csDrawGraph - ASP Chart Component

This is an ASP component for creating graphs and charts on the fly. The resulting graph can be streamed to a browser or saved to a file. It can be used with default settings to create graphs quickly and easily, or customised to suit your web page.

Produce 2D bar charts and pie charts dynamically from an ASP script.
Plot simple line graphs containing multiple lines.
Stacked bar charts can show multiple values in each bar.
Export graphs in GIF format or PNG, with optional transparency.
Full control of colour, size and font styles including support for Unicode.
Optional linear trend lines can be added to bar charts.
Produce an HTML image map for the chart.
Built in default settings allow graphs to be produced with a few lines of code.
Available as 32 bit or 64 bit.

Using ASP to generate graphs makes it easy to integrate the display with the rest of your web application. Generating a GIF or PNG image allows a clear image to be produced, with optional transparency. Control over colours and text styles enables you to make your charts fit in with an existing web site design.

There are a wide range of properties that control the appearance of a graph. Most of these properties can be left at their default values allowing a graph to be produced relatively quickly. The overall size can be varied, including the length and position of the axes. The total values can be shown on bar charts and pie charts. A prefix or suffix can be added to these values to display currency or other units. Text annotations can be added, and on line graphs the plotted coordinates can be used. For full details see the online manual.

csDrawGraph is a COM object and can be used with other COM enabled applications. It is not restricted to classic ASP. We have an OCX control, csXGraph, which is more suitable for use with visual programming tools. csDrawGraph can run in ASP.NET once it has been registered using late binding or more efficiently using early binding.

csDrawGraph supports Base64 encoding, allowing the component output to be placed directly into an HTML image tag as a string, so the ASP code and image can be in the same script.

This component must be registered on the server before it can be used. It is available as a 32 bit or 64 bit component.

Here are some simple examples showing graph types:

We have some demos that you can view or download:
