Displays an alert box with the given text.
Displays a dialog box to read in up to 6 values. If a var parameter is preceded by a name that starts with '$C'/'$W', a column/window menu is created. Use '$P..$' for a custom menu, '$X' for a check box. Example:
Input('$CColumn',c,'Time', t);
Sets the title of the dialog box that is invoked with the next call to 'Input'.

ax = xAxis or yAxis.
i=axis index.
Sets the error bar style for the next data set created using 'OpenDataSet'.
Cl,Ct,Lt = cap length, cap thickness, and line thickness in pts.
Use Cl=-1 for default length, Cl=-1 to draw error boxes.
