This section is designed to highlight one or two features per issue that may be overlooked because they are not made visually obvious with an icon or a menu item.
Multiple Y Scales
Micro-Cap has the capability of having multiple Y scales for a single analysis plot group. With multiple Y scales, it is easy to compare diverse waveforms on the same plot. For example, a current and a voltage waveform may each be analyzed in the same plot with appropriate scales for each waveform. This lets both waveforms be visually compared without having to zoom or scale the plot. To enable multiple Y scales, simply go to the desired analysis, click on the Scope menu and disable (no check mark) the Same Y Scales option. Upon running the analysis, a separate Y scale will be produced for each unique entry in the Y Range text field. If two or more waveforms share the same Y Range value, then only one scale will be created for those waveforms. The color of the shared scale would be the color of the first waveform in the Y Expression text field column that shares the scale.
The figure below displays the transient analysis results when the file PRLC.CIR is simulated over 1us. In this analysis, a voltage waveform, V(1), with a scale of 8V to -2V and a current waveform, I(L1), with a scale of 400mA to -100mA are both plotted in the same graph.
The default state for Micro-Cap is for single scales. To change the default state for all future circuits, click on the Options menu and go to Preferences. In the Preferences dialog box, click on Analysis/Performance Defaults and disable the Same Y Scales option. All new circuits would then have multiple scales as their default.
