Graph selection box functionality.

  I am interested in drawing a selection box on the Graph control, like the one that can be drawn by the user in zoom mode.  Can I draw this selection box when I am not in zoom mode?

I was also wondering why questions here are not answered in the order that they are submitted...

Pyramid,

To answer your second question first, there are many reasons that forums may not be answered in the order they are submitted. First, the past two days were actually holidays for National Instruments' corporate offices, and therefore there is sometimes a longer lag time with this. Second, there is not just one person who goes through and answers all of these forums and there is a difference in both schedules and other tasks (since forum support is not the sole job of an Applications Engineer) and there is sometimes other things that are done before hand. Third, not all questions and posts are quick to answer. Our Applications Engineers sometimes have to research an issue and find the best solution and give the best amount of information. If we were to just answer these questions in the order they were received, there is a good chance that nothing would be answered for quite sometime, especially if we are having to escalate the issue to our R&D department or other escalations. Fourth, some forums are answered by other employees than Applications Engineers such as members of our R&D team. While Applications Engineers are in charge of answering forums when an answer is not posted after 24 hours, our R&D team and other employees will frequent the forums and sometimes help out when they know the answer to a question. In this case, they are providing their feedback and help on their own and may not go through all forums and respond to every one. Finally, realize that these forums are public discussion forums and are handled quite a bit from our users as well as our employees. While we do help with issues on this forum, our support structure has other options as well. We have both email and phone support available and if you would like to speak with someone sooner than these forums are providing, you do have that option as well.

Looking back, I see that there was only one forum answered by an Applications Engineer which came in after your post was submitted (as I am writing this). This was actually a post which focused on DAQ and not specifically Measurement Studio. DAQ is supported by another team than Measurement Studio's UI and Libraries and therefore there are sometimes other teams answering posts on this forum. This should not be seen as you being ignored, as other supporters may not have the knowledge to help out with your issue, but instead please be patient and someone should get to your post as soon as an answer is found.

That being said, I was able to research this issue this morning for quite some time and found there is not a way to have this ability to have a selection box unless you are using zoom. My question to this would be, what exactly would this selection box do? Would you want to be able to copy data or delete data? What other type of use would you expect from a selection box on a graph? If you let us know what your end use for this would be, I would definitely be willing to submit this feedback to our R&D team for future releases. I am just not sure what use this would have for this?

Pyramid,

I actually found some useful information from previous forums. I had replied prematurely as I saw you were needing a response, but I was able to talk with R&D and we found these links.

These give some information about doing this. Some of this is in VB 6 but the concepts are still the same.

Thanks Brandon.  I wasn't trying to imply you guys were ignoring my question.  I was just being a wiseass, which I am guilty of from time to time.

The application for such a selection box in my case is peak detection on a ROI within a spectrum.  The user highlights an area, and all points within that area are examined.  I saw that you guys had the selection box available in the zoom function, so I figured you would make it available generally.

The links you gave me are exactly what I need.  Good work.  Sorry about the wiseass-ness.
