Dynamically create DateTimeAxis QML chart SplineSeries

Question

I used to append using

 splineseries->append(i.key().toMSecsSinceEpoch(),i.value());

But x axis getting same value repeated .

The problem is that the format is extensive and they are overlapping, could provide a [mcve] and show a picture of what you want to get to help you. — eyllanesc, Aug 06 '18 at 09:23
Also I do not see any data and with a well known date of the year 70, so it makes me suppose that you are not adding the data correctly, or the dates you have are null. — eyllanesc, Aug 06 '18 at 09:25
Its a map. I is the iterator. Data and epoch is getting correctly printed on console. — Masthan, Aug 06 '18 at 09:28
I doubt it, if you do not provide a [mcve] I will continue to doubt it so the results contradict you. — eyllanesc, Aug 06 '18 at 09:28
I dont know why 1970 came. Actually I used 2018-05-23 and related dates — Masthan, Aug 06 '18 at 09:28
read http://doc.qt.io/qt-5/qdatetime.html#details : *A datetime can also be set using the setTime_t() function that takes a POSIX-standard "number of seconds since 00:00:00 on January 1, 1970" value* — eyllanesc, Aug 06 '18 at 09:31
We have to initialize datetime axis with proper min and max . Otherwise it will be set to base 1970 — Masthan, Aug 06 '18 at 10:45
You see, I assume that they had placed a range at the time, for me your question is of poor quality because it does not give us the necessary elements to solve it. Do you want us to guess? — eyllanesc, Aug 06 '18 at 10:52

splineseries->append(i.key().toMSecsSinceEpoch(),i.value());

will work . But We have set min and max values for DateTimeaxis like

Xaxis->setMin(QDateTime(QDate(2018,01,01),QTime(01,00,00)));
Xaxis->setMax(QDateTime(QDate(2050,01,03),QTime(12,00,00)));
