The format of Graph, Double Graph, SPT Graph, Water Content Graph, Bar Graph, Geophysical Log, Double Geophysical Log, and Lithologic Cross-Plot columns can be changed, by selecting the column and using the Customize button on the Columns tab. When this button is pressed the Customize Graph Columns form will be displayed.
If the column type is a double graph or double geophysical log, then the Customize Graph Columns form will have two tabs as shown on the next page. Each tab is used for one of the graphs or geophysical logs. The data entry for both tabs is identical.
The Customize Graph Columns form can be used to set the following parameters:
Graph Title: This is the title to use for the graph (up to 255 characters). The Graph Title will be displayed in the same area as the Column Title. It is recommended that either the Graph Title or Column Title be used, and not both. If the column type is a double graph or double geophysical log, then both Graph Titles will be displayed over top of each other.
Units Title: This is the units of the graph (up to 255 characters). The unit title will be displayed below the graph title.
Minimum: This is the minimum value for the horizontal axis of the graph. If the value is zero, the program will calculate the minimum value based on the data specified.
Maximum: This is the maximum value for the horizontal axis of the graph. If the value is zero, the program will calculate the maximum value based on the data specified.
Increment: This is the increment to use for labelling the horizontal axis of the graph. If the value is zero, the program will calculate the increment based on the data specified.
Log Scale: The horizontal axis can have either a linear or a logarithmic scale.
Show Grid: To draw horizontal and vertical grid lines, set Show Grid to yes.
Horizontal Spacing: This is the horizontal spacing of the grid lines, usually the same as the scale increment. If set to zero, the scale increment will be used. If Show Grid is set to no, this field will not appear.
Vertical Spacing: This is the vertical spacing of the grid lines, usually the same as the scale increment. If set to zero, the scale increment will be used. If Show Grid is set to no, this field will not appear.
Grid Line Style: This is the line style to use to draw the grid. When the Line Style button is pressed, the Line Properties form will be displayed. This form can be used to set the line style, width, and color.
Fill Area Under Curve: The curve formed by the graph points can be filled with a solid color. The fill will be between the left side of the column and the curve.
Fill Color: This is the color to use for the fill. When the Color button is pressed, the Color form will be displayed. This form can be used to select a basic or custom color. If Fill Area Under Curve is set to “no”, this field will not appear.
Connecting Line Style: The data points for the graph can be connected by a line. To change the line style, press the Line Style button. The Line Properties form above will be displayed. This form can be used to select the line style, width, and color. If the line style is set to “none”, no line will connect the points.
Point Type: The graph data can be shown as circles, crosses, squares, squares, triangles, or inverted triangles. To not show the data points, select “none”. If this is a Bargraph column, the point type is set to “none” and this field will not appear.
Point Size: This is the size of the data points. If the Point Type is set to ‘none’, this field will not appear.
Point Color: This is the color of the data points. To change the color, press the Color button. The Color form will be displayed. This form can be used to select a basic color or a custom color. If the Point Type is set to “none”, this field will not appear.
Label Points: The values of the data points can be drawn above each point. If the data value is less than the minimum value, the value will be shown with a “<” symbol. If the data value is greater than the maximum value, the value will be shown with a “>” symbol. If the Point Type is set to “none”, this field will not appear.
