Template:Medical cases chart/doc

Description
This template should be used for all outbreak, epidemic and pandemic medical cases charts based on Bar box to maintain consistency. It displays horizontal bars for up to 5 different classifications of cases for each valid date or interval. It offers two columns to make numbers explicit and to show relative or absolute changes. It also uses a sophisticated toggling system to control the visualization of data rows across many months or years. It is designed to be flexible, but still standardizes some parts of the chart. This template should be transcluded in other templates, NOT in article pages. Suggest features in the talk page or code them if they're neither controversial nor incompatibility prone.

It may be desirable to make a specific outbreak chart have different widths depending on the page it is displayed. The  parameter can be used to achieve this. For example, barwidth will display the chart wide in the template page itself, but will allow different widths when the outbreak template is transcluded with this parameter in article pages.

is a sequence of the initials of none, thin, medium, wide, extra wide and default, and it determines the maximum width of each number in the data columns. Therefore, one should be chosen that minimizes the total width, but which doesn't make the numbers break/wrap on mobile view. Using 2 or 4 characters allocates one or two data columns, respectively. For example, mw sets the right1 value column to medium and the right1 change column to wide. mwnt sets the right1 value column to medium, the right1 change column to wide, the right2 value column to none, and the right2 change column to thin.

The navbar links are constructed like this: " data/   /  /   medical cases chart". may be more descriptive than  to avoid page name collisions. So, for example, COVID-19 charts have COVID-19 pandemic. has "the " internally removed and is capitalized to become.

By default, the "Last X days" button toggles days which intersect with those of the last months. This happens regardless of the state (activated or not) of the month buttons. In fact, due to limitations of custom collapsing, toggles are stateless (a workaround is used to simulate two 'states'). All in all, this can lead to situations where clicking one button causes unintuitive toggling like creating date gaps. works around this issue by forcing the buttons of the last months to not overlap with the "Last X days" button. The result is usually a partial last month button, "Mon XX-XX", where XX are the first and last days of the month that the button affects. Extra info in the main bug discussion.

To display absolute change in the first column and percent change in the second column, set the following (AA represents any two allowed characters, # represents the classification number being shown, which should be the same for  and  ):

|numwidth=AAnw |right1data=# |changetype1=a |right2data=# |changetype2=o

Data
The  parameter should be populated by a sequence of lines containing a different set of parameters separated by semicolons,.

All values are optional, and empty values can be represented by sequential semicolons (e.g. ). Omitting the date will treat the row as a date interval, unless the date can be automatically interpolated (for 1 day intervals). This is mostly done when no new cases are reported. Omitting a classification value makes a 0 width stacked bar and omitting all values or the line itself is recommended to depict dates where no data is reported.

The expression for total in the 3rd cases classification has deaths and recoveries automatically subtracted from it. If a manual calculation of the number in that classification (generally active cases) is wanted, use. The same applies to the expression for total in the 5th cases classification and.

The,  ,  , and   values can be automatically calculated if omitted. The 1st column values will be automatically calculated if  is omitted or # of cases, and the 2nd column values will be automatically calculated if # of deaths. If  or   are set to other values, the columns can still be automatically calculated by setting   and   to the classification number wanted for display in columns 1 and 2, respectively (e.g.   for deaths,   for recoveries,   for total, etc.). The changes in the first and second columns are automatically wrapped in parentheses.

The  can be any number of the parameters below and their values, separated by semicolons. See the examples.

alttot1   = alternate expression for active cases (3rd cases classification) alttot2   = alternate expression for number in the 5th cases classification firstright1= whether a change in the first column is not applicable (n.a.) (yesno) firstright2= whether a change in the second column is not applicable (n.a.) (yesno) enddate   = end date of interval if automatic one causes incorrect toggling behavior [required if chart ends with interval] note0     = note text post-fixed to the date, that should create a minimum space consuming object, like a note link, to avoid wrapping note1     = like note0, only post-fixed to column 1 note2     = like note1, only post-fixed to column 2
