Q:
What do you need to run Joho?
A:
Joho
runs on desktop Windows 95, 98, ME, NT, and XP computers. We recommend at least 64 Mbytes of RAM, a 15-inch monitor, a
mouse, and a CD-ROM drive for software installation. Joho requires 256-color operation. |UP

Q:
Can Joho run on a server?
A:
The Joho display system is designed for the desktop.
Its performance in a server environment depends on the details of
that environment. Joho’s
Matrix Computation System, which performs computational tasks and image
creation can be run on a server, which can then transfer output files to
folders accessible from the desktop for display.

Q:
Can Joho
get data from network drives?
A:
Joho
on the desktop can use input files and create output files on any
network accessible drive and folder. |UP

Q:
How much storage does a Joho image require?
A:
Joho
images are very small compared to the original data files.
This makes Joho an effective mechanism for archiving numerical information. The
actual formula is
Size_in_Bytes = 2048 +
(N X (Columns X Rows X Levels))
N = 1 for a
displayable Joho image. N = 4 for a floating point image used for calculations.

Q: How
much information can I show in a Joho image?
A:
This depends on the resolution you set in your display settings.
In practice about half of the screen will be used for the legend,
titles, labels, and blank space. Joho
images can use one pixel on your screen for every number.
If you use 800x600 resolution you can see about 240,000 numbers. If you use 1024x768 you can see about 400,000 numbers.
If you use 1280x1024 you can see about 650,000 numbers. Double
these numbers if you forego the labels. |UP

includes a comprehensive User’s Guide that describes all of Joho’s
operations. It also
includes example data files, and detailed instructions processing the
example files. |UP

Q:
What training is available?
A:
On-site training is available and priced according to the customer’s
needs. Unlimited telephone
support and assistance is included in the maintenance price.

Q:
What does Joho cost?
A:
A single-user desktop license for the complete Joho
system is $2,999. Maintenance
(bug-fixes and unlimited telephone support) is $400/year.
Multiple, site, and enterprise licenses are available.
Major upgrades will be priced according to the additional
capabilities in the newer system. |UP

Joho’s
Capabilities
Q:
Can you distribute Joho images on the web?
A:
In order to use Joho’s
interactive features (reading out values, dynamic color changes) you
must be using an installed copy of Joho.
However, Joho creates
highly compressed PNG versions of the screen images (and thumbnails).
You can store these PNG images in a folder that is accessed by
web pages. Most browsers display PNG images.
Joho
can create batch scripts to create PNG versions many images without user
intervention. |UP
TO TOP|
Q:
Does Joho print images?
A:
Yes. Double clicking a Joho image opens the standard Windows printer dialog.
In addition, Joho can create batch scripts to display and print many images
without user intervention. |UP
TO TOP|
Q:
Can users view Joho images without installing Joho?
A:
Users can view the static PNG versions of Joho
images with any browser and many viewer programs.
The user needs Joho in
order to interact with the images.
|UP TO TOP|
Q:
Can Joho create images automatically?
A:
Joho
remembers all of your image creation and manipulation operations in
script files that it can use for repetitive, independent operations.
For example, Joho could automatically read a daily updated data file, create an
updated image, convert it to a PNG version, and place it in a web
accessible folder to update a web site with new images without user
intervention.
Joho
scripts can be combined with simple batch files to automate complex
tasks. |UP
TO TOP|
Q:
Can Joho archive data?
A:
Joho
can keep all of its working files for a project in a single folder.
Saving this folder to secondary storage is very practical.
Because Joho images,
and the scripts to display them are very small, saving numerical data in
Joho format can provide a significant reduction in the necessary
storage capacity. |UP
TO TOP|
Q: Can Joho
combine images mathematically?
A:
Yes. Joho
includes a variety of mathematical functions to manipulate Joho images after it creates them from original data files.
For example Joho makes it trivial to compute changes or percentage changes from
one image to the next, without having to manipulate data in the original
file or database. |UP
TO TOP|
Q: Can Joho
images be used in PowerPoint and other
programs?
A:
Joho’s
PNG format images can be inserted into most Windows image compatible
programs. |UP
TO TOP|
Q:
Does Joho perform statistical analysis?
A:
Statistical analysis is often performed because there is no practical
way to view large data sets. Joho
breaks this barrier by showing all of the original data, its trends, and
its anomalies. In cases
where statistical analysis is still required, Joho
is an excellent tool for verifying the data quality and for showing what
analysis is appropriate for the data.

Using
Joho
Q:
How do you get data into Joho?
A:
Joho
includes a Microsoft Excel spreadsheet reader that converts spreadsheets
directly into Joho images
that include column and row labels and titles. It also includes an Excel
macro that creates images from spreadsheets where assumptions in 2 or 3
cells can vary.
Joho
also includes a very flexible text file reader program that can read
most ASCII data files that can be generated from standard database
queries. |UP

Q:
What if we need special software to read our data into Joho?
A:
Joho’s
Matrix Computation System is extensible by American Image programmers.
If you have existing data files that are not readable with
existing Joho programs, we
can quote the price of added functionality for your site’s version of Joho.
|UP TO TOP|
Q:
Can Joho remember where my data is located?
A:
Joho’s
project profiles include paths to five different folders and extensions
for fifteen different file types. The user can set these and store them
in a named profile that Joho
remembers from one session to the next.
Joho supports up to
100 named profiles. |UP
TO TOP|
Q:
What kinds of information can Joho display?
A:
Joho
displays two- and three-dimensional grids of numerical information.
The values in the grid cells must all measure the same quantity.
This is similar to the restriction of a graph where each point in
the graph is measuring the same quantity as shown on the Y-axis. The
sameness of the cells is the only restriction.
The actual meaning of the cell values is arbitrary, and contained
in the labels and other annotations. The examples on this web site show
some of Joho’s flexibility. |UP
TO TOP|
Q:
Can you read numerical values from a Joho image?
A:
Clicking any cell in the image displays the column, row, and level
locations and labels, a cell label, and the cell value.
|UP TO TOP|
Q:
Can I change the layout of Joho images?
A:
Joho
displays matrix files using a small text display script.
By default, the layout is retrieved from the current project
profile. The user adjusts
the layout (image size, legend position, title positions and fonts,
etc.) by dragging the components on a layout template screen.
Changes in the current layout template show up whenever Joho
displays an image, and are stored permanently in the named profile for
future use.
|UP TO TOP|
Joho
supports up to 100 named profiles. This makes it possible to have
different layouts for different projects.
Once an image layout
is defined, the user can make the display script permanent so that
further changes to the profile will not affect that version of the
displayed image.
Q:
Can I create my own color palettes for Joho images?
