DefaultFontName not used everywhere

asked Apr 6 in Question / help by GiVe

I noticed that in a timing diagram (https://plantuml.com/timing-diagram), the DefaultFontName is not applied to time constraints (i.e. the text above the arrow). Is there a way to change the font name and size for these elements?

Plantuml supports quite a few font name changes:

To help you better (I don't see the wrong font, might be my interpretation of the characters though):

  • Which version of plantuml are you using?
  • Please show what you got / where your problem lies.

Thanks Albert,

Yes I was aware of the skinparams and tried quite a few. I'd expect DefaultFontName to apply globally.

I am using the latest PyCharm PlantUML plugin.

This is an example (after rendering, the text over the arrows will not adopt the font):

@startuml

skinparam DefaultFontName Gill Sans MT
skinparam DefaultMonospacedFontName Gill Sans MT

robust "Web Browser" as WB
concise "Web User" as WU

WB is Initializing
WU is Absent

@WB
0 is idle
+200 is Processing
+100 is Waiting
WB@0 <-> @50 : 50 ms lag

@WU
0 is Waiting
+500 is ok
@200 <-> @+150 : 150 ms

I did some analysis on the problem (it is hard to spot when one is not that good in knowing what to look for). I generated, locally, a svg image and in here I see:

<text fill="#000000" font-family="Serif" font-size="14" lengthAdjust="spacingAndGlyphs" textLength="55" x="129" y="88.3105">50 ms lag</text>

...

<text fill="#000000" font-family="Serif" font-size="14" lengthAdjust="spacingAndGlyphs" textLength="42" x="260.5" y="165.3242">150 ms</text>

whilst other text lines look like:

<text fill="#000000" font-family="Gill Sans MT" font-size="18" lengthAdjust="spacingAndGlyphs" textLength="60" x="239" y="204.1387">Waiting</text>

so I do see a difference for the "m" and "n" indicating the problem.

Note that the problem also is present for the:

skinparam DefaultFontSize 18

I used: PlantUML version 1.2020.07beta7
