I am trying to create chart horizontally & vertically big size. For example it has got more than 100 nodes and each has got more subnodes. I want to print those chart in the end. sometimes a4 size (landscape) some times in a big plotter print outs. Already i gone through below link.
If you do not want to print on multiple pages, you can specify the size option which will cause the rendering to automatically scale to fit the given Size. Choose a size that is appropriate for your printer.
Please read GoJS Making SVG -- Northwoods Software. If you are going to print a large area, I recommend rendering to SVG rather than to a bitmap image, due to the memory requirements of bitmaps when trying to get good resolution.
