12 Sept 2000: version 1.00 released


Upgrading:
Uninstall any previous versions of TPlot and the Misc package. Remove them from your hard drive. Then proceed with installation as outlined below. Note that the project group and package names change with every point release.


Installation:
TPlot requires the 'Misc' package for several utilities. If you define 'GIF' or 'PNG'
in 'Plot.inc', then it will also require TGifImage(http://www.melander.dk) and 
TPngImage (http://www.cdrom.com/pub/png/); also check out the 'GifPng_Rxx.dpk' project,
and add it to both of the Plot100_xxx projects (note: the PngLib package will provoke 
errors when Delphi exits).

	Delphi 1 & 2: 
		i. install the Misc components ('Misc/Misc_reg.pas')
		ii. install the TPlot components ('Plot/Plot_reg.pas')
	Delphi 3 .. 5:
		i. optional: open the appropriate project group 
                   (eg: 'Plot/Plot100_40.bpg')
		ii. open the Misc design-time package 
                    (eg: 'Misc100_40.bpl' = 'Misc/Misc100_40.dpk')
		iii. compile Misc and install it
		iv. open the TPlot design-time package 
                    (eg: 'Plot100_40.bpl' = 'Plot/Plot100_40.dpk')
		v. compile Plot and install it

        BC++3 .. 5: Delphi 3..5, but open the file with the BCB postfix
                   (eg: 'Plot/Plot100_30BCB.bpg')



Usage:
Click and drop all three components, TPlot, TPlotMenu and TPlotImageList onto a form.
Note that TPlotMenu does not work correctly under Delphi 1 (for unknown reasons),
and that TPlotImageList is only relevant to Delphi 4 / BC++4 or above.

Set the TPlot.Images, TPlotMenu.Images and TPlotMenu.Plot properties.

See the Help file for more detailed information on the use of TPlot.


Help File
There is a help file, but it always seems to be about 0.05 releases late.
Please be patient, and study the "Normal" demo project: TPlot is very easy to use.

Bugs
Please email bug occurrences to the author. Bugfixes are welcome.


Suggestions and Additions:
Are _YOUR_ property - but I'd encourage you to _SHARE_ them with myself and others.
