Ged Mead (XTab) is a Microsoft Visual Basic MVP who has been working on computer software and design for more than 25 years. His journey has taken him through many different facets of IT. These include training as a Systems Analyst, working in a mainframe software development environment, creating financial management systems and a short time spent on military laptop systems in the days when it took two strong men to carry a 'mobile' system.
Based in an idyllic lochside location in the West of Scotland, he is currently involved in an ever-widening range of VB.NET, WPF and Silverlight development projects. Now working in a consultancy environment, his passion however still remains helping students and professional developers to take advantage of the ever increasing range of sophisticated tools available to them.
Ged is a regular contributor to forums on vbCity and authors articles for DevCity. He is a moderator on VBCity and the MSDN Tech Forums and spends a lot of time answering technical questions there and in several other VB forum sites. Senior Editor for DevCity.NET, vbCity Developer Community Leader and Admin, and DevCity.NET Newsletter Editor. He has written and continues to tutor a number of free online courses for VB.NET developers.

This project creates a more versatile and better looking bar chart. It splits the main drawing tasks into separate procedures. However, the code is still rather unwieldy and this makes a strong case for creating a 3DBar class with settable properties for width, depth, height, color, etc. It would then be possible to include properties well beyond the UI choices we have used here, and of course it conforms more closely to the OOP approach to developing in VB.NET.
In this article I explained or used the following:
- Bitmap object
- Do While Loop
- Font object
- Graphics Object
In the next article in this series, we will move on to another, sometimes more dynamic, type of chart - the line chart.
