Why use a Charting Control instead of a shrink-wrap application?

A number of reasons:

1. Customization: When working with Charting Controls, you design the user interface and the data storage, so all the dialog boxes meet your precise needs, and use the terminology your people are used to. Although products like QA-Shop Floor offer a great deal of this type of customization, there may be additional features you'd like, or you may want to simplify the interface to do only what you need.
2. Cost:  When deployed across an organization, the cost of the control licenses and the development effort could be less than a shrink-wrap deployment. This, of course, is highly dependant on the cost of the shrink-wrap products, and the features that you choose to implement, since shrink wrap SPC applications, such as Quality America's SPC-PC IV or QA-Shop Floor, require no programming what-so-ever. 

What are the advantages of Quality America's charting control compared to competitors' or to developing my own control?

Advantages include:

1. History of Leadership: Why buy an SPC Control from a vendor who is not recognized for their expertise in SPC and proven history of SPC software development? Quality America has an established position of leadership in each of these key areas. 
2. More Features! Not only do we provide more charts than any competition, we also offer more of the analysis features, like Non-normal analysis, Stepped control regions, right mouse functionality, and subgroup attachments. 
3. QA-ActiveSPC also includes a Gage Control, which allows you retrieve data from electronic gages and Data Collectors.
4. Great looking graphics!
5. Easily integrates with any popular container, including Microsoft Visual Basic, Microsoft Access, Borland Delphi, Microsoft Visual C++

How easy is the charting control to use?

Simple. With just a few lines of code QA-ActiveSPC can analyze your data and generate a chart. Here's an example using Microsoft's Visual Basic:

' Set ChartType to 1 for X-Bar and Range chart

QAChart.ChartType = 1

' Add the Data

QAChart.AddRegion

QAChart.Regions(1).AddSubgroup

QAChart.Regions(1).Subgroups(1).AddItem 5.82

QAChart.Regions(1).Subgroups(1).AddItem 5.51

QAChart.Regions(1).Subgroups(1).AddItem 5.92

QAChart.Regions(1).AddSubgroup

QAChart.Regions(1).Subgroups(2).AddItem 5.29

QAChart.Regions(1).Subgroups(2).AddItem 5.71

QAChart.Regions(1).Subgroups(2).AddItem 5.54

QAChart.Regions(1).AddSubgroup

QAChart.Regions(1).Subgroups(3).AddItem 5.37

QAChart.Regions(1).Subgroups(3).AddItem 5.31

QAChart.Regions(1).Subgroups(3).AddItem 5.45

' Do the analysis and generate the chart - That's it!
