Plot Page - Contour Grid Maps

To view and edit contour data map plot properties, select the map and then click the Plot tab in the Property Manager. You can then change the data file, axes, and worksheet columns and rows; show or hide fill contours and color scales; configure blanking lines and fills; and set or reset levels in the contour grid map.

 

Set the contour data properties in the Property Manageron thePlottab.

 

Plot Type

The Plot type property displays the type of plot.

 

Grid

Click the existing grid file path and file name next to Grid to select a different grid file for the plot. Click on a currently open grid file or click the Browse option to navigate to a grid file that is not yet open. Select a different grid file in theOpen Worksheetdialog, and click theOpenbutton to change the data. The plot automatically updates.

 

Smoothing

The Smoothing option applies a smoothing algorithm to the contour lines. To change the Smoothingoption, click on the existing option and select a new one from the list. Available options are Low, Medium and High. The more smoothing that is applied, the more likely that contour lines could cross or be located incorrectly based on the gridded values.

 

Y Positioning

On XZ contour grid maps, the Y positioning adjusts the position of the XZ contour map on the Y axis. This number is expressed as a percentage of the total Y axis length, e.g., an entry of “50%” will position the XZ contour map about halfway up the Y axis. To change the Y positioning, highlight the existing value and type a new value or click the to increase or decrease the value. Press ENTER on the keyboard to make the change.

 

Overlay

On XZ contour grid maps, select a surface map from the list next to Overlay on which to overlay the XZ contour map. Note: the surface map must be part of the same graph as the XZ contour map. To change the Overlay, click on the existing option and select the new option from the list. All surface maps in the existing graph will be listed.

 

To overlay a contour map and surface map:

  1. Create a contour map using the Home | New Graph | Contour Surface | XZ Contour Data Map or Home | New Graph | Contour Surface | XZ Contour Grid Map or Home | New Graph | Contour Surface | XZ Contour Function Map commands.

  2. Add a surface map to the graph using the Home | Add to Graph | Plot command.

  3. Select a Surface Function Map, Surface Data Map, or Surface Grid Map and click OK.

  4. Select the axes and click OK.

  5. Select the data file or grid file and click Open.

  6. Click on the contour map in the Object Manager or plot window to select it.

  7. In the Property Manager, click on the Plot tab. Change the Overlay to the surface map.

  8. Click on the surface map in the Object Manager or plot window to select it.

  9. In the Property Manager, click on thePlot tab. Set any desired overlay properties.

 

Change Axes

Click on the axis name next to the X axis, Y axis, or Z axis fields to change the axes used for the plot. Select another axis name from the list. Alternatively, click Select plots/axis to change the axis used by several plots on a graph at once.

 

See the Axis - Add to Graph page for information about how to add a new axis to the graph. Once the new axis is added to the graph, it will be available in the X axis, Y axis, or Z axis lists.

 

NoData Line and Fill

The line properties for NoData regions are specified on the Line page in the NoData Line Properties section. The fill properties for NoData regions are specified on the Fill page in the NoData Fill Properties section.
