Showing graphical temperature with Tcl/Tk

I just started with Tcl and now also with Tk. But I like it and I
think it will supplant my Bash usage.
I already wrote a little script that shows my CPU temperature in a
console. But it would be much better to do this with Tk.
I measure the temperature every minute. I would think to show a graph
from the last 60 minutes and beside that the current temperature. The
last part I know, but any pointers about how to display the graph?

It sounds like you are looking for a stripchart facility. Both packages can do that.

Hi Cecil,

One of the demos is actually similar to your request:
https://github.com/auriocus/ukaz/blob/master/demo/linuxload.tcl
It displays a graph of the load average on Linux.

I'm also a bit biased as the author of yet another plot package called ukaz:

1) Install TkLib, use the 'plotchart' widget. Several wiki links:

#1 is the "I want a temperature graph with the least amount of work"
set of links. #2 is the "I want to know how to draw a graph from a
dataset" set of links (although reading the plotchart source would
likely help here slightly as well).

I am afraid I will not get bored soon. ;-)

The NOAA Weather Forecast page on wiki (http://wiki.tcl.tk/17514) has a graph of temperatures which you could use as a guide. It uses plotchart to do the heavy lifting. Checkout the procedure PlotTemp.
