KLA Tracker bug fixes

2019-Oct-8

The KLA tracker has been pretty stable, but a bug in the graphics bothered me. When the line plot option is used the lines don't appear to be smooth and continuous. You can see that right from the first example screen shot I posted, reproduced below:

If we set it to plot a point every 60 seconds using the line plot then its clear what is going on, as shown below. Doh! The lines are vertical and don't join up. So there is a bug in the code.

If we fix the drawing routine then we get a much smoother plot, as show in the image below. This is now in Version 1.01d and can be downloaded from the KlaTrack home page

Cool application! I've been using KLA Track since the first release!

Just one thing to mention: many satellite names are overlaped on the line plot. Maybe the name/elevation can be displaced to one side but I guess that this can be tricky to achieve when two or more satellites are close.

Keep up the good work!

Nice suggestion @Limaunion.  I'll consider trying to avoid overlapping lines and 
labels in a future release.
