<div>Dear Barth,<br>
<br>
I produced a very small example that produces the message (using
Kst-2.0.x-2015.01.11-06.04, under windows 7)<br>
</div>
Here it is:<br>
<div><br>
Time;Var1;Var2;Var3;Var4<br>
1.89;0.109125;0.1717501;0.1248751;-1.5<br>
1.9;;;;-1.5<br>
<br>
</div>
<div>After loading these very few data (using ";" as data
delimitor and "." as decimal separator), if you plot in the same
graph Var1, Var2 & Var3 as a function of time, then the
message appears.<br>
</div>
<div>The problem comes from the 3 data that are empty on the
second line, that is: ";;;;"<br>
<br>
</div>
<div>Of course one could argue that the data files should be
"clean" (i.e. without 4 successive ";") , but we do not always
have the control on theses files, they come as they are.<br>
</div>
<div><br>
I am not aware where I should open a bug report, please let me
know so that I can do it. <br>
</div>
<div>Thanks<br>
</div>
JD<br>

Can you open a bug report with a example (small) data file that
triggers the messages?<br>
<br>
Thanks!<br>

<br>
I'm a new user of the kst software, I've now spent some
days using it.<br>
kst is really nice and impressive, but I'm facing the
following problem :<br>
Depending on the data files plotted, I can end up with a
slowness of kst,<br>
with the following message printed in the command window:<br>
QPainterPath::arcTo: Adding arc where a parameter is
NaN, results are undefined<br>
<br>
As far I understand this message is related to Qt, but
printing this message is what makes kst so slow in my
case.<br>
</div>
<div bgcolor="#FFFFFF" text="#000000">Does anybody know if
and how to turn off this message printing?<br>
Or anothzer way to solve this issue?<br>
