Re: Tk:: Graph menu not working to change the type of graph

[hgolden]

Hey,

So I can't run your program because I'm missing the data, but the first thing to try with things like this is calling $MW->update; after you change something. Sometimes that's all it takes.

Update: Why don't you try:

$ca->clear();
$setdisplay(whatever);
$ca->redraw();
$mw->update;

I don't know if that will work any better, but it does use Tk::Graph's methods, which you might need to do. Maybe you can't change the type while the graph is drawn...

Also, the below posts are right, you should post your complete code, or at least a working version, so we can help you better.

I tried adding that in the function setdisplay, underneath $ca->configure(-type => $typ); but it didnt' work. The console behind my graph, prints the message

ERROR in Tk::Graph:Tk::Graph::set #947: Option '-type' is incorrect! (
+) at /home/others/it/itwi/perl/lib/perl5/site_perl/5.6.1/Tk/Graph.pm 
+line 1802, <IN> line 9318.
Bars

The last line which says'Bars' is the contents of the $typ variable being passed to the setdisplay function. Which whould be correct, I don't know why it is reporting -type is incorrect?
