[Solved]-Highcharts - How can I remove starting and ending padding from area chart-Highcharts

for this no need to go with categories or the datetime type of x-axis just change the data

in this format

data: [,[x1,y1],[x2,y2],[x3,y3],[x4,y4],[x5,y5]]

ex:

 data: [[1750,106], [1800,107], [1850,111], [1900,133], [1950,221], [1999,767], [2050,1766]]

hope this will be useful
