I have these options on my code and I'm using chart js

 options: {
                scales: {
                  x: {  
                     min: 1,
                      ticks: {
                          stepSize: 0.3
                      }
                   },
                  y: {  
                  min: 1,
                    ticks: {
                        stepSize: 0.1
                    }
                   }
                    },
}

When the chart renders, the first step size on the X axis is 1.2 instead of 1.3... but the rest of them step by 3.. so for example on the X axis I have 1.0, 1.2, 1.5, 1.8, 2.1.. But I need 1.0, 1.3, 1.6... I have read the doc of chart js and that's the way to change the ticks, but is not working with those values... Does anyone know why? Is it an issue unresolved by Chart Js?

Thank you
