If I reduce the size of the created figure, I need to increase the text size of PlantUML.
The following statement inside @startuml leads to smaller text but increases the rectangles.
skinparam defaultFontSize 25
Using a size like 5 does the opposite. It changes the font size to a bigger font than normal but the rectangles are decreasing and the text doesn't fit anymore to the boxes.
skinparam defaultFontSize 5
if (Number) is ( < 5 ) then
Thanx in advance
