# Adjust labels of diagrams after exporting from Inkscape

SE,

I am not experienced at TikZ at all, so I decided to use Inkscape. Using Inkscape, I recreated this diagram (p. 13) In Inkscape, it looks pretty good, with the labels (i.e. Eluent and Probe) nicely moved from the part.

However, if I save it as a PDF, following this workflow, I get the following (yellow boxes added to show issues):

In some cases (e.g. Trennsäule), the text isn't in conflict with the image. However, in the outlined cases, it is.

Is there a way to adjust the labels manually, if you have the .pdf_tex?

.pdf_tex:

From your pdf_tex I see a lot of \makebox(0,0)[lt] which means you chose left-alignment for all your text elements. This brings you into trouble when the font size in Inkscape doesn't match the font size in LaTeX. So there are two ways:
• Adjust the font size by adding one of \small, footnotesize, etc. before your input (perhaps in a group, {\small\input{drawing.pdf_tex}}) such that the text takes roughly the same space as in Inkscape and the overlays vanish.
• The export to PDF+TeX respects the horizontal alignment chosen in Inkscape. As an example, changing "Probeschleife" to right-aligned in Inkscape (the text there will still be in the same position) results in a \makebox(0,0)[rt], and thus the text will not overlay with the drawings to the right even if the text is larger than in Inkscape.
So, my advice is: In Inkscape, use left-alignment for labels right of the drawings, right-alignment for labels left of the drawings, and center-alignment for labels below/above the drawings; and then experiment with different font sizes right in front of the \input statement.
