Some additional information. It turns out moving the IE page to my second monitor causes the zoom setting to increase. It seems that the zoom setting is the actual cause. If you go to you canvasjs gallery as I mentioned before and set the zoom to 125% or more in IE11 or Firefox, line style charts don’t render. Chrome seems to work OK.
Groovy. Thanks for the quick response. I also added markerType: “none” to keep the lines from getting lumpy.
Thanks again, great product.
