When None is assigned as a line style, the line is no longer displayed but the symbols assigned to the curve remain visible, creating a scatter plot of the curve. The curve is still displayed in the legend.

Any of the 64 colors can be assigned to a curve. Select a color from the color palette to change the color of the selected curves.

Symbol Attributes

Symbols can be placed on a curve to indicate data points.

There are nine different symbols available. To mark the data points on the currently selected curves, select a symbol from the symbol palette.

The frequency of the symbol placement is determined by the Every field. By default, Every is set to 1 so symbols are placed at every data point. To change the symbol frequency, enter a number in the Every field. For example, if Every is set to 5, a symbol is placed at every fifth data point on the curve.

Any of the 64 colors can be assigned to a symbol. Select a color from the Symbol Attributes color palette to change the color of the symbols on the selected curves.

Scatter plots can be created by setting the line style of a curve to None and then assigning a symbol to the curve.
