DeltaPoint has taken the five-star DeltaGraph Pro 3.5... and made it better all around while avoiding the pitfall of introducing new problems. Version 4.0 retains its predecessor’s biggest advantages — simple interface and excellent libraries of stock graph types — and remains an ideal compromise between scientific and business graphing...
In version 3.5, data sets larger than 20,000 points could produce odd behavior or crashes; the new version can handle a 30,000-point set with no problems other than a predictably long wait to import the data. But despite being bigger and more option-laden than 3.5, 4.0 is faster at most tasks — for example, on a Power Mac, charts pop onto the screen as soon as you select a type. Little formatting touches have been added; you can now rotate text arbitrarily, scale chart views over a giant range, and drag axes to highlight data details.
Two important additions fill in some convenience gaps. Previously, you could paste an equation onto a chart as a graphic element, but you had to create the equation using other software. Design Science’s Equation Editor is now incorporated into DeltaGraph, so scientific users can show on charts the data-description formula they found using DeltaGraph's remarkably effective curve-fitting facility. The other key addition is improved integration with Microsoft Excel 5.0, including dynamic chart linking and importing blocks of cells (rather than just entire worksheets).
Additions to the chart gallery are the only other important upgrade elements. Build-up charts (for displaying parts of a total), survival charts for biomedical practice, broken-axis charts, x-y column charts, variable-width barcharts, and floating-bar and column charts fill out the gallery; only a few seldom-seen statistical chart types and some odd financial charts that stock-market analysts use are missing.
DeltaGraph still allows you to organize slide shows and view them in outline or thumbnail mode (although you'll probably use the program to feed graphs into Microsoft PowerPoint, which would then generate the bulk of the presentation). As another plus, the handling of tick marks has been refined, and 2-D area charts can now have grids superimposed. Frankly, it’s hard to see what’s left for version 5.0, except perhaps to make the whole show a collection of OpenDoc parts.
The Last Word DeltaGraph is reasonably priced, it works conveniently with Excel, it's easy to use, and it has even graph type you are likely to need. It's the answer to almost even graphing question, and a key parr of your Mac number-crunching software repertoire.
