Module:Sandbox/Mathglot/Xreadership
 | This module is rated as alpha. It is ready for limited use and third-party feedback. It may be used on a small number of pages, but should be monitored closely. Suggestions for new features or adjustments to input and output are welcome. |
This experimental template is designed as a stopgap replacement for {{annual readership}}, which is currently nonfunctional due to depending on the Graph extension, which was deprecated due to a security issue. It generates a bar chart showing page views for a given period (default: three months) from a downloaded pageviews file. The chart is in a box with a heading, and may be placed on an article's talk page below other talk page banners. See § Notes for important technical limitations and other details.
Usage
- {{User:Mathglot/sandbox/Templates/Xreadership}}
- {{User:Mathglot/sandbox/Templates/Xreadership|days}}
Parameters
There are three optional parameters:
|1=– the count of page view bars to display (optional; alias:|days=; default: 7}};) Large values may cause failure, see § Notes.|2=– the pageviews file. (Default: {{TALKPAGENAME}}/pageviews.) See § Instructions. (not implemented yet)|expanded=– if non-empty, chart is expanded by default. (not recommended)
Categorization
Pages with this template are categorized in Category:Pages with experimental page views chart enabled as long as the pageviews data is not stale. When the pageviews data are aging ((i.e, age > 7 days) it is added to Category:Pages with experimental page views chart needing update, and after the pageviews data becomes stale (i.e, age > 30 days), the article is moved from the aging category to Category:Pages with stale experimental page views chart.
Once the pageviews file is updated, it is moved back to the first category again, and removed from aging and stale. See § Maintenance.
Instructions
How-to
Displaying an experimental pageviews bar chart for a given article involves these steps:
- add User:Mathglot/sandbox/Templates/Xreadership to the Talk page below the rest of the banners; hit Preview, and click [show].
- open tabs for the /pageviews page (edit it if blue), and for the pageviews tool
- download the pageviews data from the tool (three months's worth recommended) and copy it to the open
/pageviewstab (overwriting any former data), but do not save it yet; - test in Preview mode (important!). If there are problems, replace the call with {{User:Mathglot/sandbox/Templates/Xreadership|days=45}} and preview again. Publish when the bar chart *and* the rest of the page are displayed properly.
- Optional: to view as much pageviews data as possible without blowing up the rest of the page, fine tune the value of
|days=to keep template usage high, but within bounds; i.e. PEIS below 2Mb; 1.7 is better. Be aware that if someone later adds complex templates in a discussion, they may not work if insufficient resources are left after the chart; keep the page on your watchlist and monitor changes.
Pageviews file
This template requires a pageviews file in CSV format, which by default is expected to be available as a subpage of the article Talk page where the template is placed. Positional param 1 is available as an override, to point somewhere else. The pageviews file may be placed by bot, or manually by an editor.
Contents of the pageviews file may be downloaded manually from the pageviews tool. Request output in CSV format, and copy it to a Talk subpage whose subpagename is pageviews; e.g., Talk:Cleopatra/pageviews. A good amount of data to request is three months' worth. Any amount of data may be copied to the subpage, but the template will only display at most the last 150 lines in the file to avoid issues caused by technical limitations with templates.The template has to read the whole pageviews file even if less data is displayed, and long files may exceed some technical limitations and cause the template to fail; reducing the pageviews file size may permit more of it to be displayed, than when the total filesize is larger. Empirically, the optimal amount appears to be 60 or 75 days, for Talk pages with an average number of other templates on them. Some pages will show 90 days, or even more. However much data is downloaded to the file, you may always display less than the full amount using param |days= in order to avoid exceeding template limits.
Maintenance
If the pageviews file is not updated, it will eventually reach the staleness threshold (currently, 30 days) and after that will not be displayed. To display it again, repeat download step 1 above. You may download and save the pageviews file for a given page as often as you like; just save it on top of the old one. To make it easier to know when maintenance is necessary, the summary view of the collapsed Talk page chart banner displays the age of the file in days: the day you download it, it will show "age=1", meaning you have pageview data through yesterday. This value will grow if the pageviews file is not updated, until it hits 30, and then the template will show a prompt message instead of the bar chart.
Modifying the display
Vertical bars
See parameter |mode= to cause the chart to display vertical bars.
