The dialogs do not show correctly in the new Cocoa interface for Ipe. The reason is that no button bar is created in these dialogs (instead buttons are made "by hand").

This is what it looks like now:

Here is a patch that fixes the problem.

Hi,

I get the following error every time I try to plot a function, parametric function or even draw a coordinate system or grid.

I'm using Ipe version 7.1.10 and the latest version of ipeplots.

This works fine under Fedora 22 with Ipe version 7.1.7.

I do program, though I don't know Lua, but with some instructions I guess I could help to fix this.

I hope I am not asking a super stupid question, but here it is. Suddenly (it worked perfectly a few months ago) Ipe won't start on the same system and with the same Ipelets (I am using Ubuntu 18.04, and Ipe 7.2.7, and the ipelet I need the most is ipeplots):

It gives the message:
/usr/share/ipe/7.2.7/lua/main.lua:381: [string "/home/sonja/.ipe/ipelets/plots.lua"]:7: unexpected symbol near '<'
stack traceback:
[C]: in function 'assert'

[C]: in function 'require'
[string "require "main""]:1: in main chunk

If I delete all files from the .ipe/ipelets directory, Ipe starts normally. I reinstalled everything, including Lua 5.3, but to no avail.

I'm trying to draw the cosinus wave were all all values are in the plus range like this in geogebra:

I tried that in Ipe with the following settings:

But I'm getting this graph instead where the low points are differently high:

Is that normal or can I fix that somehow?
