ASP.NET Charting with NPlot

Three years ago I wrote an article here on 4Guys titled ASP.NET Charting Using Office Web Components (OWC) that examined how to use OWC as a charting engine in ASP.NET applications. OWC is still a very powerful charting engine, but unfortunately it carries with it some serious drawbacks:
* OWC is a COM library, which needs to be installed on the ASP.NET web server. If you do not run your own web server, you may have difficulty getting these libraries installed.
* Calling COM librar...

With this product you can convert a True Color image to palettized one using Floyd-Steinberg dithering algorithm. GDI+, by default, uses a halftone palette, that creates ugly looking, poor quality images. New algorithm gives images without grain looking just like original ones. This is especially useful for photography. In order to use the new conversion technique, you just need to copy one file. This is useful for hosting servers because you don't need to register any components....

Read Reviews | Write Review |  Your Rating: 

Most Microsoft® ASP.NET controls are designed to be browser independent; they generate plain HTML markup that the majority of browsers easily understand and process. As a page developer, you can control to some extent the version of the HTML language used to generate the browser response. Some of the ASP.NET controls (for example, validation server controls) detect the capabilities of the underlying browser and adapt their response accordingly. In many cases, this means that the markup is enrich...

A powerful and common use for data-driven web pages is to create an on-line report. While text-only reports are nice and all, any report can be easily snazzed up by adding an impressive looking chart. One way to add charts is to use an ActiveX control, like MSChart. The advantage to using such an approach is that MSChart is very powerful. With it you can easily have a multitude of charts drawn: 3d graphs, line graphs, pie charts, etc. The major drawback is that the user must first download the A...

Using the System.Drawing class allows you to create images on the fly. But how do you get them into a web page? Since the tag requires a path to the image file, you cannot stream the dynamic image into it (in other words, it is not like a picture box on a winform). The following article will show a method for getting the dynamically generated image into your web page....

The purpose of the series will be to build a class that allows any C# programmer access to common, and not so common, image processing functionality. The reason we are doing it in C# is simply that I want to learn it, but the functionality we use is available through GDI+ in C++, and indeed the code to do the same thing using a DIBSECTION is not terribly different. This first article will focus on per pixel filters, in other words, filters that apply the same algorithm to each pixel 'in place' w...

When companies move to the Web, they often pour hundreds of hours and thousands of dollars into one task: creating images that display text labels. Labels whose image content consists only of text improve the look of companies' browser-based interfaces.
