Absolute Y Axis

[jasonmcdermott]

I like having the option to auto-scale the Y axis for the graph, but I'd also like to be able to simply show absolute values. I'm currently hacking around this by auto-appending a value at the upper & lower range of my scale (40 & 180), so the graph auto scales between these values.

It would be great to have an option to set the scale to a range of values, on init (perhaps allowing for this to be set again later), rather than constantly autoscaling the graph.

Hi @jasonmcdermott,
This is an interesting feature. I just pushed a new commit (31f1b6e) on the feature branch that offers a new BOOL property that let you set the points on the Y-axis with absolute values.

The property is autoScaleYAxis. Its default value is YES.

self.myGraph.autoScaleYAxis = NO;

If you could give it a try with absolute values (by setting it to NO) and report back to me that would be great!
Thank you for the idea!

Sorry, Boris - I've been pretty busy lately. I'll give this a try today, will let you know how I get on.
Thanks, loving this lib!

Hi Boris, it works very well. Is there a way to set the upper & lower values of the graph manually? It seems like it's auto-assigned once only (in ViewDidLoad) and never again. It'd be useful if I could set the thresholds myself (e.g. between 40-200).

Hi @jasonmcdermott,
Great! I'm glad it works.
It would be good to be able to set the upper and lower values manually. It shouldn't be too much work. I'll give it a try next time I have time to spend on the library.
Thanks for your input!
