I think this has to do with that it infers it as a radial scale, if you add the following to your scale config it shows correctly (as a temporary fix): axis: 'y',

ramazan: {
        axis: 'y',
        display: true,
        title: {
          display: true,
          text: 'Value'
        },
        suggestedMin: -10,
        suggestedMax: 200
      }

Looked in the code, this behaviour is happening because of this method: https://github.com/chartjs/Chart.js/blob/767d64e7a90dbfe94f9c5d159a890054818c1680/src/core/core.config.js#L40C1-L53C2

And then specificly this line: https://github.com/chartjs/Chart.js/blob/767d64e7a90dbfe94f9c5d159a890054818c1680/src/core/core.config.js#L47

It is looking at the first letter of your scale name to determine the axis type. This is not something that can be changed in V4 since it is breaking.

@LeeLenaleee I guess it is not well way to change type of graph from any to radial. But i got it maybe in the future they can change that. I guess many ppl can make mistake about it. There are many words which is starting from "R"or "r".
