Tabs do not work in PlotData
"^ (caret) in texts means: tab" does not work, as seen. Den fjättrade ankan 03:15, 19 Jun 2004 (UTC) at:1719 shift:($dx,0)   text:^^ Interregnum

Reply: Tabs are only used in TextData, see.

In PlotData you can shift texts to the right by adding spaces (put double quotes around text).

at:1719 shift:($dx,0)   text:"                  Interregnum "

But a better way is to add a shift value,

at:1719 shift:(130,0) text: Interregnum

As far as the layout is concerned, this makes the picture much wider, why not use a linebreak and shift the text slighty upwards? Erik Zachte 11:55, Jun 19, 2004 (UTC) from:start till:1720 shift:($dx,5)  text:" Ulrika Eleonora ~ Interregnum "

Answer to remarks on sv:Användardiskussion:Den fjättrade ankan
I find it quite easy to use the EasyTimeline Syntax. But there is a few things that does not work:
 * The character å does not work, as seen at sv:Sveriges historia: Tidsaxel, for example at 1974: 1974 års regeringform.
 * > I use Ploticus for the actual rendering. It has a built in font with an unusual set of characters. See the table at, bottom of page. Unfortunately no å. Ploticus does support unicode and user defined fonts, and I certainly want to support that as well, but that may take some time, I can't test it myself, no Linux here (it works with freetype, which is not part of the Windows build of Ploticus which with I can test offline). So I will have to ask someone to help with this.
 * >In the meantime you might use an alternate for display without the å like alternate text


 * The id: for colors= does only work sometimes. I have tried to set id:Krig (=war) and color:Krig with red color at sv:Mall:Tidsaxel stormaktstiden, but it only works at one place from, 1632-1648, althuogh I had set it to 1630-1648... At other times (1611-1613), (1675-1979) and (1700-1718) it does not work.
 * > Look again, you have defined overlapping periods. For example:

from:1611 till:1613  color:Krig text:.. from:1611 till:1632  color:Vasa text:.. So the last bar overwrites the first. Den fjättrade ankan 01:36, 21 Jun 2004 (UTC)
 * It would be nice to have DateFormat = dd/mm/yyyy work from at least 1500, not only from 1800.
 * > I am afraid this is not possible. Ploticus uses an internal date/time format in which 01/01/1800 is zero. Many programming languages have a similar internal representation. Of course this could have been implemented otherwise, but I assume in the seven years Ploticus exists noone used it for historical timelines, it is often used for scientific plots. Maybe I can ask Steve Grubb to look at, but even if he wants to modify this it will not be soon, new releases are some half year apart. Erik Zachte 03:46, Jun 21, 2004 (UTC)

Example of define
the given example Define $broad      = width:10 Define $narrow     = width:30 Define $bardefaults = $broad fontsize:S is not intuitive. Why is the value of $broad defined as 10, but $narrow is set much bigger. Is this a joke or am I misunderstanding how "width:" works? --141.53.194.251 08:45, 2 Jul 2004 (UTC)
 * Oops. I'll correct this. Erik Zachte 19:51, Jul 2, 2004 (UTC)

Vertical down?
Is it possible to make a vertical timeline that goes from TOP to BOTTOM? That is, say, having 2001 at the top and 2004 at the bottom, instead of 2001 at the bottom and 2004 at the top? --24.74.121.185 01:55, 11 Aug 2004 (UTC)


 * Yes, add 'order:reverse' to TimeAxis command. This is not documented yet on meta syntax page, many script syntax enhancements aren't. It will be done in due time, but I have several other Wikipedia projects that need attention first, sorry. Erik Zachte 05:29, Aug 11, 2004 (UTC)


 * Unfortunately, it only works with DateFormat yyyy. My plans to create a timeline of the hurricane season will have to wait. :( --24.74.46.255 05:00, 24 September 2005 (UTC) (Golbez on en)

Nifty Features Should Include Applicability Notice
Readily discerning whether a nifty feature doesn't work on one's personal wiki because the configuration is wrong or because that feature is implemented in a newer version of MediaWiki would be a good thing.

