Main Question

I want to change all properties of certain TikZ elements in the style of TikZ’ append. However, unlike its name suggests, append provides only defaults. By contrast, I wish to override any detailed settings made in the specific TiKZ commands. Is there any general way to do this?

I noticed that the handle every axis plot post in PGF Plots does something similar, but I lack the knowledge to translate its source to my problem.


    \tikzset{every path/.append style={dashed,draw=red}}
    \draw[dotted]        (0,0) -- (1,1);
    \draw[dotted,dashed] (0,1) -- (1,0);

Output of example code

Here, the dotted argument of the \draw command superseeds the general style dashed by append. Only literally appending the dashed property (second line) works.

I am looking for something to write at the beginning of the tikzpicture looking like:

\tikzset{every path/.override style={dashed}}

and causing all lines in the above to be dashed. For me it would suffice to explicitly override the dotted property here.

Actual Application

I have a plot file generated with tikzplotlib (using add_axis_environment=False) featuring dashed lines and I want to change the dash pattern without manually changing the file. I know I could programmatically modify the plot file, but then my format specifications would not be bundled in one place (my TEX file) any more.

  • Append appends to every path, i.e. to the defaults of that key. But the every path key is executed before any of the settings for a single path apply (this is a usual pattern to allow local overrides for global configs). So you are setting the wrong key… – TeXnician Jul 16 '19 at 14:25

  • @TeXnician: Do you know in advance which effects you want to nullify? – Yes, see the last section. – Wrzlprmft Jul 16 '19 at 14:31
  • Well, it was more a question which effect you want to nullify in the sense of "is it a specific set of keys or may it be arbitrary"? In the first case one could locally undeclare these keys. If it's the last one we'll have to wait for a TikZpert. – TeXnician Jul 16 '19 at 14:34
  • @TeXnician: I am not fully sure I got you right, but please see my edit. – Wrzlprmft Jul 16 '19 at 14:40

If you just want to "nullify" the effect of a style, you can redefine it:
