Editor's Note: So busy!

Another busy month (things don't seem to slow down, which is a good thing!), with new releases, betas, and a couple of cool new demos showing off Dundas's products in digital dashboards.

Let's get on with the newsletter!

Dashboard Insight

Dundas is proud to be a sponsor of Dashboard Insight, a new online magazine focused on everything related to the digital dashboard industry. We see Dashboard Insight as a comprehensive online destination designed to be the paramount resource for all decision makers in the industry. It offers informative articles, expert interviews, the latest news and much more - posted regularly, in a well-organized, highly navigable library.

We're also offering a Dundas Dashboard Bundle for SharePoint (with Chart and Gauge) for everyone who wants to take advantage of both products.

Updates

The What trust level is required for Dundas Chart for ASP.NET? article received some very minor updates this month.

We accidentally included references to some unreleased code in the Drill-down with Dundas Chart for Reporting Services article. While this might have been interesting (and we'll be telling you more about it soon), it also prevented people from using the reports included in the article. The downloads have been updated, but no changes were required in the article text.

Drilling Down in SharePoint

Drill-down

A useful feature of dashboards is the ability to click on a data point to see more detailed figures that make up its value. For example, on a pie chart with a slice for each country you might be able to click to be shown a chart with values for different regions within that country. This article describes the steps to accomplish this with SharePoint.

Grouping Data Together

Grouping data

A useful piece of functionality in Dundas Chart is to group data together and aggregate their values. For example, if you have more than one value for a given category and would like them grouped together, you can take the sum (total), average, minimum, maximum, first, last or count of all of the values in the category.

Tips and tricks for using Chart.

Sorting Data in Dundas Chart
There are some situations where your data points must be sorted in Dundas Chart, but the data source does not provide the data in order. For example, if you have unsorted data with a line chart you can see the line go back and forth across the chart, or if you are using the Chart.DataManipulator.Group() method the points must be sorted. Fortunately, Dundas Chart for .NET (all editions) and Dundas Chart for SharePoint provide sorting functionality built-in.
