Question

just like in subject. I read documentation from plotly but i did not found any helpfull information. Maybe someone know how to add title to each plot in PLOTLY JS ?

Answer 1

At the moment you can,t set the subplot title directly. But you can set subplot title using annotation text.

Hear is a example

    //Set annotations text in layout configuration
annotations: [{
        text: "First subplot",
          font: {
          size: 16,
           color: 'green',
        },
        showarrow: false,
        align: 'center',
        x: 0.13, //position in x domain
        y: 1, //position in y domain
        xref: 'paper',
        yref: 'paper',
      },
        {
          text: "Second subplot",
          font: {
          size: 16,
          color: 'orange',
        },
        showarrow: false,
        align: 'center',
        x: 0.9, //position in x domain
        y: 1,  // position in y domain
        xref: 'paper',
        yref: 'paper',
        }
      ]
