WjFlexChart Class

AngularJS directive for the FlexChart control.

Use the wj-flex-chart directive to add charts to your AngularJS applications. Note that directive and parameter names must be formatted using lower-case letters with dashes instead of camel case. For example:

<p>Here is a FlexChart control:</p>
<wj-flex-chart
  style="height:300px"
  items-source="data"
  binding-x="country">
  <wj-flex-chart-axis
    wj-property="axisY"
    major-unit="5000">
  </wj-flex-chart-axis>
  <wj-flex-chart-series
    binding="sales"
    name="Sales">
  </wj-flex-chart-series>
  <wj-flex-chart-series
    binding="expenses"
    name="Expenses">
  </wj-flex-chart-series>
  <wj-flex-chart-series
    binding="downloads"
    name="Downloads"
    chart-type="LineSymbols">
  </wj-flex-chart-series>
</wj-flex-chart>

The example below creates a FlexChart control and binds it to a 'data' array exposed by the controller. The chart has three series objects, each corresponding to a property in the objects contained in the source array. The last series in the example uses the 'chart-type' attribute to override the default chart type used for the other series objects.
