uff, that was a long time ago ;-) i'll just share my unfinished code so you
can see for yourself:
```
// function blockZones(txm, azi, len) {
function blockZones(data) {
console.log("loading block zones");
// const blockZonesDiv = document.createElement("div");
// blockZonesDiv.style = "width: 90%; height: 500px"
// document.getElementById("content").appendChild(blockZonesDiv);
// var bzChart = echarts.init(blockZonesDiv, null, {
var bzChart = echarts.init(document.getElementById("blockZones"), null, {
renderer: "canvas",
useDirtyRect: false
});
const block = new Array(360).fill(0);
// for (i = 0; i < len; i++) {
// if (txm[i] == 1) {
// block[azi[i]]++;
// }
// }
// // because logarithmic scale is not working: see radiusAxis
// for (i = 0; i <= 360; i++) {
// if (block[i] >= 1) {
// block[i] = Math.log10(block[i]);
// }
// }
data.map((d) => {
if (d.txm == 1) {
block[d.azi]++;
}
});
block.map((b, i) => {
if (b >= 1) {
block[i] = Math.log10(b);
}
});
var option = {
angleAxis: {
type: "category",
// not working with category:
// data: ["0", "22.5", "45", "67.5", "90", "112.5", "135", "157.5",
"180", "202.5", "225", "247.5", "270", "292.5", "315", "337.5"],
// interval: 22.5,
// splitnumber: 16,
min: 0,
max: 359,
},
radiusAxis: {
// logarithmic scale not working:
https://github.com/apache/echarts/issues/16919
// type: "log",
// logBase: 10,
min: 0,
max: "dataMax",
axisLine: { show: false, },
axisTick: { show: false, },
axisLabel: { show: false, },
},
polar: {
},
tooltip: {
formatter: (params) => {
return params.name + "°: " + Math.round(Math.pow(10, params.data)) +
" TX Off events";
}
},
series: {
type: "bar",
data: block,
coordinateSystem: "polar",
itemStyle: {
color: "#bd565d",
},
},
};
bzChart.setOption(option, true);
}
```
