Pseudo-section Grid Section Parameters

The Grid Section Parameters dialog lets you define parameters related to the display of a "section" grid.

Grid Section Parameters dialog options

Labels

Title

The text for the section label, plotted to the left and/or right of the section. If none is specified the file name, without path or extension, is used.

Script Parameter: IP.GLABEL# (# is an integer from 1 to 8)

Units

Secondary text, printed below the section label at two-thirds the height. Can be used for printing the units.

Script Parameter: IP.GUNITS#

Clipping

Bottom clip elevation

Some grids may go to a greater depth than desired, and take up too much room in the plot. This allows parts of the grid below a certain elevation to be clipped. If left blank, no clipping occurs. The grid is always clipped at the top to the local topography.

Script Parameter: IP.ZCLIP#

Contours

Major contour(s)

Minor contour(s)

Check the boxes in order to enable contouring of the section values.

If no more than a single value is specified for both the major and minor contours, then the values are used as an interval; i.e. a single value of "50" in the Major contour(s) and a single value of "10" in the Minor contour(s) will result in major contours at 0, 50, 100 etc., and minor contours at 10, 20, 30, 40, 60 etc. If one field is left blank, while the other has one value, then only the filled in value is used as an interval – this lets you choose to plot just minor or just major contours by intervals. If multiple values, separated by commas, are specified in either the Major or Minor contour(s), then the values are interpreted as specific single values, and contours will be drawn only for those values. If the Major contour is set to 0, contouring is disabled. The default setting is to disable contouring, and the interval is set to 0. Values are automatically ordered for the contouring algorithm.

Script Parameters: IP.CINT#, IP.CINTMIN#

Logarithmic

If selected, the grid will be contoured using logarithmic contours at levels 1, 1.5, 2, 3, 5, 7.5 when the dynamic range (max/min) of the data is below 100,000; and 1, 2, 5 when above.

Defined

If a single value is specified for both the major and minor contours, then the values are used as an interval; i.e. a single value of "50" in the Major contour(s) and a single value of "10" in the Minor contour(s) will result in major contours at 0, 50, 100 etc., and minor contours at 10, 20, 30, 40, 60 etc. If only the major contours are plotted, and only one value is specified, then that value is used as an interval.

If multiple values, separated by commas, are specified in either the Major or Minor contour(s), then the values are interpreted as specific single values, and contours will be drawn only for those values. 

Colour Zone File

Select the colour scheme for rendering the image of the grid. If you mouse over the colour scheme entry, a tooltip will display the name of the colour table in its folder. To modify the selection, click on the colour entry and then navigate through the scheme categories.

Script Parameter: IPPLOT.COLORFILE#

Browse

Select a colour zone file. The zone file maps colours onto defined ranges of values in the grid.

Define

Define a colour zone file. Various transform options are available.

Application Notes

The script parameters are created by taking the given values and replacing the "#" with the numbers 1 to 8., e.g. IP.CINT#.
