view tdms file in browser?

[david_jenkinson]

Hi,

I'm putting together a test which will save a tdms graph file containing current measurements and annotations.  If we wanted to view these tdms files within a web browser, would this be possible somehow?  It seems like there would need to be a browser plug-in for this.  Does one exist?  Has anyone accomplished this?

Thanks

The only plug-in I know of is the one for Excel.

There is no ready-to-use browser plugin at this point. How would you envision this to look like? Would you have a list of links, each of which represents a TDMS file, and when users click one of the links, the browser displays the viewer and the viewer loads the selected file? What kind of capabilities would the viewer need to have? Given that you probably don't want to move huge files around, would you need things like zooming or other user interactions?

LabVIEW provides various ways of exposing a VI on the web, including remote front panels or bitmap snapshots. Depending on your reqirements, you might be able to work something out based on these. Otherwise, my recommendation would be to create a LabVIEW RESTful web service, combined with a thin client web UI.

Hi,

I just got done typing a reply and lost it due to timeout.  😕

So I'll summarize,  yes we would have links to the tdms files, and the idea was to have the browser load the files and display in a web browser.  But there is a certain amount of customized data we want to return based upon manupulation of the cursors, which would require a custom vi, which we already do have. It is just that we'd like to be able to display the graph data either embedded in the web page (which doesn't seem possible at this point), or by clicking the link which points to the tdms file, and popping up either another window, or tab to display the data in a web page with the front panel of the vi showing which has the graph control.  I had not heard about the labviewRESTful option yet, seems like it has some promise in this application from my initial reading.  I guess the http request itself can contain the path to the tdms file, and our vi would act upon that and display it?
