Chart not being responsive -react-plotly.js

Question

I have implemented a scatterplot using react-plotly.js I would like the chart to re-size itself when the page layout changes. But currently, the layout of the chart doesn't change by itself. If I explicitly perform some function on the chart which forces the chart to redraw itself then only the chart width changes.

I applied useResizeHandler property and have set autosize to true. But that doesn't make any difference either.

<Plot
   useResizeHandler
   style={{ width: '100%' }}
   data={chartData}
   onClick={(data) => this.handlePlotClick(data)}
   type={'scatter'}
   layout={this.layout} />

 const layout = {
      autosize: true,
      dragmode: true,
      margin: {
        l: 5,
        r: 5,
        t: 10,
        b: 10,
        pad: 0,
        autoexpand: true
      },
      hovermode: 'closest',
      hoverlabel: {
        bgcolor: 'rgba(0,0,0,1)',
        bordercolor: 'rgba(200,200,200,1)'
      },
      height: '650',
      yaxis: {
        visible: false
      },
      xaxis: {
        autorange: false,
        showline: true,
        fixedrange: false, // true disables range selection on main graph
        rangeslider: {
          range: this.state.sliderRange,
          visible: true,
          borderwidth: 1,
          bordercolor: '#000'
        }
      }
    };
  }

As you can see in the screenshot above, the div.svg-container has same width as the main-svg. But it still leaves white space on the right. I am unable to debug why it would behave that way. If I explicitly perform zoom on the chart that will redraw the plot then it will behave correctly. But I would like it to automatically resize when the page layout changes.

Answer 1

I was stuck on this problem too. Try window.dispatchEvent(new Event('resize')) from http://codrate.com/questions/how-can-trigger-the-window-resize-event-manually-in-javascript

I was calling resizeHandler when my chart is resized by dragging.

resizeHandler = () => {
    this.child.resizeHandler();
    window.dispatchEvent(new Event('resize'));
}

The charts always autoscales when the chart is resized, so I basically trigger the window resize when my chart size is changed. So for you, when you detect the page layout changes you can trigger the window resize.
