use following option hide 0 (baseline) 

baselinecolor: 'transparent'

see following working snippet... 

google.charts.load('current', {'packages':['corechart', 'line']});  google.charts.setonloadcallback(drawchart);    function drawchart() {    var data = new google.visualization.datatable();    data.addcolumn('date', 'date');    data.addcolumn('number', 'population');    data.addrows([      [new date(1400, 1, 1),  -44],      [new date(1500, 1, 1),  33],      [new date(1600, 1, 1),  88],      [new date(1700, 1, 1),  100],      [new date(1750, 1, 1),  200]    ]);      var linearoptions = {      baselinecolor: 'transparent',      title: 'world population since 1400 a.d. in linear scale',      legend: 'none',      width: 450,      height: 500,      haxis: {        title: 'date'      },      vaxis: {        title: 'population (millions)',        ticks: [-100, 100]      }    };        var linearchart = new google.visualization.linechart(document.getelementbyid('linear_div'));    linearchart.draw(data, linearoptions);  }

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
