Scatter Plot Options

Displays a dialog box that allows you to specify the appearance of 3D scatter plots. To edit any of the X,Y,Z components on a plot of random points, use the Edit Data command on the Edit menu.

View

Azimuth - view angle around the z axis. 0 degrees is looking in the positive X direction; 90 degrees is looking in the positive Y direction.

Elevation - view angle from the horizontal. 0 degrees gives an elevation view; 90 degrees is looking straight down at the surface. For a pseudo-2D top-down view with X axis at the bottom of the plot and the Y axis labels along the left side of the plot, use elevation and azimuth both equal to 90 degrees.

Angles control - the graphic below the Elevation text box allows you to select viewing angles with your mouse. Click within the circle to change the viewing angles. The center of the circle represents an elevation angle of 90 degrees (looking straight down at the surface), the inner circle is 45 degrees, and the outer circle is 0 degrees (viewing along the XY plane). The 3D unit axes will rotate as you move the mouse across this control. View angles will not be changed until you click within the circle.
You cannot select a negative elevation angle (looking up at the surface from underneath) using this control. To use a negative elevation angle enter the value in the Elevation text box or click on the corresponding spin button.

Scale Factors

Specifies how the X, Y, and/or Z values are stretched or compressed. This has no effect on the actual input values, only the proportions of the plot. Use a negative scale to invert the normal drawing direction, e.g. use a negative Z scale to draw the plot with positive Z in the down direction.

Color Based On

Z Value - Colors used to draw symbols are based on the Z value of the point. For this option, the number of levels and the high and low values are set in the Z parameters box.

Data Set - Each data set is drawn in the same color. You can have up to 100 data sets in a scatter plot.

View Depth - Colors are based on the distance of a symbol from the viewpoint.

Colors

Choose between a smooth gradation of colors ranging from magenta to red, black to very light gray, or a custom blend of 6 colors that you specify.
