Parametric Analysis 12

Now we can use the multiple X axes feature to view the original

waveform family for inductor L1 current along with the derived

rise time and overshoot data. We must first add a new plot by

selecting Add Plot from the Plot menu. To set this plot’s X axis

to a unique scale, select Unsync Plot from the Plot menu. You’ll

notice that the new plot’s X axis is now labeled with range and

variable information. However, it is still set for Performance

Analysis (with resistance R as the X axis label). We can toggle

off the Performance Analysis feature by selecting X Axis

Settings from the Plot menu and clearing the Performance

Analysis check box. This affects only the current plot. (The plot

marked with SEL>> is the current plot.)

Now we can add the trace for I(L1) as we’ve done before (Add

on the Trace menu), changing the Y axis range to 0A - 1.5A (Y

Axis Settings on the Plot menu), and the X axis range to 0s - 20s

(X Axis Settings on the Plot menu). This produces the display

shown in Figure 12-4.
