Full-Size Display
Tap the stylus on a graph to pop-up a context-sensitive menu; select the Full-size option and the selected graph will be enlarged to fit the available screen area. This allows closer examination of graph detail.
The gridlines can be turned on or off via the Settings dialog, and provide a convenient visual alignment aid.
Use the context menu again to quickly return to the multi-graph display mode.
Zooming
MobiSpec supports zooming of graphs by tapping and dragging the stylus to mark an area with a "rubber-band"; when the stylus is lifted from the touch-screen, the display limits of the graph will be adjusted to match the newly-selected area.
It's also possible to select a vertical- or horizontal-only expansion region, by tapping and dragging the stylus in the desired dimension only; this can also be achieved by tapping in the axis-labelling area, outside of the actual graph display.
Peaks and Fractions
MobiSpec supports a high degree of color customization via the Settings dialog. The colors of all display elements are user-selectable: data outline, peak shading, peak baselines, fraction shading, background and axes can all be configured by the user.
In addition, the axis and label font sizes, and the number of decimal places in the peak labels, can also be specified by the user.
