Toolbar

 

The toolbar consists of the following seven buttons:

Crosshairs
Select this button to view the coordinates of different points within the plot.  Up to 10 X-coordinates and 10 Y-coordinates, are displayed, one for each visible scale.  Upon selecting this button, the crosshairs are displayed in the plot area.  To determine the coordinates at a desired position, hold the left mouse button down, and move the crosshairs to the desired location.  To disable the crosshairs mode, deselect this button.

Zoom in/out
Select this button to zoom in on a specific window area within the plot.  Upon selecting this button, the mouse cursor changes to a magnifying glass when the mouse is positioned over the plot area.  Left-click on the mouse to indicate the start of the area to zoom in on.  Hold down on the left button to select the area.   Release the left button once the area to zoom in on has been selected.  The plot is redrawn to display the selected area.   Use the scrollbars or the pan function to view other segments of the graph.  To zoom out in stages, position the mouse over the plot area and right-click.  To view the complete graph again, select the Zoom out all button.  To disable the zoom in/out mode, deselect this button.

Zoom out all
This button is selected by default when the toolbar is first displayed.  Select this button to display all profiles in the plot in its complete form.   Scrolling is not required to view segments of the graphs.  Hence, the scroll bars are not visible and the pan function is disabled.

Pan
The Pan function becomes available when the chart is zoomed in.  Select this button to dynamically scroll the chart in any direction. Position the mouse at a specific location, then hold the left mouse button down to anchor the mouse to that chart location.  Drag the mouse to position the chart as desired.  When the left mouse button is released, panning stops.  To pan again, move the mouse to another chart location, hold the left mouse button down, and then drag the mouse to position the chart as desired.  To disable panning, deselect this button.

Save Image
Select this button to save an image of the chart to either a bitmap file (*.bmp) or enhanced metafile (*.emf).  The image is a capture of the chart as it is at that moment.  Upon selecting this button, a Save As dialog is displayed whereby you can enter the filename, specify where to save the file, and select the file type - i.e. bitmap or enhanced metafile.  Select the Save button to perform the save and close the Save As dialog.

Export Data
Select this button to save the chart data values to a tab delimited text (.txt) file.  Upon selecting this button, a Save As dialog is displayed where you can enter the filename, and specify where to save the file.  Select the Save button to perform the save and close the Save As dialog.  The entire contents of the chart data array is saved to file, along with a header line containing the profile names and scale labels.

Print Chart
Select this button to print the chart image.  The chart image is scaled to fit the printable area based on the paper size and the PrinterSettings properties - left, top, right and bottom margins and orientation (portrait or landscape).  The aspect ratio (height-to-width) is maintained.  The print dialog appears if PrintSettings.ShowDialog = True.

 

The display of the toolbar is user controlled through its Toolbar Visible property setting, or via its Toolbar Visible field in the General Property Page.
