Plotting multiplot chart on NI Dashboard

[JiaLuo08]

Hi there, I have two sensors for measurement and I would like the two datas from the sensors to be displayed on the chart on the NI dashboard, how do I do so? I've tried adding 2 plot in NI Dashboard chart, however it only shows one of the sensor data only.

Hi!

I have not used NI Dashboard before but I think it should work when you send bundled data from LabVIEW:

Let me know whether does it work with NI Dashboard?

Multiple Plots on Charts and Graphs 

You can now view multiplot data using the chart, graph, and XY graph. The chart and graph display 2D arrays of supported numeric values as multiplot data. The XY graph displays 2D arrays of points as multiplot data, where each point is a cluster that contains a pair of supported numeric values.  You can change the color of the plots by changing the color theme selected in the graph/chart properties. Sourced: https://decibel.ni.com/content/docs/DOC-29356

-So you need to ensure to create proper 2d array of data by getting data from each sensor and pass to chart.

Is this the correct way to create the array?

Hello,

Actually, that what you have created is called cluster, not an array, here you can read more about it:

Anyway, I was playing today with Data Dashboard and it is really cool stuff but... I couldn't figure out the multiplot neither. Did you manage to do it?

I have tried to pass a waveform, an array, an array of waveromes, none of these worked 😞

The Data Dashboard chart will show multiple plots when given a 2D array of numerics.

Hi Kracken,

On what platform are you using Data Dashboard?

In my case I'm testing on Windows 10 and I can see variables like Numeric or Boolean but when I use a 2D array it just doesn't show up in the Network Variables in Data Dashboard...

Multiplot on graphs is only available in Data Dashboard 2.0+ for iOS and Android tablets.

Hi Kracken, I've followed your example, but however, there's an error when connecting to shared variable. How to resolve it? Thanks.
