Overview of this book

Visualforce, in conjunction with Apex, makes it easy to develop sophisticated, custom UIs for Force.com desktop and mobile apps without having to write thousands of lines of code and markup. The "Dynamic Binding" feature of Visualforce lets you develop generic Visualforce pages to display information related to the records without necessarily knowing which data fields to show. This is accomplished through a formula-like syntax, which makes it simple to manage even a complex hierarchy of records. "Visualforce Development Cookbook" provides solutions for a variety of challenges faced by Salesforce developers and demonstrates how easy it is to build rich, interactive pages using Visualforce. Whether you are looking to make a minor addition to the standard page functionality or override it completely, this book will provide you with the required help throughout. "Visualforce Development Cookbook" starts with explaining the simple utilities and builds up to advanced techniques for data visualization and reuse of functionality. This book contains recipes that cover various topics like creating multiple records from a single page, visualizing data as charts, using JavaScript to enhance client-side functionality, building a public website and making data available to a mobile device. "Visualforce Development Cookbook" provides lots of practical examples to enhance and extend the Salesforce user interface.

Adding a third axis


Plotting multiple series on a single graph can be problematic if the values of the two series vary widely. For example, if the total value of won opportunities were plotted against the record count of won opportunities, the total value number would be likely to be several hundred thousand times the record count number. Plotting these on a single chart would result in the record count plot being as close to zero as to be indistinguishable from zero.

The solution to this problem is to display a third axis. The axis is scaled appropriately to the data set that is plotted against it.

In this recipe we will create a Visualforce page containing a chart that displays the total value of the won and lost opportunities per month for the last year. The won/lost information is displayed as a stacked bar chart. The chart also displays a line series chart where each point on the line series is the number of opportunities that were won/lost in that month. As the number of opportunities...
