To display a solid line on the chart without using the "Display missing values as zeros" function
Sometimes there is a need to display a solid line on the chart without using the "Display missing values as zeros" function. Here is a widget script that will read the average value between two neighboring points and draw a line.
widget.on('processresult', function(widget, result) {
const series = result.result.series;
for (let j = 0; j < series.length; j++) {
const data = series[j].data;
for (let i = 0; i < data.length; i++) {
if (data[i].y === null) {
let leftIndex = i - 1;
let rightIndex = i + 1;
while (leftIndex >= 0 && data[leftIndex].y === null) {
leftIndex--;
}
while (rightIndex < data.length && data[rightIndex].y === null) {
rightIndex++;
}
const leftValue = leftIndex >= 0 ? data[leftIndex].y : null;
const rightValue = rightIndex < data.length ? data[rightIndex].y : null;
if (leftValue === null && rightValue === null) {
data[i].y = 0; // You can change this default value
} else {
const average = ((leftValue || 0) + (rightValue || 0)) / 2;
data[i].y = average;
}
}
}
}
});
