Oberon Function Plotter is an advanced VBA macro add-on for CorelDRAW 10, 11, 12, X3, X4 and Corel DESIGNER 10, 12 that allows you to plot parametric function graphs by defining the functions in analytical form. There are quite a few programs that allow to create function lots already however most of them are self-contained modules with limited editing and illustration capabilities. Oberon Function Plotter coupled with the editing power of CorelDRAW provides the highest output quality.
If you are a student preparing your math paper or a scientist doing a scientific report, Oberon Function Plotter will help make your work precise and appealing. Even if you are a designer and look for certain curve patterns for your design, Oberon Function Plotter is for you.

Function Plotter for CorelDRAW 10:
This program requires CorelDRAW 10 Service Pack 1 (10.427) or later. Correct functioning under the original release of CorelDRAW 10 (10.410) is not guaranteed. This program will not run under earlier versions of CorelDRAW.
If you don't have the latest version of CorelDRAW 10, download the service pack(s) from Corel web site: http://www.corel.com/support/ftpsite/pub/coreldraw/draw10suite/index.htm
You have to have Visual Basic for Applications installed to run this program. VBA is not installed by default with CorelDRAW 10 Graphics suite. You need to do a custom installation and choose to install VBA. You can run the VBA install manually by running the vba6.msi installation package from \Corel\Graphics10\Config\Redist\VBA6 folder of the CorelDRAW 10 CD#1.
Function Plotter for CorelDRAW 11/12/X3 and Corel DESIGNER 10/12:
A retail version of CorelDRAW/Corel DESIGNER is required.
You must ensure that Visual Basic for Applications is installed along with CorelDRAW / Corel DESIGNER.
Run the setup program and it should install all the files for you automatically. Make sure that you have VBA installed beforehand. The setup program also creates a new workspace that is automatically made active. You can revert to your previous workspace by just going to Tools>Options>Workspace in CorelDRAW and selecting the workspace that you want.
To launch Oberon Function Plotter, start CorelDRAW first. If during installation you specified that you wanted to activate Function Plotter workspace in CorelDRAW, you will see a new button on toolbar:
You can start Function Plotter by clicking this button. The same command also appears on the Tools menu.
If you didn't activate the workspace during installation, you still can start Function Plotter by going to Tools>Visual Basic>Play... menu to bring up the VBA Macros dialog:
Select "Plotter (Plotter11.gms)" item from Macros in list and start the macro "Main.StartPlotter" by selecting it in Macro name list and clicking Run button.
Oberon Function Plotter is a shareware product. It is fully functional in the downloaded version however it has an evaluation period of 14 days. You need to register the program to continue using it. The registration fee is US$25.00.
The same registration number can be used to install Function Plotter for CorelDRAW 10, 11 and 12.