Hiding the template
A registered user who prefers not to see this template on any talk page, may hide it from view. You'll need to have an account to do this. Note that this procedure applies to Talk page banner template User:Mathglot/sandbox/Templates/Xreadership only; charts on pages that call the User:Mathglot/sandbox/Templates/Xviews chart generator template directly are not hidden by this procedure:
- Edit your user style page at Special:Mypage/common.css.
- Add the line:
.box-Xreadership {display:none;}to your common.css file. - Save the change.
- Follow the instructions for bypassing your cache.
When you refresh or load a page that has the User:Mathglot/sandbox/Templates/Xreadership template on it after completing the procedure, it should no longer be visible on the page.
Examples
Because of the nature of the template, any examples placed here may become stale over time if they are not updated. Instead, view live examples by finding the Talk pages having the most recently updated pageviews files, and go to the Talk page parent of the subpage to find the Xreadership invocation and see this template in operation. It is usually located towards the end of the Talk page headers at the top of the page. The most recent pageviews file update is this one.
Notes
This template is a mockup of a replacement for the non-working {{annual readership}} based on {{Graph:Chart}} which was withdrawn for security reasons. It is a proof of concept and if approved, is designed to be replaced by a Lua module, until it reaches end-of-life with a permanent replacement for the Graphs extension.
Technical limitations
There are various limitations in the template which will disappear in a Lua version, such as reaching the PEIS limit if too many statistics are charted at once. The default value of param |days= is a throttle to help avoid this. If there are a lot of other templates on the page, you may need do reduce the value of that parameter to stay within limits. See Help:Template limits.
Troubleshooting
- Chart does not display – some cases are recognized by the template and trapped with an error message; others are not.
- recognized errors:
- missing file – if the pageviews file is missing, you should see a red error message.
- stale data – if the data in the pageviews file is older than the 'stale' age, then a message about stale data should be emitted.
- unrecognized:
- template limits exceeded – if there is no chart and no error message, you may have exceeded one of the template limits. In this case, you may see just the template name instead of any output; this is a sign that PEIS has been exceeded. Try running it in preview mode; if PEIS is exceeded, you may see the message, Warning: Post-expand include size is too large. Some templates will not be included. in a pink box at the top, and the parser profiling data will show the PEIS maxed out at "2,097,152 of 2,097,152 bytes". If you see that, try reducing the value of
|days=until it shows output in preview mode, then save it. Reducing the pagefile size will also help; the template reads and processes all the data (multiple times, which a module won't), and if your pagefile has a year's worth of data, you may only be able to display 30 days of it, whereas if you reduce it to three months of data, you can probably display all of it.
Known issues
- Wrapping – in some cases, the page views in the right margin wraps to the next line; this usually only happens with the longest bar in the chart, and especially when the values are greater than 1,000 (and thus require 4 or more characters)
- length of longest bar – by design, the bar representing the page view statistic with the highest value should be close to the right margin (allowing space for date on the left and view statistic on the right); all other bars are positioned as a fraction of the longest one. Currently, the longest bar will display close to the right margin if all data in the pageviews file is displayed, but if less than all data is displayed (due to use of
|days=or default value) and the largest value in the pageviews file happens to belong to a non-displayed statistic (i.e., one more than three months ago, in the default chart), then it's possible that the displayed bars will appear shorter, as they are still displayed relative to the largest page view statistic in the file, even if it is not displayed. The fix is to display the longest *displayed* statistic close to the right margin, and other bars proportional to it. In practice, this means an adjustment to User:Mathglot/sandbox/Templates/Xviews/max views to return the value of the largest displayed statistic, not the largest one in the pageviews file. - x-axis caption – missing the namespace.
- Others: see Talk.
Phase-out upon replacement of Graphs extension
This template should reach end-of-life after the Graphs extension is reenabled or replaced. This was initially envisaged for May 2025 at English Wikipedia. The new Charts extension was initially enabled at several Wikipedias, and since June 2025 is available on all Wikipedias. Unlike the Graphs extension, the new Charts extension was redesigned from the ground up with chart data required on Wikimedia Commons, and so a simple redirect of template {{annual readership}} or User:Mathglot/sandbox/Templates/Xreadership to a new template will not work. This may result in an overlap in the use of User:Mathglot/sandbox/Templates/Xreadership with the new extension until backing data and other requirements are satisfied at individual pages that invoke this template.
