Context provides a charts module to create flow charts. The details are in the Charts uncovered manual by Pragma. There is also Flowchart creater to create flowchart code using javascript.
For example
\usemodule[chart] \setupFLOWcharts[height=3\lineheight] \startFLOWchart[example] \startFLOWcell \name {flow} \location {1,1} \text {Flow} \connection [rl] {chart} \stopFLOWcell \startFLOWcell \name {chart} \location{2,1} \text {Charts} \stopFLOWcell \stopFLOWchart \FLOWchart[example]
The more sophisticated example:
\usemodule[chart] \setupFLOWcharts [nx=5, ny=3, dx=2\bodyfontsize, dy=2\bodyfontsize, maxwidth=\textwidth ] \setupFLOWshapes [framecolor=black, background=color, backgroundcolor=white, ] \startFLOWchart[DSP] \startFLOWcell \name{input} \location{1,1} \shape{44} \connection[rl] {lowpass1} \comment[t]{$x(t)$} \comment[b]{$X(t)$} \stopFLOWcell \startFLOWcell \name {lowpass1} \location {2,1} \text {Low Pass\crlf Filter} \connection[bt] {adconv} \comment[r]{$x_f(t)$} \comment[l]{$X_f(t)$} \stopFLOWcell \startFLOWcell \name{adconv} \location{2,2} \text{Analog/Digital\crlf conversion} \connection[rl]{dsp} \comment[t]{$x[n]$} \comment[b]{$X(\Omega)$} \stopFLOWcell \startFLOWcell \name{dsp} \location{3,2} \text{Digital Signal\crlf Processing} \connection[rl]{daconv} \comment[t]{$y[n]$} \comment[b]{$Y(\Omega)$} \stopFLOWcell \startFLOWcell \name{daconv} \location{4,2} \text{Digital/Analog\crlf Conversion} \connection[bt]{lowpass2} \comment[r]{$y_d(t)$} \comment[l]{$Y_d(t)$} \stopFLOWcell \startFLOWcell \name {lowpass2} \location {4,3} \text {Low Pass\crlf Filter} \connection[rl]{output} \comment[t]{$y_f(t)$} \comment[b]{$Y_f(t)$} \stopFLOWcell \startFLOWcell \name {output} \location {5,3} \shape{44} \stopFLOWcell \stopFLOWchart \placefigure[here][fig:chart]{The path of signal in digital processing.} { \FLOWchart[DSP] }
Syntax for \connection
\connection [<from><to>] {<FLOWcell>}
<from>
and <to>
are the points from which point to which point the connection should be drawn. The following graphic depicts the names of the points.
-t t +t ---------------- +l | | +r | | l | | r | | -l | | -r | | ---------------- -b b +b
Example
The following code draws a line from the left top point of the current cell to the right bottom point of cell foobar
.
\connection [-t+b] {foobar}
