Possibility of a X/Y Axis Label for the most recent value?

[EthanBlank-Git]

First off, thank you for this library, it is by far the best charting library I have used so far, you are amazing!!

Just was wondering if there is any thoughts about an X/Y axis label that would display the current value of the last data point. Similar to how Trading View and other stock market charts have this:

Hi and thanks!

Yes it will be implemented, but it is not ready yet, we can track this at #490.

Hello @EBTheKidd were you able to implement this based on the enhancement from #490? If so could you share your approach?

Looking for the same capability: #883

Kind regards

I was able to get it working, with mixed results:

It works as described, although my program appeared to crash quite frequently while using it. I believe it is because my chart is constantly updating, although I am not 100% sure. Here is my code (taken from the sample provided in the documentation)

Being that it continuously crashes the application (only while trying to use the crosshair), I decided to omit it from my releases until I can track down the issue
