mode
SetAllPlots
Selects or deselects all stat plots.
SetTblGraphDraw
Sets the graph to dirty, which causes a complete regraph the
next time the graph is brought to the display.
Stat Plots
Stat plots provide a way to display data stored in list variables. The SetAllPlots routine
will select or deselect all stat plots. Each stat plot has a portion of System RAM
allocated to store its settings. To select/deselect or change settings for an individual
stat plot, you must modify this RAM.
There are three bytes that determine if a plot is on or off:
P1FrqOnOff
Plot 1, 0 = off; 1 = on
P2FrqOnOff
Plot 2, 0 = off; 1 = on
P3FrqOnOff
Plot 3, 0 = off; 1 = on
The high 4 bits of these bytes determine which axis the data will be plotted on if the plot
type is Normal Probability Plot. 0 = X axis, 1 = Y axis.
There are three bytes that determine the type of plot to be drawn:
P1Type
Plot 1 type
P2Type
Plot 2 type
P3Type
Plot 3 type
0 = Scatter Plot
1 = XY Line
2 = Modified Box Plot
3 = Histogram
4 = Box Plot
5 = Normal Probability Plot
