Note: @DRD should be used in combination with @DRM, @DRT, @DRI. Refer to @DRI for detailed explanation.

Note: SHIFT key acceleration can be initiated by holding SHIFT+Arrow key. The effect can be seen more clearly for large data plot. By holding SHIFT+Arrow keys, data reader Increment starts at 5 points and then gradually accelerates controlled by @DRI [% of previous step] in every @DRT [msec] until @DRM [% of data plot size] is reached. These numbers are relative to data plot size normalized with @DRD=10000 points by default. The normalization means slower acceleration rate for smaller data plots (<@DRD points) and higher acceleration rate for larger data plots (>@DRD points). This dependency is logarithmic.

Note: @DRM should be used in combination with @DRD, @DRT, @DRI. Refer to @DRI for detailed explanation.

Note:@DRP=-1 (default), data reader will display data point’s original decimal places. @DRP=0 data reader will display no decimal places. @DRP=1, data reader will display one decimal place.

It is useful for instrument data that is prior to 2018.

Note: @DTD=640 makes the actual bitmap resolution proportional to screen resolution (640*1280, 800*1600), so that 2-3 pixel symbols are selectable.

Note: @DTF can be regarded as the resolution of freehand drawing tool. The smaller @DTF is, the smoother the freehand drawing would be. If set @DTF=100, freehand drawing looks similar to plot with data points connected by lines.

Note: when click to select a graphic object, there are some green square handles around the object which can be used to adjust the position and shape of the graphic object. These green squares are the draw tool handles mentioned above.

Note: refer to @DTO for the meaning of click free area.

Note: @DTN=0, select an object and press arrow key, it still moves and accelerates when you hold the arrow key still. When @DTN is negative, it will move in opposite direction to arrow key direction. @DTN can also be used as step size for Zoom-Panning Tool and rotation for 3D object.

Note: click free area refers to area within which single or double click will have no effects, such as to select, bring up dialog box. Point of click defines the region within which Origin object can be clicked to select.

Note: @DTR=10, the ellipse drawing is not smooth anymore. @DTR actually defines the resolution of ellipse object.

Note: @DTS=5, the curved arrow drawing is not smooth anymore. @DTS actually defines the resolution of curved arrow drawing.

Note: beyond the region mentioned above while still inside legend box, a single hit will select the border and along with text inside meanwhile displays green handles around the box.

Note: For example, RGB(0,64,255) = RGB(00,40,FF), you can use LabTalk command hex3Dec to convert it to decimal number as following: hex2Dec(FF4000)=16728064. The default color is Blue in transient state.

The default value is an internal color code of RGB(255,255,255). You can use the color function to get this internal color code for the desired color.

Persistent

Note: the expression to calculate bin size is as: bin = (max - min) / (1 + factor * log10(npts)). If @HBS and @HBN are not specified, @HBF will be used to make automatic bin size estimate.

Note: @HBM is for number of bins that is not rounded so that it is the exact number of bins (could be non-integers). @HBM=0 means this global variable is not used. The priority of @HBM is behind @HBN.

Note: @HBN=0 means this global variable is not used. The priority of @HBN is behind @HBS.

Note: @HBS=-1 means this global variable is not being used and default auto bin size will be used.
