How to control box size?

Question

Here is my uml code:

```

@startuml

start

: Input;

: Initialize;

repeat

    : Randomly select a sample pair;

    : Forward propagation;

    : Computing gradient;

    : Back propagation;

    : Caculate <latex>J_t</latex>;

repeat while (convergence?)

: Output;

stop

@enduml

 

```

which produces:

 

 

the width of the box differs, and look not so good, how could I control it?

And the math equation seems do not work well with text.

And if I could somehow add text to the arrow from "convergence?" to loop start, it will be great.

The only way I know to have same size is using whitespace to force it.

Answer 1

it can be set with style

<style>
activity {
  MinimumWidth 200
}
</style>

Hi all,

Good catch...

And just for the record:

>the width of the box differs, and look not so good, how could I control it?

Use style as mentioned by K.

>And the math equation seems do not work well with text.

See similar remark/request here:

>And if I could somehow add text to the arrow from "convergence?" to loop start, it will be great.

Use backward, see: 

• Please provide a way to add an action to the repeat loop start instead of a condition - PlantUML Q&A
