The Impulse/Frequency Properties dialog lets you specify:

The Style of plot. You may chose from the following:

• Auto. One of the following styles will be chosen automatically based on the plot type and the number of data points.
• Line. The plot consists of a series of straight lines, which connect consecutive data points.
• Dot. The plot consists of dots at each data point.
• Line and Dot. This combines the Line style with the Dot style by plotting each data point with a dot, and connecting consecutive dots with a straight line.
• Vertical Line. The plot consists of thin vertical lines that end at each data point
• Stem. The plot combines the Vertical Line and Dot styles.
• Bar. The plot consists of thick vertical, outlined lines.
• Stair. Similar to Bar but only the top of the bars and part of the sides appears, resulting in a stair-like appearance.

If the Origin at Zero box is checked, or if the plot is an impluse plot, the lines/bars for the Vertical Line, Stem, and Bar styles will originate from zero, that is, the X-Axis.  Otherwise, lines/bars will originate from the minimum Y value.

You can also specify the plot Style using the Impulse/Frequency menu or the popup (context) menu which appears when you right-click the mouse over a plot.

Other Options. The following other options may be selected:

• Auto Titles. The Main, X-Axis, and Y-Axis titles are generated automatically.
• Magnitude in dB. Magnitude is shown in decibels, rather than linear units.
• Integer Point Reduction. When there are more data points than pixels, data reduction is necessary to show the data on the screen. For example, if the screen (or window) has 800 pixels across, and the data consists of 8000 points, then exactly 10 data points are represented in each pixel. But what if there are 10000 data points? Then there must be "12.5" points per pixel. So in the second example, when Integer Point Reduction is selected, each pixel would represent only 12 data points, and therefore only the first 9600 points would be plotted. On the other hand, if this option is unchecked, the number of data points varies with each pixel in order to achieve the required average. So in this example, the number of data points represented in each consecutive pixel would alternate between 12 and 13.
• Sum Frequency Magnitude in Plot Lines. This option affects only Frequency Magnitude plots. When checked, the magnitudes of each data point represented in the pixel are summed, and the pixel sum is plotted; otherwise the data point with the largest magnitude for each pixel is plotted.
• Zoom Full Decade in Log Plot. If checked, any zoom region of a log plot will be automatically increased so as to show full decades.
