Time Chart for every second

[khailenkomaksym]

I want to create dynamic Line Time chart for every second. Because class Entry has X parameter of type float, so when we put milliseconds (type long) there is loss of information by cast from long to float. And some milliseconds will be equal to the same value, so the graph vertical lines appear. How to solve a problem? Class Entry not support long argument.

I have the same problem. The float precision is useless for plotting values with timestamps in epoch time. All sorts of awful things are happening.

Who did solve this problem?

@alegch
I had implemented one work around say I have 5 points [1507728180489, 1507728195797, 1507728203071, 1507728211324, 1507728218311]in sorted order.
take very first point as main point then while adding to entry minus this value then add so here.
long reference = 1507728180489L;
new Entry (0, 10);
new Entry (15308, 20) // 1507728195797 - reference
like that you add
then override YAxisFormatter and what ever value you get there add this reference long value

You can subtract a large number from all timestamps when you are converting them to Float, and add them back when you are reading the data

If you're using a unix timestamp, the problem is when it gets converted to Float, it loses precision, so lots of timestamps that actually represent different times end up being rounded and represented as the same x value. See #2891

Thanks @jackguo709 , this was my solution. Not elegant but working :)
