Problem with scaling Y axis

[NataliaKrzykala]

Hello,
I'm using YCharts for simple project containing a chart for temperature measurements depending on the date they were taken. I have a problem with scaling Y axis according to dynamically changing dataset. For example:

• when I set min and max values for Y (fe. 33 and 43) and try to scale my dataset to it, the smallest and the bigest value in the dataset still end up at 33 and 43. I was wondering if it is possible to plot a chart not adjusted to the dataset min max values (or if I'm doing something wrong). Example of a problem:
  

• when I do not set strict min and max values for Y (but get them from dataset) and set a strict numer of steps I end up whith multiple labels repeated (data seems to be scaled properly and every value is where it's supposted to be). I was wondering if there's a way to ommit displaying repeated labels. Example of a problem:
  

Additionaly, why does the lowest horizontal grid line stop at the last value and other don't?

I also have a problem with first X label being cut off but I saw someone else mention it in an issue and for all I know it hasn't been solved yet, right?
