Monthly X-Axis labels (corresponding values) in my LineChart are not at the right position

Hi guys!

I want to build a Chart for my Swift iOS App where I can track when I lifted Y-amounts of weights in the gym. Therefore I neet dates on the X-Axis and some weight-values on the Y-Axis. I use timestamps for the X-Axis. On the X-Axis Labels I don't want to see the exact dates when I trained but rather the rough span of the months. With the formatter I made it that the months show up on the labels, but the labels/the corresponding vertical line are not at the right position.

So my issue is, that the months don't start and end at the right time. How can I manually change the values (and with that the corresponding position) for the months.

For simplification purposes I attached a picture. at the top as X-Axis labels you see values beginning from 1542000000 with a fixed space of 3000000 between them. With the formatter I made it that here are normally the right months. To make it clear I put the line-values at the beginning and at the end of the months. You see for past months the difference gets bigger. With some tweaking of the setLabelCount I make it to look right for a current set of data but when the data changes it will become wrong again.

Are these numbers set in the entries? How can I change/define these?

Since it is my first post here and I am still new at coding, I apologize in advance for any lack of knowledge.

please take a look at the ChartsDemo and maybe ask on stack overflow. IMO you shouldn't use timeInterval, just 1,2,3,4 and format it to month.
