Editor's Note: Spring Cleaning

Now that spring is officially over in the Northern hemisphere, I'm going to be cleaning up the newsletter email database a bit. Invalid email addresses will be purged in an effort to help cut down on the waves of junk mail flowing around the Internet. I'm also taking some measures to make this newsletter appear even less like spam, so your automated email filtering systems will (hopefully) stop bouncing it as unsolicited commercial email.

Remember, if you get this newsletter in your email, it's because you signed up for it. If you've unsubscribed and you're still getting it, send me email and I'll personally remove your address from our mailing list.

If you've signed up and you stop getting the newsletter in your email, it's because messages to your address have bounced, and/or the newsletter has been rejected as spam. This article might be helpful.

Reporting poll

To help us plan our future developments, we'd like each of you to enter our reporting poll, to tell us about your current database reporting tool.

This data will be kept private (although next month we'll publish the results for you to see) and won't be used to pester you in any way (in fact, it's completely anonymous).



Tech·Ed 2008

Dundas was exhibiting at the Tech·Ed North America 2008 conference in Orlando, Florida earlier this month. Jeff Hainsworth, our Presales Consulting Lead, writes:

During the first week of June, Dundas had the utmost pleasure to attend Microsoft's Tech·Ed 2008. It was great to finally put a face to the names that have been in constant contact throughout the years and it was wonderful to see how many of you came by just to say "Hi!" We really appreciate the comments that you had about our products and our developers thank you very much for all of the great gifts of swag that many of you so graciously offered!

Everywhere you looked, Dundas was prevalent throughout Tech·Ed. A great majority of the vendors on the floor were touting products that used Dundas as the back end, including many of the Microsoft offerings. It was also not very difficult to see how excited Microsoft is that Dundas is going to be part of their new version of SQL Reporting Services. Pretty much every SSRS talk ended up being a Dundas Data Visualization demo. Thank you to everyone for making Tech·Ed a very successful show and we'll see you at the PDC in October!

How can I display formatted values in the OLAP Chart's labels?


The OLAP Chart shows the values for the members being displayed from the cube data provider. These values are raw numbers that lack any kind of formatting. Use a Customize event handler to provide formatting.

This month we're releasing four Add-ons on the Dundas Product Add-ons site, three for Chart and one for Gauge:

  • Extended Spline for Chart — Spline charts are great for smoothing out the data in a traditional line chart, but the "weight" of the curve can pull the line in unexpected ways. Use this add-on to find the actual minimum or maximum Y values of the spline itself, and to calculate the Y value for any X value between your series minimum and maximum, even if there's no data point there.
  • Point Selection Helper for Chart — Replaces the chart's zooming capabilities with a flexible data point selection event, letting the user select points by dragging with the mouse. The PointSelection add-on uses annotations (a Dundas Chart Enterprise feature) to mark the current selection rectangle.
  • Series Aligner for Chart — Changes any chart (which doesn't use dates for the X values) with missing data into a stacked chart. Normally, series with missing data cannot be included in a stacked chart.
  • Gauge Data Table Helper — The GaugeDataTableHelper add-on lets you add a small table containing your gauge's history data to the gauge container or to a specific gauge. The table is updated as the history data changes.
