The spec [19.15] does say: "Additional chart types may be supported by using a different namespace." But I'm not sure what that really means. Are there examples of this already? There are standard namespace aliases in ODF, like text: or style:. You can use loext: as a namespace that is intentionally not in the official spec but is an LO extension. See here for more info: https://wiki.documentfoundation.org/Development/ODF_Implementer_Notes > - I made various UI choices that may not be best. For instance, I added pie-of-pie and bar-of-pie as subtypes of pie in the chart selection matrix (widening it to 6 columns). It might be preferable to keep of-pie as a different chart type (adding a row instead of two columns). I also made arbitrary decisions about sizes and separation of the two chart parts in the rendering. It appears there's a UI group that meets. Are these choices the kind of things that could be put on their agenda? Heiko leads that, and you can just mail design@xxxxxxxxxxxxxxxxxxxxxx if you want design input, see: https://www.libreoffice.org/get-help/mailing-lists/ > - In the selection matrix mentioned above I added crude placeholder graphics that I created just by taking a screenshot of representative of-pie charts. But they look nothing like the graphics for the other chart types. Is there some prescribed process (or person) for creating uniform-looking UI graphics? One way that works is to put a placeholder image (so you can test your code) and then ask for help on the design@ list. I did something like that myself in the past. Regards, Miklos
