if you are running Inkscape 0.48 then you will probably also need to
update the inx file as well, attached is the latest version from trunk

Thanks! I just installed the patch on Inkscape 0.48 into
/usr/share/inkscape/extensions/
and tried it. It works nicely, i.e. I got the notification.
M.

Hi Martin,

Just to confirm... Did you draw a rectangle before using the plotter?  The 
function-plotter requires you to select a plotting area before you tell it to 
render a function.  In other words, please could you confirm that you use the 
tool as follows:
* Draw a rectangle
* Select the rectangle
* Choose the function plotter extension, enter details and hit Apply.

I also noticed a couple of potential problems with your input fields:
* You're only using 2 samples... i.e. your sine curve will only contain two 
data points.
* You selected a y-range of 0:1 but the sine function has a range of -1:1.  
This means that the curve will extended below the bottom of your selected 
drawing rectangle.

Hi Alex,

Sorry for my incorrect report. Now it works. I was ignoring the
rectangle; I somehow thought that it was not mandatory to create and
select a rectangle.

However, I guess that in future it might be convenient to add a
notification to user in such cases. (Please draw and select a rectangle
first.) I understand of course that there are more important things
first to be solved.

Thanks and sorry again.

Martin.
