For everyone else who is having issues to format the x-axis in a specific
timezone, I found a solution as a workaround:
Use your own formatter function by using the way how it's written in the
documentation.
```
...
axisLabel: {
formatter: (value) => {
return this.getFormattedUnitFromValue(value);
}
}
...
```
Finally extract the functionality of
https://github.com/apache/echarts/blob/master/src/util/time.ts#L223C3-L223C31
to your needs, like the following:
```
private getFormattedUnitFromValue(
value: number | string | Date,
): string {
// The following code is kind of a copy to distinquish which format
should be used
const isUTC: boolean = this.useUtc;
const date: Date = new Date(value);
const M: number = (isUTC ? date.getUTCMonth() : date.getMonth()) + 1;
const d: number = isUTC ? date.getUTCDate() : date.getDate();
const h: number = isUTC ? date.getUTCHours() : date.getHours();
const m: number = isUTC ? date.getUTCMinutes() : date.getMinutes();
const s: number = isUTC ? date.getUTCSeconds() : date.getSeconds();
const S: number = isUTC ? date.getUTCMilliseconds() :
date.getMilliseconds();
const isSecond: boolean = S === 0;
const isMinute: boolean = isSecond && s === 0;
const isHour: boolean = isMinute && m === 0;
const isDay: boolean = isHour && h === 0;
const isMonth: boolean = isDay && d === 1;
const isYear: boolean = isMonth && M === 1;
// Here you can put your own format logic
const is24hFormat: boolean = !this.myTimeFormat.includes("am");
let format: string;
if (isYear) {
format = "yyyy";
} else if (isMonth) {
format = "MMM";
} else if (isDay) {
format = "d. MMM";
} else if (isHour) {
format = is24hFormat ? "hh:mm a\nd. MMM" : "HH:mm\nd. MMM";
} else if (isMinute) {
format = is24hFormat ? "hh:mm:ss a\nd. MMM" : "HH:mm\nd. MMM";
} else if (isSecond) {
format = is24hFormat ? "hh:mm:ss a\nd. MMM" : "HH:mm:ss\nd. MMM";
} else {
format = is24hFormat ? "hh:mm:ss SSS a\nd. MMM" : "HH:mm:ss SSS\nd.
MMM";
}
// Finally, you can use your logic to handle specific timezones
return this.dateTimePipe.transform(date, format); // Angular example
with a custom datePipe
}
```
