Missing Circles

[Joe Keohan]

I've created the following dual line chart which also adds corresponding circles to the display that actual event along with a tooltip.  The issue that I'm having is that the the "Run" line isn't displaying the first 2 circles.  I've added some console log data on lines 156 & 160 that corresponds to the attached picture.  It shows that the .data(data) has 10 objects however the first 2 circles aren't being defined in the .atttr("cy") When I examined the first 2 circles they show a cy value of -20.  I'm not sure why.  The line is using accurately plotting the the first two Run data points as I've tested changing those values.   If I do however remove the Walk data then those 2 dots are there.  Appreciate any help... 

The only other items I'd request an assist is how to add some space on the xAxis so as not to add a circle directly on the yAxis line.

My guess is that you're doing svg.selectAll("circle") and it's picking up two other circles in the document. If you add a class to the selector, it should work.

Thanks for taking a look Max...After some trial and error i noticed that removing the legend circles replaced the two missing ones in the line graph so that appears to be the issue.  Although I had originally added a class to the legend circles I'm not using the class to create the circles which I will work shortly.
