Build an array and plot XY Graph for logged data in real time

[parthpanchal07]

Hello All,

Actually, I am new to the Labview and I am stuck at one problem.

Here, I have attached my VI's. I want to logged the centroid value in array and want to plot the XY graph. 

Apart from it if any body can suggest me how can I increase my image processing.

Any help would be appreciate. 

Thanks

Hello,

I am not quite sure were you have a problem, can you be more specific about waht you are stuck with ?

Otherwise, useful info on how to use the XY Graph : https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z0000019NAfSAM

In my VI you can see I am getting centroid value from subVI. 

1. I want to make to build an array of centroid values.

2. then I want to plot the XY graph continuoisly. 

Here, I am stuck.

When using an X-Y graph you have to keep your own graph history in shift registers.

Here is an example I did for someone with a similar question 

XY Graph2 will plot "live data"  XY Graph1 will mirror XY Graph2 after the for loop completes 

I know it's not a perfect example but I modified someone else's code to make it work...

Here is another example of an XY graph that plots live data, it is also an "action engine" sub-VI, and you can see shift registers are used to hold the graph history
