Data Master 2000 provides a wide set of data visualization features.
View commands (by default, located in the View submenu of the main menu) should
be used to control visual data presentation.
Every data window has two viewers that display data
array associated with window: worksheet and plot. With View commands you may select
desirable data presentation - display only worksheet, only plot or both worksheet and plot
(note that you can set initial data window state in the Application Properties dialog box).
Plot viewer can display unlimited number of curves, or series. View commands
allow you to make 2D plots of your data. See also Serie Properties
dialog box (View|Properties|Current Serie) and Serie Manager
(Options|Serie Manager) window for more details about series management.
How to plot data in DM2000? Every plot has 8 preconfigured
series (to add more series, use pop-up menus of plot viewer and Serie Manager).
To be displayed, serie must reference a valid range of worksheet data, otherwise it is
invisible and treated as "empty". Initially all series are empty and you need to
define data range in order to display curves. Data range includes following values:
worksheet, first and last line, X and Y columns of the selected worksheet. If any of these
values are empty or first line is greater than last line, data range is invalid. Hence,
all you need to plot data is to correctly set data range of the selected plot serie.
Although you can define data range directly in the Serie Properties dialog box, View menu has a number of
special commands used to conveniently control data range of current serie (these
commands are not available if plot viewer is not active):
Plot Lines - copy selection of the worksheet referenced by current serie into the data
range. First and last lines copied from worksheet selection, X and Y columns copied from
values displayed in the worksheet header (see keyboard shortcuts
how to quickly select the range of worksheet lines and set X,Y column values). If only
single worksheet line (or cell) is selected, this command simply displays Serie Properties dialog box. Additionally, if data
window is in the "recording" state serie will be marked for automatic update
(see Monitor window for more information about window
control required for data acquisition).
Select Lines - this command performs "reverse" task: it selects worksheet
cells referenced by the data range of the current serie. Notice that in DM2000 worksheet
referenced by serie may belong to another data window
(by default, all preconfigured and newly created series reference worksheet
of the same window).
Select Serie - this command just make selected serie "current" (or active).
You may also use serie list from the main window toolbar or Serie Manager window to select series. The most of
operations in DM2000 applied to the data range defined by current serie.
Clear Serie - sometimes you may want to hide serie. At present serie objects in DM2000
cannot be deleted. Instead serie may be "cleared", or made empty by
setting XColumn=YColumn=FirstLine=LastLine=-1. Empty series marked by red "X"
icon and not displayed.
