A net chart is similar to polar or radar graphs. They are useful for comparing data that are not time series, but show different circumstances, such as variables in a scientific experiment or direction. The poles of the net chart are the y-axes of other charts. Generally, between three and eight axes are best, any more and this type of chart becomes confusing. Before and after can be plotted on the same chart, or perhaps expected and real results, so that differences can be compared.
Two net diagrams showing totally fabricated data from totally fictional experiments.
- Plain net chart without grids and with just points no lines.
- Net chart with lines and points and grid. axes colors changed as well as labels. chart area color = gradient quadrant and the points changed to fancy 3D ones.
There are also varieties of net chart that show the data series as stacked numbers or stacked percentages.
