Allow overriding of Radar Chart min/max values for tick calculation
In cases where the possible minimum/maximum values are known in advance, it should be possible to use these to determine the starting/ending ticks of Radar Charts. This would allow stable and comparable charts across disparate data sets.
Currently, the tick spacing and the supporting titles are calculated by taking the minimum and maximum data entry values, which is fine for the general case, but makes it hard to compare datasets against absolute margins, as the ticks change position according to the entries.
A workaround is to create a transparent RadarDataSet with a maximum value.
RadarDataSet(
entryRadius: 4,
fillColor: color.primary.withOpacity(0.5),
borderColor: color.primary,
dataEntries: [
RadarEntry(value: aiScoreState.accuracy),
RadarEntry(value: aiScoreState.angle),
RadarEntry(value: aiScoreState.balance),
RadarEntry(value: aiScoreState.inertia),
RadarEntry(value: aiScoreState.moment),
],
),
// max val
RadarDataSet(
entryRadius: 4,
fillColor: Colors.transparent,
borderColor: Colors.transparent,
dataEntries: [
RadarEntry(value: 1),
RadarEntry(value: 1),
RadarEntry(value: 1),
RadarEntry(value: 1),
RadarEntry(value: 1),
],
),
This workaround does not work in my case: I have values ranged from 0 to 2000, but i'd like to 'group' all the values below 800 to 0. So basically my range is [0; 2000] and i want to cast it to [800; 2000] where 800 is the first drawn tick, and values below that should be set to 0 or drawn between 0 and the first tick
Seems this can't be done for the moment
What about overriding the <800 data points to zero before you pass them to the chart for drawing?
I tried that but then other values, such as 800.0 won't be on the first tick, because this will re-distribute all the values between [0-2000], so the value 800 would be almost on the central tick insead of the first tick
