Sans serif font for Gantt diagram

0 votes
asked Aug 18 in Wanted features by Emmanuel
Hello !

Would it be possible to change the currently used font for Gantt diagrams to a sans serif one, like Arial or DejaVu Sans? Since Gantt diagrams are mainly to be shown on screen, and since PlantUML images are low DPI, serif font as used now reduces readability.

Thanks !

With: java -Djava.awt.headless=true -jar plantuml.jar  -language

you get (o.a.) all recognized skin parameters, here you can search for all the FontNames that can be changed (I count 84 in PlantUML version 1.2020.16beta8), though it looks like there is not direct one general one for Gantt charts.

Thanks for your answer that pointed me to the skinparam directive.

But the Gantt diagram doesn't seem to allow skinparam. You can look at this http://www.plantuml.com/plantuml/umla/SoWkIImgIK_CAodXAixEp2j8B4hCLKX9JKiipIbnoyyhyKlCJLNmICqfIot9J4xaYWv9BCwELSX9B2ufLZ0oK4X9h2pcSaZDIm4R0G00 where I'm using the specific starting command.

Or this where I use the @startuml generic one: http://www.plantuml.com/plantuml/umla/SoWkIImgAStDuIhEpimhI2nAp5L8IKrBBCqfSSlFA_5Bp4rLy4ZDAKijoKnEv8eEIIpEZbN8IImkALOmCb18IQmivd98pKi16W00

In either case, there is a syntax error which disallows me to change any styling parameters. Perhaps am I doing wrong ?

With last beta http://beta.plantuml.net/plantuml.jar, you can now have

@startuml
<style>
ganttDiagram {
    task {
        FontName Helvetica
        FontColor red
        FontSize 18
        FontStyle bold
        BackGroundColor blue
        LineColor yellow
    }
    milestone {
        FontColor blue
        FontSize 25
        FontStyle italic
        BackGroundColor yellow
        LineColor red
    }
}
</style>
[Task] lasts 20 days
[M1] happens on 5 days after [Task]'s end
