Hi,

I have issues plotting functions that rely on if-Statements. With the following code and anything similar, i always get "function is not defined", although i can calculate single values without a problem.



Also, i found another minor issue:

When changing text sizes, the newly selected size stays at that value, regardless which other object (with a different textsize) gets selected.

Example:

Label "Test", mark it, change its font size to 12 (from 10). Then, Create Label "Test2", font size dropdown still displays 12, although the text is 10px high. Selecting the dropdown and clicking on 12 sets the text to 12px. I think this is just missing a query for the selected object's textsize.

If this should be in another thread, sorry but i didnt want to open 2 threads just following registration.

Greetings.

Hello lilithpro,

Just a suggestion. The recent beta version (0.89_6) will make the plot. Pay attention in cases like this to use "eval" function or numerical optimization if you need numbers (in order to avoid symbolic processor). For instance, using your numbers:
This will fail:
a-b*c^74—#@#
Saying that the maximal number is excited
But this will do not:
a-b*c^74=457.9239
eval(a-b*c^74)=457.9239

In order to see both part of your function, use this
f(x)←if(x>70.6,eval(a-b*c^x),eval(d-e*g^x))

If you did not do this, there is no guaranty that you will even see the x>70.6 part of this discontinuous function
