Graphics, Figures & Tables ⇒ TikZ comments

[layuval]

Hello everyone,
I have a problem with comments under graph.
I'm trying to write comments below my graph that indicates what each line means.
Something like:
------------- parents salary
..................... number of kids

The problem is that I can't get dashed-dotted and dotted lines.

Below are my commends.
Any help will be appreciated!

You can use \draw[dashed] or \draw[dotted] or \draw[densely dashed], and nodes, or the quotes library syntax. Perhaps show a complete drawing, otherwise we cannot test anything.

Sure, I have attached.
As can be seen I have tried to improvise but its not going well.

I would use pgfplots for the whole image. Though the pgfplots author Christian Feuersänger provided a way to use a pgfplots legend in a TikZ picture.

Btw. I would use \max for an upright max.

Thanks,
Is there a possibility to get the same result without the box being seen?

[Stefan Kottwitz]

Sure, insert draw=none here in the legend style:

Thanks again.
It works fine when it runs by itself but not when I add it to my article.
Any suggestions why?

[Stefan Kottwitz]

Only if you would post the error message, possibly the whole preamble of your article. Otherwise I cannot know what happens in that other document.

Stefan

Obviously, thanks again!
