javascript - highcharts get all of the minimum points of the chart -

i have 10 series in chart.

1) how can find minimum point of series?

2) how can set chart's starting point red line?

here fiddle:

xaxis: {                     gridlinewidth:'1',     gridlinedashstyle:'shortdot',     tickinterval:1 }, yaxis: {                     gridlinedashstyle:'shortdot',                               }, tooltip: {     shared: true,     crosshairs:[{         width:1,         color: 'black'     }] }, credits: {     enabled: false }, plotoptions: {     area: {         fillopacity: 0.3,         pointstart:1,     }                 } 

1) can use loop on each series / , point , return correct value.
