The flow chart shown in the window can be scrolled using the vertical and the horizontal scrollbars of the flow chart window respectively. In addition to the scrollbars you can use the arrow keys and the mouse wheel for scrolling the flow chart. With the mouse wheel you can scroll both horizontally and vertically. Scrolling with the mouse wheel alone scrolls the view vertically, and using the mouse wheel with the Shift key pressed down scrolls the view horizontally. The scrolling area is limited to half of the model's size outside the model. The modeling area grows every time the model size grows, for example after creating new objects. This way you will not run out of drawing space. If the process level does not contain any objects, scroll bars are disabled. By default the flow chart is positioned in the middle of the drawing area in order to allow flexible expanding of the chart into any direction.
For zooming you can use either:
Zoom factor drop down list
Zoom factor slider. Quickly access any zoom size between 10% and 200%. Double-click the slider to scale the flow chart to fit into the window.
Decrease zoom factor. Each click of this button decreases zoom by 10% and moves the slider accordingly.
Increase zoom factor. Each click of this button increases zoom by 10% and moves the slider accordingly.
Fit to screen. Clicking this button will show the whole flow chart in the window.
Mouse wheel: Hold the Ctrl key down and scroll up to zoom in or scroll down to zoom out.
If you want to view the flow chart in a smaller size, select Point and zoom out tool and click on the flow chart at a center for zooming out. Alternatively drag the zoom factor slider to the left from the current position.
If you want to adjust zooming to a certain percentage use the Zoom factor drop down list. You can either select one of the predefined factors from the drop down list or type in your own percentage. The zoom factor must be between 10 and 1 000 %. Use Whole Chart to quickly show the whole flow chart in the window.
With the zoom factor slider you can quickly access any zoom size between 10% and 200%. Just press the mouse button down over the slider and drag it to the desired position. The flow chart is updated in real time while the mouse button is pressed, so you can easily find the optimal size without additional attempts.
