Working with histograms

You can create, format, print, and/or remove histograms in BoundarySeer.

Creating a histogram

  1. Choose "Histogram" from the "Data" menu found at the top of the BoundarySeer window, or found by right-clicking on a data set in the project window.

  2. Choose the data set and the variables you wish to view from the pull-down boxes in the dialog. Hit "OK" to view the histogram.

Formatting and editing axis labels

You can format and edit axis labels by double-clicking on the axis. Double-clicking will call up a window where you can rename the axis and specify a new font for the label.

Formatting a histogram

You can format the bars and axes of a histogram by right clicking in the histogram window and choosing "Properties." This brings up the properties dialog that allows you to change the attributes of the axes and the bars on separate tabs.

Axes

To change the scaling on the axes, set the minimum and maximum value shown for the X and the Y axes. You may also specify the number of tick marks for each axis of the histogram, or you may wish to let BoundarySeer choose the tick marks automatically by checking the box. To change the thickness of the axes, choose a line thickness from the pull-down box next to "Line:".

Bars

You may also change the color of the bars. Up to three colors of bars may be displayed on one histogram and these can be changed separately (change primary color, secondary color, or tertiary color). Most histograms will have only one color, though histograms of Boundary Likelihood Values for fuzzy wombled boundaries can have all three. You can also change the number of bins into which BoundarySeer divides the data.

Printing

You can print a histogram when the histogram is the active window. Click on the window to activate it. Then, go to the toolbar and choose the print button print.gif, or from the menus, File > Print.

Removing a histogram

If you want to remove a histogram from a project, click on the "close" icon close.jpg in the upper right corner. This permanently removes the histogram. If you remove a histogram accidentally, you may re-create it (assuming you haven't also removed other important files such as data or boundary layers).
