function plotter fails silently if called without selection

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.

Basic Usage instructions for the extension are in the manual:

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.

attached is a modified version of funcplot.py, which will raise a warning message if no rectangle is selected.

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.

committed to bzr rev 10370

Attaching upstream patch for backport testing in Ubuntu

Unassigning from Inkscape (Ubuntu) for now. Let's wait for the imminent upstream 0.48.3 bugfix release to be packaged before backporting any new patches.
