I currently have both the chartfx 6.2 and new chartfx 7 installed locally on my development box. I had to make changes to an old asp.net 1.0 application that uses the chartfx 6.2 dll. Everything works fine locally until I moved my compiled code to our stage server. All that comes up is a grey box, the expected functionality when you right click is there , the chart is just not rendered for some reason. If i set the html tag to image , it shows up. file:///C:/Documents%20and%20Settings/Rich/Desktop/chfx62.jpg
