How to deal with the smaller value of echarts Map Thermal Map

now we need to show the thermal situation according to the data. My interval is 0,100, but why can"t a value of 0.12, which is less than 1, be shown on the map?
visualMap: {

type: "piecewise",
show: true,
precision:2,
min:0,
pieces: [
    {gt: 100},
    {gt: 10, lte: 100},
    {gt: 1, lte: 10},
    {lte: 1}
],
inRange: {
    color: ["-sharp0047BC","-sharp2AA917","-sharpECDF00","-sharpF71C1C"]
},
textStyle: {
    color: "-sharpfff"
}

},
