I'd like to use Dygraphs for a web project, but I need to graph my lines in a "vertical" fashion- meaning- what is normally the X axis (horizontally, along the bottom), I need to be graphed from top to bottom (with the x axis along the left edge).
I've looked at several graphing libraries for this and none seem to support it. I recently discovered Dygraphs so I'm hoping it might have this feature.
While vertical charts are not supported out of the box, it is possible to achieve this effect using CSS transformations. Basically, you rotate the <div> that contains the chart by 90 degrees and undo that transformation for the labels.
One dygraphs user was able to get this work. See this demo.
