Creating Bar Chart Maps

RockWorks | Utilities | Maps | Barcharts

This program reads location data and values for up to 9 selected variables from the RockWorks datasheet, and generates a map with mini-bargraphs at each sample location. The resulting map is displayed in RockPlot2D.

Step-by-Step Summary

Menu Options

• Spatial Filter: Insert a check in this box at the top of the program window to activate a data filter based on spatial coordinates. Click this button to enter the filter settings. Click the Return to Previous Menu button when you are done entering the filter settings. (More info)
• 
  
• Time Filter: Insert a check in this box at the top of the program window to filter the borehole Aquifer or T-Data based on date/time. This only applies to the Borehole Locations layer, if activated. Click this button to enter the filter settings. Click the Return to Previous Menu button when you are done entering the filter settings. (More info)

• XY Columns: Use these prompts to tell RockWorks which columns in the input datasheet contain the input coordinates.
  Click on an existing name to select a different name from the drop-down list. See a sample data layout below.
  • Easting (X): Column that contains the X coordinates for the sample locations.
    These can be Eastings in meters or feet, decimal longitudes, etc. See Defining your Datasheet Coordinates for more information.
  • Northing (Y): Column that contains the Y coordinates for the points.
  • The columns containing the values to be represented in the bargraphs are defined below.
  • 
    
• Components: Click this tab to select the items to be represented in the barcharts.
  • Plot Component # 1 - Plot Component # 9: You can request up to 9 components be represented in the small bar charts by inserting a check in the appropriate check-box. For each component that you activate, choose the data source and color.
    • Data Column: Click on the drop-down prompt to select the name of the column containing the data listing for that component.
    • Color: Choose the color for that component's bar.
    • 
      
• Diagram Options
  • Individual Diagram Dimensions: Select a width and height for each mini-bar chart, expressed as a percent of the map width. Examples:

  • 

  • Labels: Insert a check here if each bar in the bar charts is to be labeled with its component's name.
    • Size:
      • Choose Automatic for RockWorks to determine the optimal size for the text.
      • Choose Manual to define a specific label size, as a percent of the map width.
        • Size: Click to the right to enter the label size as a percent of the map width.
    • Label Angle: Click to the right to enter the angle. In the examples above, the text is plotted at "180", or reading to the south. (Recommended.) Enter "0" for vertical labels reading to the north.
    • Include Values: Check this item to include the component value in addition to the name.
    • Decimals: Enter the number of decimal places to be represented in the value labels.
  • Borders: Check this box to include thin-line borders around each bargraph.
    • Background Color: Click to the right to choose a background fill color for the graphs. In the examples above, the color was set to white.
    • 
      
• Automatic Offset: Check this box to have the program automatically offset the bargraphs such that they do not overlap adjacent bargraphs. Click on this tab to set up the offset parameters. (More info)
• 
  
• Map Layers: Select the additional layers you wish to incorporate into the map, inserting a check-mark in those you wish to include. Establish the settings for each activated layer, such as a background image, axis labels, etc. See 2D Map Layers for more information.
• 
  
• Output Options
  • Save Output File: Check this to assign a name for the map in advance, rather than displaying it as Untitled.
    • Automatic: Choose this option to have RockWorks assign the name automatically. It will use the name of the current program plus a numeric suffix, plus the ".Rw2D" file name extension.
    • Manual: Choose this option to type in a name of your own for this file.
  • Display Output: Check this option to have the resulting map displayed in RockPlot2D once it is created.

Step-by-Step Summary

1. Access the RockWorks Datasheet program tab.
2. Create a new datasheet and enter or import your data into the datasheet.
   Or, open one of the sample files and replace that data with your own. See Data Layout for datasheet examples.

   ! Click the Example buttonat the top of the window to load a sample file that is installed with the program.

   This example illustrates the sample file "RockWorks Data\Samples\Soil_Properties_01.rwDat".

   

   Longitude and latitude coordinates must be in decimal format. If you're using another coordinate system, be sure you've specified the Units and the Projection Settings as appropriate.

3. Select the Utilities | Maps | Barcharts menu option.
4. Enter the requested menu items, discussed above.
5. Click the Continue button to proceed.

   The program will read the selected components from the indicated columns of the datasheet. It will normalize the values and generate small bargraphs at each map location using the requested color and size. The completed map will be displayed in a RockPlot2D tab in the options window, if requested.

6. You can adjust any of the settings in the Options window (scalar, colors, etc.) and then click the Continue button again to regenerate the map.
7. View / save / manipulate / export / print the map in the RockPlot2D window.
