Use this dialog box to specify isoline values, fill colors and line styles.

Displays the smallest and largest z-value from the original data. This information is useful when it comes to choosing isoline values.
Isoline Values
The list box displays isoline values, line style and fill colors. The values are listed in ascending order. The first line always displays the isoline value min. The min isoline value is necessary to define a color fill for the smallest data area.

There are two methods to insert values to this field:

  1. Enter a single number or
  2. Enter a range of values in the form Minimum, Delta, Maximum and then click the Insert button.

Example: The input of 100,10,130 generates the isoline values 100, 110, 120 and 130.

New values will be automatically inserted in the correct position. Only isoline values that are not already in the list will be transfered to it from the edit field.

A maximum of 99 different values can be entered.

One of the selected isoline values in the list will be copied into the edit field. Edit the value and then click the Change button. The new value will be added to the list box and the old one will be deleted from the list.
To delete isoline values from the list, select the unwanted values with the mouse and then click the Delete button.
Line Style
To specify the line style for one or more isolines, select the isoline values in the list box and then click the Line Style button.
Fill Color
To specify the fill colors for one or more isolines, select the isoline values in the list box and then click the Fill Color button.
Isoline values can be generated with this function. The values displayed in the list will be deleted and the number of new values that were set in the Number box will be inserted into the list. The values will be chosen to enable the isolines to be distributed as regularly as possible onto the entire plot.

To select an autoscale type check the box Autoscale.

Standard: This type creates a number of isolines which are evenly distributed in the x/y plane.

Steps 1,2,5: This type creates isoline values in steps of 1, 2 or 5 or multiples of this value (10,20,50 or 100, 200, 500 etc).
