Range Area Charts

Range area charts plot two values on the Y axis for each data point and fill the area between. This is like the range bar and column charts that plot a range of two values for each data point. This new chart type is enabled by setting the chart type as 'Area' and then setting the upper and lower range values in the series binding.

Multiple Pie Chart Series

You can now use FlexPie to visualize more of your data in a single chart by creating multiple pie chart "series" using the same data source. It works by setting the binding property to a comma delimited string containing each field name you wish to visualize as a pie chart.

Custom Series Tooltips and ItemFormatter

We’ve added two new features for FlexChart that make it easier to customize specific series. The Series.tooltipContent property allows you to customize the tooltips and the Series.itemFormatter property allows you to customize the appearance of the data points in a specific series. Prior to this release, these properties were set at the control level, so they applied to all series in the chart.

By duplicating these properties at the series level, we’ve added more flexibility and customization options to charts with multiple series.
