Wrong line annotation - OLCH chart

[antoniorg10]

Hello, i'm trying to draw a line correctly but my xValue and yValue not displayed in the correct position of the chart.

I set my first XValue in February 1 but the line appears on Jan 21, the same applies in the YValue

Thanks for reporting!

It looks like the default values (center/middle) for anchorX and anchorY cause that offset. When setting strictly left and top the line will work fine, check: http://jsfiddle.net/mtjemebv/5/

Internal note:
Probably we should change default values, to the ones listed above, in this line - it is very confusing, I think.
