'How to set custom scale to polar area chart?
The Problem:
I am using polar area chart. For slices in this chart, each value after the largest value should appear one level smaller. The level is as follows: for example, if the value after a 38 slice is 6, it should look like 37. Or I should be able to set it to the level I want. My question is all about sizing the slices on the polar area.
What I get:
What I want:
Sorry for my bad drawing. You can think what i want is like:
scaling very small slices close to large slice.
Methods I tried:
- I tried changing the scale and ticks parameters from the link chartjs axes settings but without success.
- I put the index data after sorting the array as data into the dataset. It worked as I wanted, but this time the values appeared as index values.
- Charts.js polar area scales I tried this also but not worked.
A solution can be reached from the two methods I tried, but I could not.
Code example here:
function SetWorkflowChart(labels, datas, labelColors) {
//label colors
// workflow stats chart
const workflowdata = {
labels: labels,
datasets: [{
normalized: true,
data: datas, // example data: [38, 5,3]
backgroundColor: labelColors,
borderColor: "rgba(0, 0, 0, 0.0)"
}]
};
const workflowconfig = {
type: 'polarArea',
data: workflowdata,
options: {
scales: {
r: {
grid: {
display: false
},
ticks: {
display: false //try2 i tried to set ticks for scale
},
suggestedMin: 5, //try1
suggestedMax: 20,//try1
}
},
plugins: {
legend: {
display: false,
position: "right"
},
},
responsive: false
}
};
workflowChart = new Chart(
document.getElementById('WorkFlowStatsChart'),
workflowconfig
);
}
I'll be pleased if you pay attention.
