Assignment: to plot a bar graph (vertical and horizontal)

In MATLAB a bar graph displays the values in a vector or matrix as
horizontal or vertical. The default is to scale the x-axis to the
highest x-tick on the plot.

Calculators, more elaborate ones, such as Matlab, feature
calculations, graph functions, and inequalities and data sets.

In other words, they are calculators for basic matrix operations.

A scientific calculator for Windows plots functions and diagrams with
many chart/graph combinations through programmable functions, but how
might these structures be treated as entities to be carried across the
Internet as variables?

(see below for an example of how this might look)

Chart::Graph - search.cpan.org

EXAMPLE: xrt2d

#make sure to include Chart::Graph
use Chart::Graph::Xrt2d qw(xrt2d); xrt2d(\%options, \@data_set);

#say for example we have a 3 by 4 matrix

1 2 3
1 search.cpan.org/
2 ~caidaperl/
3 Chart-Graph-3.2/
4 Graph.pm

This gets complicated with programs like Matlab, because not all
matrices can be inverted, or used as the denominator in matrix
division: {however don't count it out yet}

To make a graph of y = sin(t) on the interval t = 0 to t = 10 we
plot(t,y) and use the vector of t and y values to construct the
graph.

Chart::Graph::Gnuplot
1 search.
2 cpan.
3 org

Data can be presented to Chart::Graph::Gnuplot in one of 3 formats for
the convenience of the user: \@matrix: an array reference of [x,y]
pairs of data ...

1 search.2 cpan.3 org/
1 perldoc
2 Chart
3 Graph
4 Gnuplot

Here is what a potential added function to the above configuration
might look like:

R Graph Gallery (159)
Image scatter plot matrix
ipairs function produce image
scatter plot matrix large datasets
colors encode density points in scatter plots

1 addictedtor. 2 free. 3 fr/
1 graphiques/
2 RGraphGallery.
3 php
4 graph=159

Here is how we might force the recreation of the graph and matrix:

matplotlib: python plotting + Matplotlib v0.99.1.1 document

1 draw
2 Force redraw - current figure.
3 errorbar
4 make an errorbar graph
5 loglog
6 a log log plot.
7 matshow
8 display matrix new figure
9 preserve aspect
10 pcolormesh
11 make pseudocolor plot
12 use quadrilateral mesh

(cont'd. example two)

1 matplotlib. 2sourceforge. 3net/
1 R Graph Gallery (158)

BEGIN

1 Image lag plot matrix
2 Produce image lag plot matrix large timeseries
3 color encode density points in lag plots.

CLOSE

Functional Interface:

Chart::Graph::Xmgrace

1 search. 2 cpan.3 org

Jump to MULTIPLE DATA SETS IN MATRIX FORM‎:

(example)

showshow=show command show
showshow=shows how (command)

To graph more complicated datasets:

use Chart-Graph interface:

1 search. 2 cpan. 3 org/
1perldoc
2 Chart::
3 Graph::
4 Xmgrace

OLAP Graphs!"

These commands are loose only to provide a workable path in the right
hands.
