Release Notes: The tag library was updated to the JSP 1.2 specification. Support was added for storing GraphContext in sessions, so that a graph Web app can be deployed in a cluster. This is done by setting the "org.faceless.graph2.UseSession" context-parameter to "true". Support was added for new Java 1.6 java.awt.LinearGradientPaint to XML. This is done by setting the Color attribute to match the format "gradient(c1,v1, c2,v2, [c3,v3, ...])", where "cn" is a Color and "vn" is the value where that color should be set.
Release Notes: The method signature of Key.addCustom(Marker) was changed to accept an AbstractMarker instead, allowing Text items to be used as Markers. No code changes are required, although code calling this method will need to be recompiled. The ability to create "funnel" and "pyramid" charts was added via the new setBarWidth(float, float) methods in GeneralBarSeries and the "topbarwidth" and "bottombarwidth" attributes in XML. The ability to place gaps between the bars in a Stacked Bar Series was added. The "autocolors" feature was added to Graphs to automatically choose colors in a certain range.
Release Notes: BFO have released an update to their Graph Library. This release fixes a number of minor rendering problems that could cause some minor visual facets, and is also faster. For output to SVG and PDF, or when plotting many thousands of polygons, this version can be up to 30% faster. It is less so when plotting to PNG (as most of the time is spent in the image compression).
Release Notes: The FunctionLineSeries has been modified slightly: there is a now a "complete" method for subclasses, and the "setLineSeries" method can retrieve the data from a LineSeries. A matching "series" attribute in the XML has been added. Labels on MultiBar graphs are correctly positioned. NaN values can be used in BoxWhisker series. The Graph Library can now be licensed using a license file.
Release Notes: The position of BarSeries markers when plotted against a DateAxis was fixed. A problem when plotting dates on one axis against times on another in non-UTC timezones was fixed. An exception when plotting striped backing paints against a top axis was fixed. A NaN error when plotting a LineGraph with only a single point was fixed.
Release Notes: Display order of markers on a non-3D graph is now deterministic. Markers, images, and labels on bar series appear in the correct place if the order of the bars is changed between series or if the series is part of a stack barseries. A label tag can be made into a hyperlink, and now accepts attributes such as href and onmouseover. It's possible to cause the GraphServlet to reject requests based on HTTP headers, via the "headercheck.N" init-parameters.
Release Notes: Support for Digital Signature timestamps was added. The ability to "remotely sign" a PDF via a Web service was added. The documentation was restyled for better layout in all browsers.
Release Notes: Some minor changes that allow graphs to be easily embedded in the Report Generator (under certain conditions) were made.
Release Notes: It is now possible to specify colors in XML graphs using the CSS3 syntax: rgb(), rgba(), hsl(), and hsla(). Graphs are now scaled correctly when one or all axes is a Gap or Log axis. setTimeZone was added to DateAxis and can be specified in the XML, eg. "date(dd-MMM-yyyy, UTC)", The rendering of area graphs when min value > 0 was corrected. The drawing of line series when there are no data points (only markers) was fixed. The Tag Library interface now plays nicely when interleaved with other tag libraries (eg JSTL).
