different colours.

Could please someone help me?

I attached the VI and a Front Panel screenshot.

Thanks in advance for your support,

Francesco.

Please give more information why you want to do this.

If I understand it correctly you want to display every point with a different colour on your graph.

Please take a look at this. Hope it helps.

Hi Stefan,

you have understood correctly.

I want to represent, on the same XY graph, points with different colour (it ins't necessary every point with different colour).

Application: I have a network of 10 sensor (10 for example) and I need to capture the temperature per each sensor.

Then I select two temperature, Tmin. and Tmax. from my front panel, and I would like to show all the sensors on the same graph in this way:

1) sensors with  T<Tmin              -> blue colour    (freeze)

2) sensors with  Tmin<T<Tmax   -> green colour  (in range)

3) sensors with  T>Tmax             -> red colour     (hot)

The VI which I attached is a sinmplifyed version to make the issue understandable.

Thanks for your reply,

Francesco.

Francesco,

Could you please un-mark your reply as the solution (look undr Options in top right corner)

and

Mark NitrinD's reply as the solution?

It helps others find the solution faster in the future and it adds to NitrinDs solution count. As volunteers we only get paid with "Kudos" and "Solutions".

Thank you,

Ben

Hi Ben,

I have just un-marked the solution.

This is my first post, sorry for the inconvenient.

Best Regards,

There is a Express-VI that might be interesting for you, called "Mask and Limit Testing". Not sure it it's available in 8.5 because I'm using 8.6 but it should be.

You can take your signals you wire into your graph and set an upper and a lower limit andand the graph will change it's colour when he's outside the limits.

Cool!

and mark NitrinD's messsage so he gets credit for the solution?

Thank you and welcome to the Forum!

PS Stephen. I have a pointed hat at home with that same pattern. My wife brought it home with her after a buisness trip since I was born in Munich.

Hi Nitin,

just the last question, I tried your work with LabView 8.5 and it works fine.

Reproducing it with step by step  I have problems to create the bundle by name output with X and Y array.

In the bunble I can view only the Y array, two times (view screenshot attached).

Probably I'm creating in the wrong way the  block on left-top of the block diagram (the input cluster in the bunble).

Could you provide further explanation?

Thanks for your patience,

Francesco.
