Update x-axis or autoscale when using slider or button

I am new to plotly (and to js). I have adapted that code (https://plot.ly/javascript/gapminder-example/) to my data but I cannot make the x-axis automatically update or autoscale when new data are selected with the slider (or even the button). Any way of easily sorting that out ? Many thanks.


Plotly.d3.csv('myData.csv', function (err, data) {
  // Create a lookup table to sort and regroup the columns of data,
  // initial by CatOrder, then by CatConc:
  var lookup = {};
  function getData(CatOrder, CatConc) {
    var byCatOrder, trace;
    if (!(byCatOrder = lookup[CatOrder])) {;
      byCatOrder = lookup[CatOrder] = {};
    }
	 // If a container for this CatOrder + CatConc doesn't exist yet,
	 // then create one:
    if (!(trace = byCatOrder[CatConc])) {
      trace = byCatOrder[CatConc] = {
        x: [],
        y: [],
        id: [],
        text: [],
        marker: {size: []}
      };
    }
    return trace;
  }

  // Go through each row, get the right trace, and append the data:
  for (var i = 0; i < data.length; i++) {
    var datum = data[i];
    var trace = getData(datum.CatOrder, datum.CatConc);
    trace.x.push(datum.tCatOrder);
    trace.y.push(datum.SubConc);
    trace.marker.size.push(50);
  }

  // Get the group names:
  var CatOrders = Object.keys(lookup);
  // In this case, every CatOrder includes every CatConc, so we
  // can just infer the CatConcs from the *initial* CatOrder:
  var initialCatOrder = lookup[CatOrders[0]];
  var CatConcs = Object.keys(initialCatOrder);

  // Create the main traces, one for each CatConc:
  var traces = [];
  for (i = 0; i < CatConcs.length; i++) {
    var data = initialCatOrder[CatConcs[i]];
	 // One small note. We're creating a single trace here, to which
	 // the frames will pass data for the different CatOrders. It's
	 // subtle, but to avoid data reference problems, we'll slice
	 // the arrays to ensure we never write any new data into our
	 // lookup table:
    traces.push({
      name: CatConcs[i],
      x: data.x.slice(),
      y: data.y.slice(),
      id: data.id.slice(),
      text: data.text.slice(),
      mode: 'markers',
      marker: {
        size: data.marker.size.slice(),
        sizemode: 'area',
        sizeref: 0
      }
    });
  }

  // Create a frame for each CatOrder. Frames are effectively just
  // traces, except they don't need to contain the *full* trace
  // definition (for example, appearance). The frames just need
  // the parts the traces that change (here, the data).
  var frames = [];
  for (i = 0; i < CatOrders.length; i++) 
  {
    frames.push({
      name: CatOrders[i],
      data: CatConcs.map(function (CatConc) {
        return getData(CatOrders[i], CatConc);
      })
    })
  }

  // Now create slider steps, one for each frame. The slider
  // executes a plotly.js API command (here, Plotly.animate).
  // In this example, we'll animate to one of the named frames
  // created in the above loop.
  var sliderSteps = [];
  for (i = 0; i < CatOrders.length; i++) {
    sliderSteps.push({
      method: 'animate',
      label: CatOrders[i],
      args: [[CatOrders[i]], {
        mode: 'immediate',
        transition: {duration: 300},
        frame: {duration: 300, redraw: false},
      }]
    });
  }

  var layout = {
    xaxis: {
      //range: [0, 10000],
      autorange: true,
      title: 't.[A]^(catOrder)',

	 // passing `[null]`, which indicates we'd like to interrupt any
