lonchart has now merged with lonstudentassessment.

Changing the names of the status form element from ChartStatus to Status.
Hopefully, this will make it more compatable with lonstatistic's forms.

Removed general functions for downloading and processing of student course
data from lonchart into loncoursedata.  loncoursedata will be usable in
lonstatistics and perhaps lonspreadsheet.

Add some comments in the code.

Fixed two pod lines that didn't wrap properly.

Finished the pod documentation for lonchart.  Also removed a couple of parameters
that were no longer in use.

When pressing the chrt button on the remote is supposed to refresh
the chart with the current options selected.  This works, but there
was a problem if the cache database didn't exist for the course.  Now
that is fixed so that it does both a recalculate chart and a
reset selections.  Entering a chart for a course after the cache data
has expired will display correctly.

Add pod documentation for the all the functions but three.

See bug 218.  I changed the alignment of the column checkboxes to left
justified.  The look is consistent, whereas the center wasn't always the
same above the column.  I also added a note above the data specifing how
to remove columns.  Lastly, the date stamp on the top of the page is
the time of download of data.  If there is no cached time stamp, the
current local time is used.

There was a problem where the offsets of the checkboxs above the columns
were not the same between Mozilla and Netscape.  Mozilla's strayed way
far from their columns.  To remedy this, I put the check boxes and the
column headers into a table.  The current position for the check boxes
is center.  It is almost center in both Netscape and Mozilla, but are definitely
above their respective columns.  Left justified may look better, it puts
the checkbox directly above the first character of the header.  This can
be changed.  I had originally had the checkboxes centered and looks good
someplaces and only ok others.  For now, I left it centered.

Moved date stamp back onto its own line.  In mozilla it overlapped
with the picture in the corner.

This commit fixes the display when the chart button is pressed on the
keypad.  Now it updates as if a refresh chart is pressed.  Also added
another button to the form.  Now there are three primary refresh buttons.
First is Recalculate chart, it doesn't change the settings but does
redownload all the data.  Refresh Chart displays a new chart with using the
same data but based on the current selections.  Reset Selections resets all
the user selections to default and displays a new chart using the cached
data.  Also all the form data is stored.

Changed <pre> tag to be around the entire chart data instead of each line of
the chart.  This reduces the gaps between each line.  Also, this brought
forward a bug which was fixed.  Students with no course data were not being
displayed, but now are.  This bug only occurred with the chaning of pre.

See bug 218.
Lonchart now has the ability to remove columns from the chart.  When the check
box is unchecked and any of the refreshing buttons (not recalculate) are hit,
the column will be gone when the new page appears.  Selecting the column from
the selection box and hitting a refreshing button, the column will reappear
when the new page is displayed.  The recalculate button sets all columns to
appear.  The column selection box is only available when there are columns missing
and only contain the names of missing columns.

See bug 484.  The stopping of the download of students works well now.  These
changes make it so that students who don't have all their information
downloaded do not show up in the chart.  When the list was created in
ProcessClassList, someone could stop it before an updated version could
be created.  This meant that students with no data would show up but have
zeros for all their scores.  Another side effect of the stop button code
is that now a user can hit the form buttons during download without
causing a problem with tieing the hash.

Fixed the problem where the columns didn't line up for sometimes if they
were longer than the headings.  This problem occurred because I forgot
to split on the parts of a problem therefore the calculation for column
width was not including multiple parts.

See bug 218.  The problems in the top level sequence now get a heading for
their column.  Changed the pop order on my artifical stack.

Added a refresh chart button.  This will be used to redisplay the screen
without downloading all the information.  It will be used to update the
chart when selectable items that don't refresh the screen are used.

This commit involves bugs: 522, 484, 497, and 218.

A rework of the internal layout and clean up of code has completely changed
this module internally.  The output is basically the same except that there
are header for the columns.  The headers are the title of the sequence or
page in which the problems reside.  This relates to bug 218.  The width of
the column is now determined by the max of the width of the title and the
number of problems(plus number of correct problems).

This version also displays problems that reside in the top level map.  The
only problem with this currently is that the problems are displayed after
all the sequences that reside in the top sequence have been displayed.  This
also applies to any sequence that contains a mixture of problems and
sequences.  This relates to bugs 522 and 497.  The other current problem is
that the heading is missing for the top level sequence's problem's column.

Lastly, this version contains the ability to stop the download of material
using the browser stop button.  This relates to bug 484.  The ties to the
hash are kept down for writing, and there is a some give for tieing to
a the cached data if another daemon is using it.  This give corresponds
to a total maximum sleep time of three seconds before giving up on tieing
the hash for the current httpd daemon.

Overall, there was a lot of code movement within the module and function
renaming.  Some of the algorithms like tracetable were reworked and
added too.  There is now a test procedure for this module call
lonchart.test_procedure which is kept in doc/homework.

See bugs 484,218 (see below)

This submission is in preparation to handle bug 218.  It incorporates Guy's changes from version 1.41-1.42.

First change-  I moved code and redefined functions.  I changed caching from storing pure html to storing the downloaded data.  This appears to have slowed the loading the html of cached data.  The goal was achieved, which was to produce the same output and format of the data.  The only difference is, now it outputs html using a table for the data instead of trying to format long strings of html.

Second change- I have incorporated the use of the stop button on the browser.  This is part of bug 484.  Now data will be cached up to the press of the stop button.  Any sorting of the data will only work with the downloaded data.  Hitting the recalculate button will cause it to attempt a full download again.

Missing quote marks around hash keys for %name in lonchart::BuildChart after lonnet::get

- reworked some of the cleanup wok fro BUG#480
- should find a section for any real students (usection rework)
- properly handles the results from the name get call

See bug 480.  Forgot the error checking with the new lonnet::dump function.

Updated code to use lonnet::get and lonnet:dump instead of using lonnet::reply to gather the information.  See bug report 480.

Implemented links according to bug 421.
Also, inserted &symbclean on artificially created symb to "de-version"

Fixing the shift space bug

Tried to fix the shifting space in multi-part problems.
Guy should put this version on s10 to check it.

fixed bugs in shifting space:









<F10>:

Added a simple count of solved problems in green color instead of the "!" between sequences and pages (3 digits)
Added a total number of solved problems in blue color at the end of the line (5 digits)




<F12>

Fixed bugs in showing the multi-part questions. (should be tested)

Fixed bug in showing the unattempted problems

1. Works with "Page" as a "Sequence" in counting the maps
2. Solved the "multi-part" questions problem.
3. Solved the "multi-instance" problems.

Prints date on screen, explains symbols

*** empty log message ***

-extra newline

- lastname, firstname

Now does some things that make sense
