view graphs

Hallo All,

        I have 5 rakes each having 5 probes, so in total 25 measurements.

Rake 1: PVE_1C1, PVE_1C2, PVE_1C3, PVE_1C4, PVE_1C5

Rake 2: PVE_1J1, PVE_1J2, PVE_1J3, PVE_1J4, PVE_1J5

Rake 3: PVE_1S1, PVE_1S2, PVE_1S3, PVE_1S4, PVE_1S5

Rake 4: PVE_1U1, PVE_1U2, PVE_1U3, PVE_1U4, PVE_1U5

Rake 5: PVE_1X1, PVE_1X2, PVE_1X3, PVE_1X4, PVE_1X5

Through DAQ system the vaues of these measurement names are recieved along with a time stamp. I have plotted the XY graph with x axis as time and y axis as values for each rake. I have control for which rake has to be plotted. When i Change the rake number the graph starts freshly. I wanted the graphs to plot continously and i can switch the view to which ever rake graph i want to see. Please find the images for reference. Thanks in advance.

Hi Hari,

all we can say from your BD image: You need to change your data buffering and display…

Hallo Mr.GerdW,

        Thanks for the reply. I am very beginner. I would be glad if you can provide an example or screenshot of how to change the buffer and display. Sorry If Iam taking lot of your time. I highly appreciate your help.

Best Regards

Hi Hari,

right now it seems you create a new buffer each time you switch the case.

You need to change it so you store all measurement values in your buffer. The user than just selects, which signals should be displayed in the graph - the signals will be get from the "whole" buffer…

Hallo Mr.GerdW,

       Thanks for the solution

Why not use the build-in plot visisibility property

LV2012 has a bug in the legend , the first plot can not be disabled by a checkbox ....    so another way is shown (that could be improved however it works .....

View Listbox is set to 1 or more Items .....

Hallo Mr.Henrik,

Thanks for the solution. I think your suggestion was about plots in a graph. My problem was, I had a case structure controlled by an Enum. When I change the case by Enum, the graph starts freshly for the new case.

Hallo Mr.GerdW,

      Suppose i have mutliple graphs (for example 10 XY multi plot graphs). I dont want to see all the graphs at the same time. How can I control viewing of a praticular graph which I want? Thanks for your time

Hi hariss,

you can use

- use the visibility property of the graphs

- put the graphs on different tabs of a tab container and switch between those tabs

- put the graphs in subpanel VIs in a subpanal container

- use only one graph and change the data that is visible in the graph…

Hallo Mr. GerdW,

  Thanks for the instant reply. 2nd option suits me best.