For instance, EasyTimeline appears to be a new feature in 1.3. . But what is not clear is exactly when it was added. Should I expect it to be present on my 1.2.6 site? Will I get this feature if I upgrade to 1.3.2? And then, in the future, if this feature is removed, in what version will that change of state occur?

Complex features with many sub-parts should probably indicate when the sub-parts were added and removed.


 * Agree, but this is not the most likely page to be read by the persons involved. You might try a post at e.g. the Village Pump, or the wikitech mailing list. Erik Zachte 22:32, Sep 16, 2004 (UTC)

Adding EasyTimeline
Hi, I am running a MediaWiki-based Wiki about History. How can I add Timeline functionality? I cannot manage to make timelines!


 * I'll post instructions about this in the coming days, probably Friday. Erik Zachte 10:12, Dec 1, 2004 (UTC)

Timelines and Templates
Is there some hope for template-based timelines, which would allow using in the timeline (like Colors = id:XX   value:  )? --Glimz 15:59, Jan 24, 2005 (UTC)

New Feature Request for ScaleMajor
Could you add an additional optional parameter, maybe called "End", that would stop the scale labeling, similar to how "Start" delays the labeling on the scale? --65.28.5.69 22:41, 12 May 2005 (UTC)
 * I'll put it on the todo list Erik Zachte 09:10, May 14, 2005 (UTC)

Rendering Change Request for PlotData
When the 'till' parameter of a bar excedes the scale, currently an error is generated. Could instead, maybe just a warning be generated and the table be rendered, just like 'till:end'? Maybe even add an indication in the table that shows the bar would continue off the scale (like an arrow). Our scales are constantly changing and updating the 'till' parameters take a lot. --65.28.5.69 22:41, 12 May 2005 (UTC)
 * Can you show me an example of scales that are constantly changing? Erik Zachte 09:10, May 14, 2005 (UTC)
 * We have a lot of timelines of composers. Sometimes the Medieval era timeline will end at 1400, sometimes at 1450.  We have changed it 3 times so far.  (I guess that's not constant.)  A person who died in 1420, for exampe, is the problem.  If the ScaleMajor goes to 1400, we use a bar with till:end.  If scaleMajor ends at 1450, we change the bar to till:1420. If we could leave it always at till:1420 and the rendering figures out to stop at 1400 if that is where the scaleMajor ends, that would be great.  Am I being clear?  This lets us focus on different sections of the barSet without re-editing all the bar data. --65.28.5.69 03:28, 15 May 2005 (UTC)
 * OK, got it. I hope to start working on ET again within a few weeks. Erik Zachte 09:57, May 15, 2005 (UTC)

Dead link for Measurements
The Measurements link inside the TextData section for the pos operator is a dead link.

Lines connecting points on two bars?
Is it possible to create a line between points on two bars, specified as times?

For example, to draw a line from the 1920 point on bar A to the 1945 point on bar B, I'd like a syntax something like: LineData = frombar:A from:1920 tillbar:B till:1945

Does this already exist, or would it be easy to add?
 * This variation does not yet exist. I can put it on the todo list, but don't expect it too soon. By the way what would you use it for ? Erik Zachte 00:56, July 22, 2005 (UTC)

NEW PROJECT
Hi, I am compiling a timeline of Australian Prime Ministers, but the first few years saw rapid changes of government, so it is very squashy. I am basing it on the data from []. The timeline is at []. Would anyone like to help (e.g. shift the text to be legible etc.) Thanks! User:Brisvegas 04:39, 15 September 2005 (UTC)

Using the ImageSize auto and barincrement
Hi, I'm just trying to make my first EasyTimeline. I've tried to copy bits from existing timelines, but I haven't seen one that does exactly what I envisage (which possibly means what I envisage is not suitable for EasyTimeline, but rather a plain table or something).

My attempt thus far is at w:User:Pfctdayelise/Template:2006 Australian Open and I'm happy it works how I want. (Nevermind I haven't got all the data filled in yet.) I have this line: But what I really want to do is have. But it won't let me because I have. I have a feeling I am not really using it as it was intended. :)

Having the barincrement statement would be great because then when I put Round 2 next to it, all I need to do is make that barincrement twice as big, offset the things slightly somehow, and then it would emulate this tennis draw (PDF) perfectly.

