Editor's Note: Spring?

If it's spring already, why is it still so cold?

We've been busier than usual here at Dundas, rearranging things and expanding to fill a larger space. Nothing like the quiet sounds of construction and the pastoral scent of paint and new carpeting to drive your productivity!

The Chart challenge!

Add-ons

Stacked Bar Gauge

Dundas Product Add-ons are fully commented source code libraries that provide you with additional features and functionality. These are free and can be used in any project that utilizes a Dundas component (such as Chart, Gauge or Map).

Over the past month, we've updated most of the add-ons to work with SharePoint and Reporting Services. When we release new add-ons, they'll include support for these environments as well as the usual ASP.NET and Windows Forms versions.

Featured Property

This month's feature Chart property is ChartArea and its Axis (AxisX and AxisX2) object's RoundAxisValues() method.

When called from a paint event, the RoundAxisValues() method tells the chart to automatically create maximum and minimum values for the axes (using the axis' Interval property). It will leave an Interval gap between the data points and the chart area border.

The RoundAxisValues() method affects only the X axes, as the Y axes are already calculated in this manner. Calling RoundAxisValues() on a Y axis has no effect.

Featured Property

The designer for the Reporting Services version of Dundas Gauge lets you set actions for the entire gauge object. What if you want to configure an action for a specific item, such as a pointer?

Using the "Creating a Drill-Down Chart through code" techniques described in this support article, we can employ the MapAreaType, Href and Parameters properties found on gauge components (such as a circular or linear gauge's Pointers property).

For example, in the PostApplyData event (in the Gauge Designer's Code Editor), use code like this to allow drill-down from a pointer to the CircularGauges.rdl report.

gaugeContainer.CircularGauges[0].Pointers[0].MapAreaType = MapAreaType.Report;
gaugeContainer.CircularGauges[0].Pointers[0].Href = "CircularGauges.rdl";
gaugeContainer.CircularGauges[0].Pointers[0].Parameters.Add("Name", "Value");

The idea is to set the MapAreaType property to indicate that this is a URL, use the Href property to specify the link or drill-down target, and the Add() method of the Parameters property to add any variables (as name/value pairs) required for the target.

Note that you can use Gauge keyword values while setting Parameters to pass to the drill-down chart.
