Read and Write Problem

[PETER_AUT]

Hello!

I have a problem with the Data I/O in my program. The button "Animation" generates random numbers and saves them into a file. With the Button "Vergleich" i want to load the data and reproduce the data in the graph.

When i push the button "Vergleich" i can choose the data, but the program don*t reproduces it!

Coult anybody help me??

Hi,

Your count parameter on the read file.vi is 0 and so, it is not returning data.

That parameter should contain the number of elements you want to read.

Hope this helps,

Here are two changes, one uses the write to spreadsheet and read from spreadsheet file functions, the other changes your "read file" to "read text file"

P.M.

i have modified the program, that the program has two loops which generate the data. how can i  display two curves in one graph. i tried it but i always got the failure: that are two different data types.

what can i do, to display the two curves in one graph??

Hi,

You need to have all data sets in the array inside the cluster.

Check attachment,

Hope it helps,

yes is helped.

i have a question of understanding: Why did you index the array, the data from "Spreadsheet String to Array.vi" is a array???

The "Spreadsheet string to array.vi" is returning a double dimension array in the way you were using it.

So you have to index the array to get only the dimension with the data.

But of course we can use it in a different way.

Just tell the "Spreadsheet string to array.vi" to return a one dimension array like in the attachment.
