[FIX] major bug, positioning of graph items was not working at all. Action: removed X1 and Y1 (redundant, described as alias of X and Y). Their 0 value were overriding the original X and Y values.

[UPD] Renamed AxisFill to GraphFill, AxisBorder to GraphBorder, AxisRect to GraphRect so axis and graph space becomes two correctly separated things.

[NEW] MasterPaneFill and MasterPaneBorder properties

[NEW] Transparency is shown as squares in the designer.

[REM] PNG transparency is supported in FireFox. To get it also in IE6 or less, you must use the IE7 javascript http://dean.edwards.name/IE7/ like this:

<script>

window.IE7_PNG_SUFFIX = "\\.png(?:\\?.*?)";

[NEW] Added and updated some comments

19-Nov-2005 (by softlion)

Major changes to the web interface:

DataSource property works. Optional DataSource are also available on each curve, by default it uses the main DataSource. DataMember property is available as a main property for the base axis (x axis) and as a property on each curve (y axis).

New RenderMode property to render as an IMG tag instead of generating and returning an image on the fly. A temporary image file is created and saved in the folder specified by the new RenderedImagePath property. The file name is the control ID (may change in a near future).

Comments uptdated and added on properties

Property categories change for readability (ASP.NET pages made with previous version will need to upgrade)

Major and minor grid properties for all axis are now grouped into a child item

minor bug fix: image generated on the fly also sends HTML IMG tag
