KnowWare International has added a 3D Histogram to its QI Macros™ SPC Software for Excel. The 3D Histogram is part of the Histogram Comparison Template, and also includes a regular histogram and a Weibull histogram. QI Macros works with Excel to draw Lean Six Sigma charts and graphs.
A histogram is commonly used to show process capability after process stability is established. Histograms show the spread or dispersion of variable data. Histograms show the spread, or dispersion, of variable data. The customer's upper specification (USL) and lower specification limits (LSL) determine how well the process delivers on customer requirements. Measurements outside of the spec limits represent data points that don't meet customer requirements.
The QI Macros SPC Software contains 40+ charts and more than 90+ fill-in-the-blank templates that simplify Lean Six Sigma complexities. QI Macros SPC Software for Excel works with Excel versions 2000-2013. At only $229 (thousands less than competitors), they are the least expensive, most robust solution available on the market.
