    Hello Expert , 

    just a simple question , i have a json file and formatted like in provided image , iam trying to get that json data numeric data in ross xpression , where datalinq can link automatically to next parameter as i go on air. in other word "Baltej Singh\player_path<2>\array" this is 2nd parameter link , as i go on air , i want to read data from 3rd , 4th , 5th parameter. 

    For Example

    Baltej Singh\player_path<2>\array for 2nd frame

    Baltej Singh\player_path<3>\array for 3rd frame

    Baltej Singh\player_path<4>\array for 4th frame

    Baltej Singh\player_path<5>\array for 5th frame

    Baltej Singh\player_path<6>\array for 6th frame

    and so on  

    i tried to macros function 

    Baltej Singh\player_path<@F ID@>\array

    Where F ID is a text object which value change according to frame 1,2,3,4,5 and so on 

    it work until i refresh datalinq everytime , and it is not changing automatically Which goes ON AIR 

    Please Show the way .

    Hi!

    Do you have the json file (or an offline copy) available? We can try it locally to see if it's just a Datalinq Key format issue.

    here is the json file link 

    i give my try with this idea,

    1. create a text object that is drive by sequencer position . (basically frame number of sequencer)
    2. i use that text object as macros in datalinq column.
    3. it work but not in real time. 

    as i play sequencer datalinq data update only once. but as i open datalinq and just press ok it update that time.

    I discuss something very similar here but using a widget which are global. 

    You would then link the text object to the widget but you should it will update in real time.

    json file

    Hi simon 

    i check that post but what iam doing is i had a json file which content multiple parameter in it. i had a text object which number change according to framenumber of sequencer  from 0-472 (text object name fnum), i have the same 0-472 total parameter in json file 

    i have another text object which is directly datalinq to json file 

    i change the macros in datalinq column section, 

    as per my knowledge now that datalinq column data need to change while play the sequencer and it need to show the json data parameter according to tha fnum value.

    but the problem is it is not doing so . 

    but if i click the set button in datalinq and click ok (without linking or doing anything else)  the data is updating according to fnum value

    Please find the image below

    You maybe running into a order of operation issue, visual logic runs after onOnline.

    if you check that youtuhbe video , may be it will more clear, the image is just for countdown for text for (like as your said earlier about widget, i took it from sequencer position) and it working perfectly ,

    but the macros in datalinq  it not working as like in video , it is updating only once rather then per frame .

    In your JSON Datalinq source, if you switch from "Wait for file change events" to "poll every 1 second". 

    Does it update live on air every second? 

    This is probably too slow for you, but I am curious if it updates on air if you switch to polling.

    Easiest way would be to update a widget each time you take on air until the maximum and then reset and use that widget to fill a text object and then use that text object as a macro. 

    I answered this recently on the forum. When I'm next at my PC I'll look for it.

    As far as when I have worked on this. including setup perspective camera angles. the main thing is there are lots of key data and multi-points in JSON to set up in xpression.

    in which if you keep it rum through macro. should it be a feasible thing. ?

    Might Ross expert guide me as well did we achieve and create platform in Platforma to give visuals to data points. ??

    looking fwd to learning in this as well.
