I currently use dygraphs to create a stacked step plot graph. dygraphs, however, has its limitations when it comes to stacking positive and negative numbers. I have spent a lot of time researching on this problem and I don't believe it can be solved using dygraphs. That is why I am now ready to try alternative plotting methods.
In the attached you will find an R Script that draws the dygraph graph. You need to install the three R packages and then source the R script. The graph will then be displayed. I have also attached a word document where you see how I would like the graph the look. Dygraph has a lot of very nice features (range selector, zoom on graph, hover on mouse-over, the ability to check and uncheck series, etc.) and I want to keep all of these functionalities even if an alternative to dygraph is used.
If the freelancer solves this problem here, there will be more work to come.
