Data Dashboard App limitations

[Rusbas]

I have an application where a central logging Windows PC/Labview needs to make data available for display on several users' displays.

Touchscreen devices offer the best solution for the environment and I'm assessing tablets running the Data Dashboard app vs touchscreen Windows tablet PCs running labview code.

The requirement is very flexible in that the users should each be able to view a selection of a large number of variables against each other or time and also choose the time period for display.

I can see the data dashboard app is in ongoing development and I've tested it with some trial data including multiple line plots and being able to zoom and scroll the displays as well as controlling shared variables to select the data to be graphed.

However I'm coming around to the conclusion that I need to go the full tablet PC route to use the full power of Labview to make a suitable UI.

I'd just like confirmation of the following current limitations of the Data Dashboard:

i) I can only have one Y axis on multiplot graphs/charts. (and can't specify individual colours for plots)

ii) It's not possible to simply supply a timestamp along the X axis.

iii) Things like 3D plots are currently impossible!

iv) I will have about 20000 points for each of at least 10 variables and this seems to slow the Dual Core 1.5GHz/ 1Gb RAM tablet I'm currently using. Would more processing power/memory help this?

Many Thanks for reading.

Hi,

As far as I am aware, you are correct in your conclusions. I haven't verified all of them (don't have a tablet in front of me!), but certainly it isn't possible to have a 3D graph, or to plot multiple axes.

The requirements you have (viewing large numbers of variables in different configurations), makes me think that DD may not be the most suitable application for what you need.

The windows tablet PC could run a labview executable which connected to your variables or a web service, making your UI completely customisable. Another possibility is to build an html version or something similar to integrate to labview web services, but that may depend on what you are most comfortable developing.

Actually, you can have multiple axes per plot in WebPager...
