Vertical Axis on Small Quantities #128

Open OpenOilUG opened 2 years ago

OpenOilUG commented 2 years ago

GEM Review: 10.12.21 "Problems with vertical axis labels: For countries with very small production, the vertical axis labels have problems. For example, for Slovakia’s gas production, the axis labels all say “0.” For Slovakia’s oil production, the labels are: 0, 1, 1, 2, 2, 3, 3, … So it seems that it is actually showing values of 0, 0.5, 1.0, 1.5, 2.0, 2.5, … but the values are being rounded off for presentation in the graph. Also there are issues with the scale shown. The values often go above the highest value shown on the scale (for example, see Slovakia’s gas reserves. The maximum value included in the vertical axis should be higher than the maximum value in the data, to ensure that values displayed can be appropriately read off, and so that the graphed lines don’t butt up against the top of the display area. In the case of Slovakia’s gas reserves, for example, it might not be clear to a user whether the flat green line across the top of the graph is a plot of data points, or something else."

So, the obvious option would seem to be to relativise the Y axis against maximum amounts and then adjust Y axis scale dynamically to represent appropriate granularity.

Moving back to backlog list (17.5.22) since example of Slovakia https://dev.fossilfuelregistry.org/co2-forecast/sk?productionSourceId=2&reservesSourceId=2&gwp=GWP100&projectionSourceId=102 shows not resolved.