Any help? I would appreciate comments on my Talk page. TIA, w:User:pfctdayelise 15:22, 17 January 2006 (UTC)

Barset syntax?
found some examples 1 2 utilizing "barset" which it seems gives one the capability to be able to add a "skip", unfortunately I have had trouble applying it, does anyone know the rules / syntax for this? I am trying to place "barset:skip" between sets of data to create a space between columns, for example between B & C. something else seem to cue off the split, but I just haven't worked it out. Any help would be appreciated. -- dwxyzq 22:21, 26 February 2006 (UTC)

Is this what you want to get ?


 * Seems simpler like this (using "from:start till:start" to skip the column, no shift needed, and a single barset used):
 * note that this keeps the right bar right-justified (Alignbars=late) 90.5.254.9 01:12, 14 June 2008 (UTC)

"Clickable maps"
By this I assumed it was meant that you could have a map image as a background and place elements over the top of it. But it seems not, unless I'm missing something...? Any help appreciated. pfctdayelise 14:35, 15 March 2006 (UTC)
 * 'Clickable maps' is a html term, it has nothing to do with geographical maps. You can define clickable regions for any image. In EasyTimeline it is used to make texts in a generated chart (png or gif image) clickable. Erik Zachte 23:45, 15 March 2006 (UTC)

Links don't work
When I try to put links in the plot area, like so:

from:1939 till:1945 color:WWII text: World War II ~1939-1945

it still doesn't become a clickable link to WWII. What do I have to do, so that the links will be clickable? Ludde23 15:01, 17 May 2006 (UTC)

Varying height of marks
I'm using a horizontal time line very similar to the vertical one in Joseph Addison, but some of my text is naturally going to overlap with itself. I can shift the text up so it doesn't interfere, but I would like to extend the mark of the "at" so that it extends up to the text instead of having blank space. Is there any way to accomplish this? My experiments with "width" only seemed to vary the size of the (invisible?) bar, resulting in the same size mark being placed further away from the scale.
 * Please name article where your timeline can be seen Erik Zachte 06:45, 29 May 2006 (UTC)

Link in text drawn incorrectly
In the example below, a link in a bar label is drawn incorrectly. This used to work; perhaps a text measurement bug crept in when the timeline font changed.

A solution is to write Popes of the Western Schism instead of Popes of the Western Schism. Cdlt, VIGNERON 13:44, 26 October 2008 (UTC)

Variable today entry
I want to add a mark into my timeline that will indicate the current day without having to modify it everyday.

Any ideas?

What I am trying to do is show when people will be out of the office nicely.
 * This is not possible. EasyTimeline images ar generated are generated on article save time, and after only loaded from disk, until the script changes and a new image is generated. So no dynamic behaviour like described is possible. Even more, templates are not possible because in the Medaiwiki parser the EasyTimeline exntension is invoked before templates are processed. Erik Zachte 00:06, 17 November 2006 (UTC)

Another thing that I'd like to be able to represent properly is putting in background blocks to indicate weekends and holidays. I tried fudging it using markers but they do not quite line up properly.

HELP! Timeline won't go before 1800
I'm trying to promote List of Justices of the Supreme Court of the United States to feature list status and the timeline will not go before 1800.

BarData = barset:PM

PlotData= width:4 align:left fontsize:S shift:(5,-4) anchor:till barset:PM And here is the error message that I'm getting: EasyTimeline 1.9

Timeline generation failed: 3 errors found

Line 5: Period = from:01/01/1789 till:09/03/2008 - Period attribute 'from' invalid. Specify year >= 1800.

 * If you read Help:EasyTimeline syntax it says date format dd/mm/yyyy and mm/dd/yyyy are only supported to 1800. If you want to use pre 1800 you can only specify in years. I guess you probably need to make a bug report if you want this fixed Nil Einne 13:55, 19 March 2007 (UTC)
