...sample data points/display only some symbols
SigmaPlot supports data point sampling, which is very useful under a number of different circumstances. Data sampling is controlled from the Data panel in the Graph Properties dialog box. You can change or reset the
sampling from these options at any time. Sampling is particularly useful for:
You can also create overlaid sampling plots using this feature. e.g., you can choose not to draw symbols at every point in the plot.
- Create a line plot of all you data.
- Add another plot of the same, this time a scatter plot.
- Open Graph Properties, and for the scatter plot, reduce the data point sampling to the desired level. It helps to change the colors of the plot to
more effectively distinguish the symbols from the lines. Also, use the Apply button to see the effect of the change without closing the dialog box.
