273) Where can I get a bar graph widget?

[Last modified: Nov 96]

Answer:  (Loox added Nov 96) The LOOX dynamic graphics and data visualization
package includes 2D and 3D charting widgets. The 2D Grapher widget can display
up to 30 simultaneous charts of 15 different types, including bar, histogram,
pie, candle-stick, high-open-low-close and others. The widget supports user
interactions, automatic update and scrolling.

The 3D grapher widget displays 3 or 4 dimensional data as a surface, 3d bar
chart, isoline or ribbon charts. Features include interactive scale and
rotation of the 3D surface, plus a large number of configurable resources.

Answer:  You can fake one by using for each bar a scroll bar or even a label
which changes in size, put inside a container of some kind.

Try the StripChart widget in the Athena widget set. Set the XtNupdate resource
to 0 to keep it from automatically updating.

KL Group sells two graphing widgets which both do bar charts. Greg Kiessling
of KL Group writes:

XRT/graph displays 2-D data in virtually any type of bar chart, X-Y plot, pie
chart, area graph, financial graph or logarithmic scientific chart.  It has
over 200 resources to fine-tune the graph's appearance and behavior.  Other
features include fast-updates, text areas, 3D-look on bars and pies, time-
axis, user-interaction hooks and a graph builder tool.

XRT/3d displays 3-D data in surface plots, contour graphs and bar charts. It
has over 140 resources, and will automatically contour and zone 3-D data using
custom or default distribution tables. Users can automatically rotate, zoom
and scale views. Other features include 4-D graphs, projections, histograms,
text areas and user-interaction hooks.

Both XRT/graph and XRT/3d can be programmed using resources, UIL and C++.
They are easily integrated into popular GUI Builder tools. They both support
PostScript output. There are no run-time, distribution or royalty fees for
distributing end-user applications. For more information email info@klg.com or
