[erlang-questions] how: ot: real time web pages?
Sun Dec 2 08:25:55 CET 2007
I start from what I would like to have:
A web page with a real time updated display of numerical values and
graphs. Think about typical process displays in industry,
temperatures, voltages and some graphs showing parameter history.
Maybe some graphical layout of hardware, to show how each parameter
is connected to each other.
To achieve that, I would need a web page template format, where I can:
- define named text fields, which shall be updated
- define named graphics, which can be updated
- and some code to generate the real page and connection functions
for (comet style?) communication with the page and erlang process
feeding the data
Currently I have all that implemented as Tcl/Tk canvas (thanks to Ola
Samuelsson and ewish, which was distributed with Erlang back in 97 or
get a hint on how to do this. Googling shows a lot of options, most
and svg, changes updated via attributes. Or canvas tag (complicated
with text fields?) Or haxe and flash (for which I did not find
examples, how the update mechanism would work) Or something else?
Is this doable? Some examples existing already?
