Hi all,

I have an example where I see the output of three blocks in a wx time  
sink:

[http://web.eecs.umich.edu/~anastas/docs/wx.png](http://web.eecs.umich.edu/~anastas/docs/wx.png)

I didn’t get the expected result and I run in also with qt time sink:

[http://web.eecs.umich.edu/~anastas/docs/qt.png](http://web.eecs.umich.edu/~anastas/docs/qt.png)

The two pictures are different!  
The wx time sink does not seem to align the three signals properly…  
(I double checked this by also outputing to a file and confirming that  
the qt picture is the correct one)

Any suggestions?

thanks  
Achilleas

Yeah: Use the QT widgets.

As we keep mentioning, the WX widgets will be going away in the future,  
and no one wants to maintain them. Of course, if someone has a bug fix  
for this, that would be even better, but please don’t rely on the WX  
GUIs in the long run.

Cheers,  
M

Not yet. It’s not a terribly difficult one to conceive of. My only issue  
is  
trying to squash it into the current time\_sink blocks or just create a  
separate strip\_chart class for this. The latter means more code to  
update  
later, but it might simplify the logic that would appear in a work  
function  
that’s trying to be both things.

Understood.

Most of my tuits are still all rectilinear as well…
