Bjorn,  I am really glad that this function has found its way into the chart in
a more serious way

Please look at my comments from 26 September for general thoughts.  While some
of  the suggested features are perhaps a bit ambitious I do think that the
polynomial fit is essential, please make sure it makes it on to the road map
even if it needs to wait for a later release

jimplante: linest function won't generate correct regression equation. For same
data values I get y=281.7812 x + 79.1733 value from oo.o 2, but excell's
equation is y = 0.0368x - 0.0935. 

It's not linest works differently on excell (same formule in excell's cell gives
same regression equation as oo.o), but problem is drawing of regression line for
oo.o. Linest are different for excell and oo.o as well. Excell's regression line
is much more accurate than oo.o's regression line. 

So it's not only calculation also problem relies on oo.o's regression line
drawing as well.

I'm sorry you developers got flamed by people who profess to study statistics 
and who don't appear 
know how to substitute the slope and intercept into Y=mX+b in a text cell to 
one side of the graph. 
Hell, it can even be automated to a certain extent using the text, slope, and 
intercept functions already 
in Calc. Like so: ="Y=" & ROUND(SLOPE(A2:A22;B2:B22),2) & " X + " & 
ROUND(INTERCEPT(A2:A22;B2:B22),2). For R^2, use this: ="R-square 
="&ROUND(INDEX(LINEST(A2:A22;B2:B22;1;1);3;1);2)

For me, that equation box would be nice to have, but it's not a deal killer. 
Seems to me that there are a 
few scientists commenting here who need to broaden their horizons and learn to 
use the rest of their 
spreadsheet formulas.

But, as others have said, I'd like to have the means to display more than one 
regression line on the 
graph.

Just looked at the new charts in ooo2.3, much better, good job guys.

Now some thoughts on trend line plots and equations, I hate to say it but excel
functionality is a very good place to start although there is more it could do.

Key for me that is missing altogether in ooo is polynomial fit, I use it a lot!
 It would also be very good to be able to user define an arbitrary form of the
equation to fit to.

In addition to printing the equation on the chart it would be extremely useful
to be able to output the co-efficients to cells in the worksheet so that they
can be used directly elsewhere.

Finally if the chart module ever supports plotting surfaces (is there an issue
for this request?) then extend the trend line plots to cover that case as well
although I do understand that this is a rather more difficult problem.

A final thought, please don't look at excel and think that that is enough,
always strive to make ooo better and offer that extra bit that excel is never
likely to have but can make all the difference to certain users

@bm

First of all, thanks for working on this issue. :-)

>1. OOo is for free, it is open-source. Everybody can participate in its
>development. I admit that getting started with OOo development is not easy, but
>it is possible, and there have been patch submissions for bugs and features in

>(according to those people).

The fact that OpenOffice.org is free doesn't count much. SUN decided to
distribute it for free, and it is not a justification for lack of feature or
slow development.

Telling that if nobody added this feature, the feature is not important is not
exact. Many users have not enough knowledge nor time to learn to add features to
OOo, but an expert coder should not have many issues. The algorithms are out
there in all languages, and efficiently implemented in various libraries, among
which there's GSL.

>2. OOo is developed in a community. That means that there is no "us" and 
>"you". 
>"We" do not have the duty to do anything "you" want. "We all" have to work
>together in a constructive way. As long as all the (two) developers for the

>quite high.

There evidently is a "you" (developers) and a "us" (users). And a lot of OOo
users can't code, but you are right, we should work together. To do this
however, it is necessary to communicate. And if it's true no one suggested how
to implement this feature, no one asked for ideas and tried to communicate with
users' community, so the responsibility is on both sides.

I can understand that SUN influence is high, but if they ignored the chart
module for such a long time, they clearly have some issues in their decision
process. Just consider these two points:

- The XY plot is the most used in schools, and in a XY plot usually sets have
different number of elements. Trend lines and error bars are widely used too.
The lack of these functionalities directly excluded OOo from the adoption in
schools and universities, but also in labs and scientific institutes.

- Having functionalities required in schools is having a product which probably
will be adopted on a wider scale, because if people use it at school, they will
use it for their work too.

>3. Most of the people in the world are not scientists. Most of the people
>working with OOo don't know what a regression curve is. Even more people don't

Right. But most people go to school. Most people, at least once in their life
plays with plots, curves, analytical geometry, experimental data. It's quite
common to do lab experiments in high school for example, and to have to process
small amount of data, plot them to compare their trends and so on. A good
spreadsheet can be used in various ways for educational purposes.

With kind regards.

I am currently working on this feature, so I browsed through the huge number of
comments in this issue. It is really amazing that there is not a SINGLE useful
hint about how to implement this. Well, one statement talks about a check-box,
yes that's a start.

This issue also sometimes make me think that I should close it an open a new
one. There are two people working on a complete re-write of a module which took
very look, admittedly, but which was necessary to do this feature. Obvisouly it
is hard to understand, that first things have to come first.  Instead people are
ranting about ignoring users. Just want to remind everybody:

1. OOo is for free, it is open-source. Everybody can participate in its
development. I admit that getting started with OOo development is not easy, but
it is possible, and there have been patch submissions for bugs and features in
the chart already. And nobody who wrote anything into this issue can blame us
for not dealing with this feature for five years. If this was important to you,
you would have had five years to implement this yourself. Should be no problem
(according to those people).

2. OOo is developed in a community. That means that there is no "us" and "you".
"We" do not have the duty to do anything "you" want. "We all" have to work
together in a constructive way. As long as all the (two) developers for the
chart are payed by Sun Microsystems, it should also be clear that the influence
of this company to decide what features are implemented in which order, is quite
high.

