Next, a Y value is calculated for each grid point. The range of this grid is equal to the range of the data. A two-dimensional grid of X and Z is constructed. The 3D surface plot is based on a set of three-dimensional points. The color of a cell is proportional to its position along a color gradient. The heat map is a two-way display of a data matrix in which the individual cells are displayed as colored rectangles. The Clustered Heat Maps (Double Dendrograms) procedure can be used to plot hierarchical clustering in two directions. The procedure in NCSS that produces these plots also has a variety of circular data analysis calculations and tests to analyze, for example, mean direction or circular distribution comparison. Each of these plots displays the distribution of the data around the circle. The circular histogram and the rose plot are common graphics used in the analysis of circular or angular data.

Error-bar charts in NCSS software can be vertical or horizontal, grouped or ungrouped, and can be displayed with boxes or with individual points. NCSS also has a procedure for three-dimensional scatter plots, shown in a later section.Įrror-bar charts are used to display means and associated spread, through the standard error or standard deviation. Some of these features are trend lines (least squares) and confidence limits, polynomials, splines, loess curves, border box plots, and sunflower plots. NCSS includes a host of features to enhance the basic scatter plot. The scatter plot is one of the most powerful tools for analyzing continuous response data. Hazard function and hazard rate plots are also available in this procedure. The Kaplan-Meier Curves (Logrank Tests) procedure can be used to plot the Kaplan-Meier product-limit survivorship function as well as the point-wise confidence intervals (example shown below).
