Graph Extensions for LabVIEW

[Mike_King]

Overview
This example allows real time feedback and mouse actions on any graph and one can easily add them to the project with existing graphs and data to improve them.
Description
Currently, there are 6 main extensions:

• Cursors - Show real time overlay of data values and time at the cursor and plot intersections
• Graph BGK Colors - Lets one set bgk color where the minor and major grid colors are
• Peaks and Valleys - Allow one to highlight on the graph any # of peaks and valleys from the data
• Markers - Interactive labels and regions to mark up the graph.
• Mouse Zoom - mouse based scroll zooming for graphs
• Plot Highlighter - for when one need to visually highlight a plot (on change or user selection or new data for example)

So, the code is available as open source on GitHub:

Requirements

• LabVIEW 2012 (or compatible)

Steps to Implement or Execute Code

1. Open the Graph Extensions 2012 NIVerified.lvproj.
2. open any of the main VI and operate according to the instructions.

Hi Mike,

Great Job!

Thanks for sharing and posting a video.

Is it possible to convert it to LabVIEW 2014?

Thanks,

Ryan

BTW: this library is in the tools network now and is available in 2013.  You can also grab it from github for the latest developer builds.

Hi Mike,

Could you provide a link for this library on the tools network? 

I can not find it with searching.

Very nice graph additions by the way, thank you very much for making this.

Regards

I never published it in the tools network, too time consuming.  Its available for download on github, links at the top of post.

I see. I will look at github. 

Thanks.

Hi Mike_King,
I want to thank you very much , really nice job.

I wanted to use your graph tool and use a normal graph(waveform graph) instead of XY Graph but it does not work I I give  you the pictures of my proramme for you check What is missing, I need your help too much, this tool in my project of my university ?

Thank you for your help.
SARAH.

Hi, there are a lot of references to change and fix with different graph types as well as a few different methods for the XY coordinates that are different so you'll have to dig into that if you intend to change the graph type.  This is exactly why I used an XY graph, its easier. I would actually suggest converting your waveform data into the same formats as the XY grpah supports, which would be much easier than changing the whole library and many methods to support the waveform graph type.  Plus, you have to know which datatypes you want to build/support for waveform, since they actually support quite a few formats and the XY interpolators will have to adjust for each type.

Hi Mike_King, 
Thank you for your help, Unfortunately that does not work with waveform Graph ,i wait to improve your program,
In my situation I wanted to display a table of 2D in XY Graph, it works perfectly with the waveform graph but I dont think than it will also work with the XY graph ??
If i was able to display this array of 2D in XY graph i will have solved my problem!!
thank you for your attention .

[Sarah_LAB]

It's fine, thank you
I found the solution