3. Most of the people in the world are not scientists. Most of the people
working with OOo don't know what a regression curve is. Even more people don't
know what R^2 is. Just keep this in mind, when thinking about priorities of
features.

->tonygalmiche: Thanks tony for you help with the specification, which actually
is a competetive analysis to Excel.  I am not sure if it is wise to always just
copy Excel, but it gives ideas of how other people do it at least.

R^2 is the value of interest. R^1 would be the square root of R^2, you can
calculate that yourself, and why would you want to compare those values? The
only additional information of R would be a sign, but is that really relevant?

BTW., R^1 is what you get from the API function
XRegressionCurveCalculator::getCorrelationCoefficient(), so you can get this via
a Basic macro.

Currently, there seems to be a quite easy enhancement at hand: we could show the
regression formula and the R^2 value in the quick help and the status bar for a
selected curve. This, howevver, does not help for print-outs or copying the
formula to the clipboard. See Issue 78442 for this enhancement. There is a
screen shot attached to show how it looks like.

That is very good and accuratelly brought under words.

Plus that it is possible to tell the regression line to go through the point 
where the two axes of a graph cut eachother. I think it's called origin, not 
sure because English isn't my native language.


(in my last post: I meant like in MS excel not in MS word)

I'd like to suggest that when regressions are performed, a new sheet (possibly 
named "regression data" could be automatically added to the file that states 
the worksheet/chart/data series the regression is performed on as well as the 
regression type, regression constants, and R^2 value.  Each new regression that 
is performed could add a new section to the "regressions sheet".  If a 
regression is deleted from a chart, its corresponding information on 
the "regressions sheet" should also be deleted.  This should mitigate most or 
all of iha's comments from Fri Nov 24 15:23:24 + 2006 in Issue 7998.  While 
it falls short of the ideal solution in which these values are displayed on the 
chart, it would at least be a major step in the right direction.

In an equalation of the regression line please make them movable and also an R 
and R^2 that shows how close the regression line is to the data pointed out. 
Also option to make the regression line start on zero like in word would be 
much appreciated.

I think one could go even further : if OpenOffice could integrate (or serve as a
graphical frontend and data supplier) with an opensource statistical packeg such
as "R", many scientists would rapidly choose OO over MS Office

This is a show stopper for me.  When this is fixed I will be one step closer to
uninstalling MSO.  If OOo were to one-up MS Excel on this feature and improve
the flexibility and functionality of regression curves and equations, the
science and engineering community would have reason to choose Open Office OVER
MS Excel.

I have to agree.  5 years is a rather poor response to a sensible request, and
to 44 votes.  Oh, and there are another 46 votes on 5289 as well, reading which
suggests that it is still not in the new chart module.

Look lads, much as I like the product, I need to do this.  It matters.

The equation for linear regression is available somewhere because it was used
for drawing the regression line... 

What a shame it is currently impossible to see the equation parameters... The
tool I use for getting the equation is called Bill's Excel, by Bill Gates. Oh 
joy!

Guess what, guys?  You've alienated an entire community by dropping the ball on 
this mod for nigh on 
*five* years.  I'm a scientist who was until now interested in participating in 
the open-source revolution.  
However, the lack of this essential functionality cripples this application for 
anyone doing graphical (read 
scientific) data analysis.  Please get to it sometime soon.  It can't be that 
hard to display the equation of 
the line if the application is computing the damn line anyway.  If Microsoft 
can do it

Please get to this.

This feature has been requested many times (since OOo 1.0.1!) because it is
really necessary both for compatibility with Excel, and also to increase the
adoption of OpenOffice.org.

Actually I was expecting this feature to be included in the new Chart module by
default, considering how many times it was requested, but I understand it's not
easy to implement it.

However I'd really prefer to see even an ugly temporary solution instead of
nothing. I work on Linux and each time I've to do regressions, I have to switch
to grace to do them, with a significant time loss.

I really don't understand why it wasn't added before by companies which develop
a personalised edition of OOo like Novell. Maybe some help could come from them.

So...my votes to this request with the hope to see it soon implemented ;-)

I don't expect that adding this feature would be easy, otherwise I'm sure it

lot of people.  iha, would you be willing to set a target milestone for this

That is no solution, as more than one regression curve could be generated.

Displaying the equation should not be a problem : it could just be inserted as a
subtitle. And as the subtitle is just a textbox, it can be moved around, the
font can be changed etc. 
By the way, even more professional statistic programs use the subtitle to insert
the regression equation, significance levels and R2.

Sorry a checkbox alone does not do anything. The regression parameters have to
be displayed. When they should be displayed in the chart the layout automatism
must reserve the correct place for it. And maybe you want to be able to indicate
a number formatter for the variables and want to be able to manipulate the text
properties like font etc. Move that thing around in the chart. This all needs
then to be saved thus we need to extend the fileformat.

Also coming  from the scientific community I have to say that I agree with all
of the users comments on this issue. It is unacceptable to be able to calculate
a regression (even logarithmic etc) and not even show the equation that goes
with it. As the equation has been calculated to estimate the fit, the data is
availabe, so it's just a case of adding a button "Show regression equation" and
then add a text field with the equation. This is probably a lot less difficult
than redesigning the whole thing and adding bells and whistles of exotic
options. When I talk to colleagues about using OO, they just laugh and say "
have you had a look at the graphics capabilities. We'll have a look in another
10 years"
