Creating an Array based on Max and Min

[pirates712]

Hi,

I found a somewhat similar thread, but it didn't answer my question. 

I am building a Vi that will simulate a cyclone running at different inlet volumes. I need to generate a series of inlet volumes based on a user-input of max, min, and interval/step. This data needs to be used for both the calculations and the x-scale of a graph. What is the easiest way to do this? I could have the user specify each data point, but that only works if the user only wants like 10 data points. I need to be able to say, start at 0 and increment by 1 to 900. I know how to do this in matlab, but I can't figure it out in labview. 

Thanks in advance for any advice.

Use the Ramp Pattern function.

EDIT: Had posted a picture of a VI that I had for 8.2 that calculated the delta based on a start/stop/step inputs. However, in LabVIEW 2010 the Ramp Pattern has an alternative version that you can specify it by delta.

I'm using Labview 7.1 express, which is old but we already have it. I can't find that particular vi, I don't think it was included in our version of the software. Is there a way I can add it, or do I have to use an alternate method?

It's still there. Even back in LabVIEW 7.1 the functions palette had a search capability. Did you try it?

With 7.1 if you want the inputs to be start/stop/step then you can do something like this (the icon for the Ramp Pattern VI will look different for 7.1):

Woohoo! Thank you! I was trying to search for it using the vi help tool. It kept coming up with a "could not find page" message.
