3 seperate "1d array of cluster of 2elements" combined on xy graph

[Schulke]

Hello, I am new here,

but I have a problem with my programming.

I've searched the forum and tried some possible solutions, but nothing helps.

I try to program a application, which contains three

primary functions.

1. Get a stepresponse from a real machine

2. calculate lines to ident the parameters

3. simulate stepresponse with the idented parameters.

If I test the system, the content is OK, but i got a problem with the XY-Graph...

I setted it up, that it should draw three graphs, but it only gaves out one graph in the

color of the first plot...

How can I make it, that the XY-Graph-Output know, which data belongs to which graph?

Thanks a lot for the answers...

To clarify my problem I made an screenshot.

Please excuse my bad english.

normally, if you display an array of 3 graphs (clusters of x and y arrays), the display on the x-y graph should be 3 plots, with the colors set in the plot legend.

could it be that your graph is not x-y graph? or that the plots 2 and 3 are set to invisible? or simply out of range?

Hmm, shouldn't be out of range, because
when i wire it seperately, the graph will be shown.
I visualized it in this way:

At the first time i used a selector to switch between the first 2 signals,
then they were printed both red and with Lines...
But i want the second graph in green and without lines, just dots...

If I want to build an array, I get the errormessage, that the array
and the xy-graph have different dimensions, but I think, when
they will be shown if wired seperately, it couldn't have different dimension...

[Schulke]

In properties the Option
'Plots shown' is set to '3'

I don't know ho to dis-/enable an plot...
Sorry

[Gabi1]

could you post your application?

[Schulke]

Sorry, just found this freehoster...
I don't have any webspace.

No need to find a web host. Just click the Browse button next to the Attachment box below the message body.

Oh shit...
Didn't see it yet...

This is the latest Version...


But... Editing isn't possible for me?!

Hope, the Host application is all you need,
can't upload archives

ok your first problem is pretty simple:

the build graphs express vis gives as output an array of clusters (each cluster includes 2 arrays, one for x values, one for y values).

when you combine 3 such arrays, if you dont concatenate the inputs, your combination will be a 2D array of graphs, that cannot be handled by the x-y graph

easy solution: right click on the build array -> concatenate inputs.

however, several graph inputs comes from case structures which are not terninated in the false case - you might want to check into that.

Gabi is right. You don't have a:

...3 seperate "1d array of cluster of 2elements" combined on xy graph ....

as you say in the title.

You have 3 seperate "1d array of cluster of 2 arrays", each element in the (toplevel) 1D array is a plot with several points, so concatenating the arrays will give you a 1D array that has as many plots as the sum of plots in each individual 1D array.

So Gabi's solution is correct.

(Further clarification: XY graphs cannot handle 2D arrays. For example if each plot is in one of the other legal plot data formats (1D array of a cluster of xy points, 1D complex array), you also cannot use "built array", but in these cases you can use "built cluster array" (see image). This does not apply to your situation, though. ;)).
