  I have a problem with my Tooltip
  Example: I have 3 visible series and 1 invisible.
  Can I only show 3 tooltip for 3 visible series?
  I don’t want to show all 4 series in this case?

  You can hide the information related to hidden dataseries by setting toolTipContent of that particular dataseries to null. Please find the code-snippet below.

  itemclick : function(e) {
    var content;
    if (typeof(e.dataSeries.visible) === "undefined" || e.dataSeries.visible) {
      e.dataSeries.visible = false;
      content = e.chart.data[e.dataSeriesIndex].toolTipContent;
      e.dataSeries.toolTipContent = null;
    }
    else {
      e.dataSeries.visible = true;
      e.dataSeries.toolTipContent = content;
    }
    chart.render();
  }

  Please take a look at this JSFiddle for complete code.
