Please add this option     Boolean - Whether the scale should start at zero  or an order of magnitude down from the lowest value scaleBeginAtZero   true     Reference  Chart js   N B  The original solution I posted was for Highcharts  if you are not using Highcharts then please remove the tag to avoid confusion

If you need use it as a default configuration  just place min  0 inside the node defaults scale ticks  as follows   defaults      global           scale                ticks    min  0             Reference  https   www chartjs org docs latest axes

For Chart js 2    the option for the scale to begin at zero is listed under the configuration options of the linear scale  This is used for numerical data  which should most probably be the case for your y-axis  So  you need to use this   options        scales            yAxes                 ticks                    beginAtZero  true                                    A sample line chart is also available here where the option is used for the y-axis  If your numerical data is on the x-axis  use xAxes instead of yAxes  Note that an array  and plural  is used for yAxes  or xAxes   because you may as well have multiple axes
