Polar Plots
Polar plots display data on polar coordinates, using degree, radian, or grad data versus a radial distance. The degree, radian or grad data are displayed on a circular angle axis. The second axis is a radial axis showing the distance from the center of the circle. Polar plots can display mathematical functions, line/scatter data, bars, or classed scatter plots. As with all graph types in Grapher, you have complete control over all aspects of the graph.
Polar line/scatter plots display data as a line, as symbols, or as a combination of line and symbols. Alter line colors, symbols colors, or add labels.
Polar line/scatter plots can use the same symbol or varied symbols for point locations.
Add lines connecting the points or display only the symbols.
Polar class scatter plots allow symbols to be based on a range of data values in a worksheet column. In addition to class scatter plots, regular symbol plots can be created with different symbols based on information in a column or in a symbol table.
Display classes with different colors or shapes. Limit your points to inside the polar area
or allow points to go outside the area. Use text labels for axes for clarity.
Polar bar charts are bars that are displayed using radius and angle values in a worksheet. The bar is shown at the length (radius) indicated in the worksheet cell. Alter line colors, fill colors, or bar width. Bar charts can be stacked or adjacent, when multiple data exists for each value.
Stacked polar bar charts allow comparison of multiple sets of data on polar axes.
Polar function plots are lines, symbols, or both that display a mathematical function in polar coordinates.
Create multiple plots on the same graph and add colors to differentiate between each curve.
Radar graphs, also known as spider plots, are new in Grapher 8! The radar plot has a similar appearance to other radial graphs, except there are multiple radial axes and no angle axis. A radar graph is a graphical method of displaying multiple variables. Comparisons between multiple radar plots typically show trends in your data.
Radar plots have an additional axis for each new variable. Display multiple data sets on the same graph,
overlaying the plots, and filling with a partial transparency to see all the options.
Rose diagrams display statistical data like a histogram, showing the number of occurrences of an event that fall within a specific angular region. Bins are fully customizable in rose diagrams!
Show unidirectional or bidirectional data on a rose diagram.
Wind Charts graph frequency vs. wind direction. Bins are created according to the wind speed. The frequency can be viewed as counts, relative frequency, or as percentages of relative frequency. Bins are fully customizable!
Display polar wind charts using class colors.
The stacked classes reveal the total distribution in each wind direction.
