Echarts.js on Angular 10 and these are my toltip options :
tooltip: {
show: true,
trigger: 'axis',
axisPointer: {
type: 'line',
lineStyle: {
color: eTheme.tooltipLineColor,
width: eTheme.tooltipLineWidth,
},
},
textStyle: {
color: eTheme.tooltipTextColor,
fontSize: 20,
fontWeight: eTheme.tooltipFontWeight,
},
position: 'top',
backgroundColor: eTheme.tooltipBg,
borderColor: eTheme.tooltipBorderColor,
borderWidth: 1,
extraCssText: eTheme.tooltipExtraCss,
formatter : (params) => {
return Math.round(parseInt(params[0].value, 10));
},
},
The problems is that with formatter my tooltip is not showing , when i delete formatter - everything is fine and tooltip is showing again.
What is wrong with formatter ?
