How to speed up the plotting?

If fast plotting is required, first make sure you are using Fast Line as line type. This can be set at the bottom of Plot->Advanced Plot Settings..., in the Curve type list box.

Note that these settings apply for the active plot type only.

The plotting speed can be additionally improved using two methods. The first method has no side effects and has a great effect on the speed; it is simply to set the curve width to size 1. If it is not set to width 1, the plotting is much slower. Set the width in Plot->Default Curve Styles..., this will apply to all plot types. Make sure that all the curves in the dialog box have width 1. Also at the bottom of the dialog box, make sure that Display active curve with width is set to 1.

The other method gives very efficient plotting for large amounts of data, e.g. for large *.wav-files. From Plot->Advanced Plot Settings… check . If this setting is on, the points in between the points plotted are simply skipped independent of what part of the curve is displayed. This will affect all the plot-types originally having more elements than the maximum limit. Please note that the skipped points will not appear when zooming in, therefore it is not recommended to use this option on a fast PC. The plotting range can also be limited by checking .

Finally the plotting after each measurement can be turned off from Measurement->Measurement Tasks..., by making sure is not checked.
