Is there any possibility to draw backward interaction like A<---B instead of response A<- - - B ?

Sorry for replying late. Please if possible use the chat feature on https://www.zenuml.com to get quick response. I often forget checking gist notifications. I got a lot of notification of other projects I am following :)

I am not quite sure what you means here. The backward interaction is a dashed boarder and controlled by:

    border-bottom-width: 2px;
    border-bottom-style: dashed;

Do you mean the space between dashes are too wide?

If you are using the Chrome extension, you can make it dotted by putting the following in the CSS editor:

.message[data-v-72ecb252] {
    position: absolute;
    width: calc(100% - 14px);
    border-bottom-width: 2px;
    border-bottom-style: dotted;
}

Not sure if it works for your usage.
