Chapter 4. Upgraded Charts

Ext JS 4 has vastly improved on charts and drawing packages. Ext JS 3 introduced some charts, but they still had many features to improve on, starting with the fact that Ext JS 3 used Flash to render the charts. As Ext JS is a JavaScript framework, the chart package has been rewritten, and now, the charts no longer need Flash to be rendered. Ext JS 4 also introduces some new chart series, such as, Radar, Scatter, and Gauge.

In this chapter, we will cover:

  • The difference between Ext JS 3 and Ext JS 4 charts
  • Ext draw package features
  • An Ext chart package overview
  • How to configure Legends
  • How to use Axis
  • Chart Series
  • Customize a Chart Theme

We will also learn how to implement:

  • Pie Charts
  • Area Charts
  • Column/Bar Charts
  • Line Charts
  • Radar ...
