bug fix: the color scale should remain fixed for the whole set to allow easier comparison between years (phab ticket), or the color should show rank ("global position") instead of percentage
bug fix: if increase is > 100%, black is currently shown
default have colors go from for example blue to red for low to high rather than just a blue scale (phab ticket)
@Doc James: This is set by the ["#01f1f0", "#08306b"] bit in Template:Global Heat Maps by Year. (Replacing it with, for example, ["orange", "green"] would switch to orange-green scales.) Could be set to have different defaults and/or allow specific colors through a parameter (maybe min-color= / max-color=, or something). --Yair rand (talk) 21:36, 12 January 2020 (UTC)
User:Yair rand it would be cool if users could select the color range that they wish when using the template parameters :-) Is it possible to use "# redyellowblue"[3]Doc James (talk · contribs · email) 10:56, 13 January 2020 (UTC)
Much better, but the diff scale is much more clear than the absolute scale. Is quantization necessary? It reduces the number of discernable shades. Also, non-uniform distribution sometimes makes the data differences hard to see. Sometimes there may be a logarithmic distribution of the data. One approach would be to index the values, with colour 1 representing the lowest value in the full matrix, 2=the second lowest, up to <number of years>*<number of countries> for the highest value. That would also solve bug fix no 1 above - to make the color scale fixed for all years.Tomastvivlaren (talk) 16:46, 25 March 2020 (UTC)
allow the ability to zoom or to just show specific regions of the world (like Asia, Europe, North America, South America) similar to the tool here https://sdg-tracker.org/no-poverty (phab ticket)
allow the ability to filter on various wikidata properties
Is to use WP:VideoWiki. Basically download each year as a .png and stitch them together. Will keep the easy updating as new years come out. A little harder to get them going though. And not as dynamic for our readers.

Have now filled in zero for all the years and it fixes it a bit. Doc James (talk · contribs · email) 18:22, 17 November 2019 (UTC)
When one looks at the difference between two points in time for a country were no data is avaliable it gives a value but shouldn't Doc James (talk · contribs · email) 18:24, 17 November 2019 (UTC)
Age-standardized death rate from cancer per 10,000 people.[9]
The percent sign comes from the line in Template:Global Heat Maps by Year beginning with {"template": "{{{columnName}}}:, at the end. You could replace the "%" with something like "{{{%|%}}}" to allow |%= to hide the symbol. --Yair rand (talk) 17:28, 6 October 2019 (UTC)
