The graphic manipulation toolbar provide tools to create, configure bars, curves, layers, pies chart, etc. The user can modify the stacking order of the graphics frames.

Screen shot: Graphic manipulation toolbar

First section of the toolbar:

• The first button exits frame creation mode. The second button on this toolbar shifts XQuad into frame creation mode. This button allows the user to return to default frame or cell selection mode
   
• The second button creates a rectangular frame.
  1. Click on the display screen to place one point of the rectangle.
  2. Move the mouse to stretch out the rectangular form.
  3. Click again to place the opposite diagonal point of the rectangle to create the frame.

  This operation is affected by magnetism. It can be cancelled during step two by clicking the right mouse button. To create a square, press shift while stretching the rectangle.

   

Second Section of the toolbar:

All frames are positioned on different planes. With these tools the user may modify the stacking order of frames.

• The first button shifts the selected frames to the foreground, above all others.
   
• The second button shifts the selected frames to the background, beneath all others.
   
• The third button brings the selected frames forward by one plane, exchanging its place with the frame just above it.
   
• The last button pushes the selected frames backwards by one plane, exchanging its place with the frame just below it.

Third Section of the Toolbar:

• The first button creates or changes a histogram graph. A histogram represents values using vertical bars. The X-axis of the graph is divided equally between the various series, and each series section is subdivided equally for each value. The histogram legend displays a color for each value of the series.
   
• The second button creates or changes a bar graph. A bar graph represents values using horizontal bars. The Y-axis of the graph is divided equally between the various series, and each series section is subdivided equally for each value. The bar graph legend displays a color for each value of the series.
   
• The third button creates or changes a line graph. A line graph represents values using a two dimensional line for each series. The X-axis is divided equally between the various series values. The line graph legend displays a color for each value of the series.
   
• The fourth button creates or changes an area graph. An area graph represents values using a two dimensional surface area for each series. The X-axis is equally divided between the various series values. The area graph legend displays a color for each value of the series. These values are added to corresponding values of preceeding series before being reported in the graph.
   
• The fifth button creates or changes a pie graph. Pie graphs represent values using angular sections of a circle for each series. Each disc is divided into positive values above zero (zero and negative values are not included). Each section is identified by its color and the amount of space it occupies on the disc. A pie graph legend displays a color for each value of the series. A pie graph has no Y-axis.
   
• The last button creates or changes a radar graph. A radar graph represents values using two dimensional polar lines resembling a radar antenna. For each X-value a line extends forth from a central point, equally spaced from other lines. Each series value is reported on corresponding axes, creating a colored line between the axes. The radar graph legend displays a color for each series.

The buttons in this section fulfill two roles: creation of framed graphs based upon data from selected cells, or alteration of a selected graph. The function of these buttons therefore depends on what is selected: worksheet cells or a frame containing a graph. When one of these buttons creates a new graph, XQuad shifts to frame creation mode; once defined this frame will contain the new graph. If XQuad cannot determine the exact area of a selected cell region, the "Graph Configuration" dialog box is automatically opened.

Fourth Section of the Icon Bar:

The buttons in this section modify the configuration of the selected graph.

• The first button displays/hides the Y-axis. This button can be applied to all graph types except pie graphs. Y-axis lines will be extended across the entire width of the graph.
   
• The second button displays/hides the legend. Depending upon graph type the legend can be displayed or hidden if series or X-axis titles exist.
   
• The third button displays/hides X-axis titles. X-axis titles exist when the third button of the graph configuration dialog box is engaged.
   
• The fourth button displays/ hides series titles. Series titles exist when the fifth button of the graph configuration dialog box is engaged.
   
• The fifth button displays/hides the graph title. A graph title exists only if series titles and X-axis titles exist.
   
• The last button changes the area of cell regions which are the source of values reported in the graph. This button opens the graph configuration dialog box.

Last Section of the Toolbar:

• This button locks selected frames. Locking a frame prohibits all movement and modification of the frame. A locked frame within a selection can render the entire selection inalterable. The mouse cursor takes on the shape of a "Do Not Enter" sign when pointed at a selected locked frame. This button is engaged when one of the frames in a selection is locked. To unlock a frame selection, deactivate this button.
