# Known limits

What Fude does not do yet. Each is a good first issue to open.

* **Two y axes.** A chart has one y scale. Two measures of different
  scales are two charts, or small multiples.
* **Times are in UTC.** Times are drawn and written in UTC; a time zone
  for the chart is to come.
* **Maps.** The world and the US states; street maps with tiles are an
  add-on to come. Points at a longitude and a latitude are to come.
* **The server's SVG.** The SVG and PNG files are made in the browser. A
  chart as SVG on the server (for an email or a PDF, with no browser) is
  to come.
* **Appending** suits charts whose marks are their rows.
* **Small multiples of a query** read the query's rows, not its groups.
* **The table of a streamed chart** is the one of the last render.
* **Brushing and zooming** a range of a chart is to come.
* **Messages.** The few words that Fude writes itself ("Data", "Total",
  the descriptions) are in English.
