I want a software or someway to display a chart (anykind) to contain 4
kinds of information. Say, for example, I want a chart to show a data
set that contains the width,height,lenth and price of some products. I
have tried Excel's bubble chart, but that can only display three kinds
of data.
Any software is OK, but it must contain at least a demo version that I
can verify the results.
Or, if you can possible program one, I will pay more to do this.

I need Windows Solution...I don't have a mac..and don't wanaa buy one

There is a program called 'Gigawiz' that will allow you to plot a 4-D
contour point charts as well as a 4-D scatter charts using color
coding for the 4th variable.

See examples here:

http://www.gigawiz.com/ChartsG14.html

There is a demo available but the program only runs on certain models of the Mac.

In addition, to purchase it is somewhat expensive - US$349 for a single license.

In that case, check out Grapher 6.0: 

http://www.goldensoftware.com/products/grapher/grapher.shtml

It will allow you to create a 3D bubble plot that shows the change in
four variables.

A demo is also available.


Alternatively, have a look at XLSTAT-3DPlot:

http://www.ozgrid.com/Services/excel-3d-charts.htm

This is a plug-in for Excel that allows you to plot various types of
charts in three dimensions.

Sorry, XLSTAT-3DPlot is not a standalone program (it requires an
installation of XLSTAT-Pro) so is probably not a practical solution.

Another option is to use the bubble chart, but use concentric circles
for two dimensions (in addition to the two dimensions used for the X/Y
plot).

The automatic data ranges don't work so well for this, but if you go
into 'Source data / Series' it's easy enough to set up two series with
the same X and Y values, but different size values.

Format the second series to have no fill, so it won't hide the first
series even if that size value is smaller.

Note that the same scaling will be used for the two size dimensions -
in other words, if one is in the range 1-10, say, and the other is
10,000-100,000, the first will be almost invisible.  So, if this is a
problem, scale the units of one or the other before you plot them, so
they're in the same range.

Hope this helps!
