Canvas charts

Documentation and information about the features for canvas charts that are available in RGraph. If you want guidance on setting up RGraph look at the Implementing RGraph pages And if you're looking for information about what RGraph can do then look at the Features pages.

• Installing and implementing RGraph

• Available types & option references
  RGraph supports twenty-one different types of charts and many can be made to look significantly different through the use of the properties. An example of this is the fan chart in the download archive that can be created with multiple Line objects and which can represent growing uncertainty in a predicted set of values.
