Customize legend title text

[Mengesh]

Would it make sense to introduce another global variable i.e. LEGEND_TITLE_TEXT that would default to Legend but also let the user specify it's own title?

[kirchsth]

Yes, would be a good idea. It looks like I have overseen it ;-)

I think it would be a small extension.

• line ~57 :add !$LEGEND_TITLE_TEXT?= "Legend"
• line ~2131: replace **Legend** with **$LEGEND_TITLE_TEXT ** (space after $LEGEND_TITLE_TEXT is important that we don't get an error if $LEGEND_TITLE is set with an empty value)

' Labels
' ##################################

!$LEGEND_TITLE_TEXT?= "Legend"
!$LEGEND_SHADOW_TEXT ?= "shadow"
....
<$colorWithHash(transparent),$colorWithHash(transparent)>|<color:$LEGEND_TITLE_COLOR>**$LEGEND_TITLE_TEXT **</color> |

and then it can be used like in (the updated version of) ./percy/TestLegend.puml

@startuml

!$LEGEND_TITLE_TEXT = "Updated legend title"
' !$LEGEND_TITLE_TEXT = ""

!include https://raw.githubusercontent.com/plantuml-stdlib/C4-PlantUML/master/C4_Component.puml
...

I will try to fix it next weekend.

Hi @Mengesh,

I have a new implementation in MR #366, can you please check it

Thank you and best regards
Helmut

`UpdateLegendTitle(newTitle)

Based on discussion #363 a new issues was created (#364) and a new UpdateLegendTitle(newTitle) call is added.
This call changes the legen title similar to the other Update....(..., ?legendText, ...) calls which change the legend texts of tags.

Ex. following code:

@startuml
!include https://raw.githubusercontent.com/kirchsth/C4-PlantUML/extended/C4_Container.puml

' NEW CALL UpdateLegendTitle
UpdateLegendTitle("Updated legend title")

Person(admin, "Administrator")
System_Boundary(c1, 'Sample') {
    Container(web_app, "Web Application")
}
System(twitter, "Twitter")

SHOW_LEGEND()
@enduml

produces following diagram:
