Insert strings (x and y) in graph

[marten]

I'm measuring from a network analyzer from Rohde & Schwarz and i read out the measurement data....

What i've got is the values of the y- axis (string) impedance, and the values of the x-axis (string) frequency

How can i combine them to one graph/plot?

Hello Marten,
if you get the aquired data as Strings, use the conversion functions from the String->String/Number Conversion palette. You can feed in arrays of strings and get arrays of Integer/Dbl (depends on what function you choose).
To present the data use the XY- Graph from the Graph palette.

How can i make a array of 2 elements (i'm using currently build array)

[marten]

i ment

1d array of cluster of 2 elements....

If you want to display one plot you do it like this:



Have a look in the LV help about XY-Graphs, there is an example VI (XY Graph.vi) which shows all possible ways to get data into the graph (there are quite a lot).

I'm trying to get the plot in the graph... and it happens...

But...

He only shows the point of the value and he don't show the total line.........

Hi Marten,
why don't you attach the important part of the VI, this would make things easier. Did you have a look at the example?

It sounds like you are reading a pair of values and immediately plotting them. The inputs to an XY Graph are an array and if you build a new array with each iteration, you erase the old values. To make an XY Graph behave like a chart (with history), then look at the shipping example called XY Chart.

"He only shows the point of the value and he don't show the total line........."

If you're seeing only one point then you're not feeding the graph a full array.  If you're seeing all the points but they're not connected then that is simply a plot option.  You can change the plots properties to show only the point, or you can choose to connect the points in various ways.  Right-click on the plot and check Visible Items > Plot Legend (it should be there by default).  Then right-click the plot legend and you will see options for plot styles.  Try the first choice for common plots for smoothly connected points.

This is it,

I've opened an example and the only difference is that he is out of the while loop, but when i do that he says that the memory full is....
