= BLT based plot window control commands =
The [[BLTWindow | BLT window]] offers control over the plot look and can allow you to save plots. The following [[BLTInterface | BLT interface commands]] are implemented as scripts, and use the tcl based pipes for passing information. TCL Return commands can be used to extract data which can be added to a plot surface. Multiple BLT windows can be opened at any one time.
; CreateGraphWindow
: Create a new plotting surface and return the file handle. The file handle is required as a parameter to the other [Post/BLTplot.html BLT window] commands.
; CreateLine
: Add a new line to an existing plot.
; CreateSingleLine
: Add a single data set to an existing plot.
; ClearGraph
: Clear a graph window of all data, and reset the window.
; AddtoLine
: Add one or more data points to an existing line in the plot window.
; CreateBound
: Add an outline to the graph. This can be then filled in with color in the plot window. Normal lines are not completed, and do not have fill properties.
; FlipY
: This allows the orientation of the y axis to be altered.
; SetLimits
: This allows the minimum and maximum value on a particular axis to be set.
; SetAxisType
: Set an axis to either log or linear scale.

Post Processing Commands

These commands allow data analysis and viewing in a simple way. It is not the point of these graphics to provide publication ready quality. It is often useful to dump data into a different program for annotation and preparation of final graphics. However, the graphics included do allow simple capabilities that are quite useful for analysis during the simulation.

Almost all of these commands work on a single data set. The data set can be named directly on those commands that require it. New data sets can be created with the select command using arbitrary expressions. The coordinate set contains 1-3 spatial coordinates and the selected variable as the final coordinate. In three-dimensional simulation, four dimensions are available and the data needs to be sliced to be displayed.

sel, select

This command allows a variable to be chosen as the z coordinate for the plot command to follow.

Select Examples

There are three main sets of commands.

TCL Returns

The first set is used to provide data back to tcl. These commands find/interpolate data and allow the information to be manipulated as tcl variables.

The interface command returns the location of the specified interface along a given line.

The interpolate command interpolates the selected plot variable and returns the position.

This command prints the material interfaces and integrated plot variable as a function of depth.

This prints the information along a specified line.

Plot commands

All of the following commands plot onto an blt window. The controls on the blt window are the same for all commands. This affords backward compatability to all of the old funcitonality (in most cases!).

This command allows the user to plot an isoconcentration line of the selected variable. It is usually used with the plot.2d statement.

This command allows the user to plot the selected variable in one dimensional cross sections through device.

This command allows the user to plot the outline and/or grid lines in the two dimensional mesh. It is very useful for setting up the display for the contours.
