Canvas charts

• Installing and implementing RGraph
  The installation pages detail how you go about implementing RGraph on your website. They have lots of useful information such as browser support for RGraph, getting started with RGraph and getting the best performance from 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.
  
  
• Features documentation
  The majority of the features of RGraph are documented here. There are lots of features that are available to you such as tooltips, events, adjusting and annotation.
  
  
• Index of HOWTO guides
  HOWTO guides offer straightforward guides for accomplishing specific tasks. There are about 50+ guides that are available in total.

  Each guide attempts to take you through the steps that are necessary to accomplish the task. They also provide the source code that's used as well.
  
  

• The drawing API
  The drawing API offers you a way to add shapes and images to your canvas tags that support events and tooltips. There are basic shapes available to you (rectangles and circles, for example) and also chart elements like axes and background objects. This example has a few extra Y axes added.
  
  
• Browse the RGraph GitHub repository
  Do you want to browse the RGraph source code or watch the development? RGraph is now available via a GitHub repository and you should feel free to star the project so that you can easily keep an eye on it!
  
  
• Miscellaneous documentation
  Various documentation that doesn't fit elsewhere. This is worth reading as it lists several small things that you may or may not come across and which have answers that aren't immediately obvious.
  
  
• An HTML5 canvas reference
