2.1.12 Graph variables and special tables
Special variables for graphs and tables serve to indicate to PowerStudio that a graph or non-
standard table is desired. On a non-standard graph or table the values that appear in the X and Y axis,
rows and columns on a table, may switch from one type to another, depending on the variables
represented. For a better understanding of these graphs and tables see the section on the java client.
When you want to make special graphs or tables, such as the waveform or harmonics, it will
be necessary to use the following variables.
Maximum voltage harmonics (3 sec.)
Maximum voltage harmonics (10 mins.)
effective semi-circle voltage
