I'm working on an SVG gauge meter here I want to divide the semi-circle into parts when the range slider move on active stroke fill with gradient color. And want to add one more black color running track when the meter needle moves. I had tried using stroke-dasharray but after adding this all colors are coming at a time meter is not working properly.
- I want to divide the semi-circle into parts when the range slider move on active stroke fill with gradient color
- And I want to add one more black color running track when the meter needle moves.
My code here
/* set radius for all circles */
var r = 400;
var circles = document.querySelectorAll('.circle');
var total_circles = circles.length;
for (var i = 0; i < total_circles; i++) {
circles[i].setAttribute('r', r);
}
/* set meter's wrapper dimension */
var meter_dimension = (r * 2) + 100;
var wrapper = document.querySelector('#wrapper');
wrapper.style.width = meter_dimension + 'px';
wrapper.style.height = meter_dimension + 'px';
/* add strokes to circles */
var cf = 2 * Math.PI * r;
var semi_cf = cf / 2;
var semi_cf_1by3 = semi_cf / 3;
var semi_cf_2by3 = semi_cf_1by3 * 2;
document.querySelector('#outline_curves').setAttribute('stroke-dasharray', semi_cf + ',' + cf);
document.querySelector('#high').setAttribute('stroke-dasharray', semi_cf + ',' + cf);
document.querySelector('#avg').setAttribute('stroke-dasharray', semi_cf_2by3 + ',' + cf);
document.querySelector('#low').setAttribute('stroke-dasharray', semi_cf_1by3 + ',' + cf);
document.querySelector('#outline_ends').setAttribute('stroke-dasharray', 2 + ',' + (semi_cf - 2));
document.querySelector('#mask').setAttribute('stroke-dasharray', semi_cf + ',' + cf);
/*bind range slider event*/
var slider = document.querySelector('#slider');
var lbl = document.querySelector("#lbl");
var mask = document.querySelector('#mask');
var meter_needle = document.querySelector('#meter_needle');
function range_change_event() {
var percent = slider.value
var meter_value = semi_cf - ((percent * semi_cf) / 100);
mask.setAttribute('stroke-dasharray', meter_value + ',' + cf);
meter_needle.style.transform = 'rotate(' + (450 - ((percent * 180) / 100)) + 'deg)';
lbl.textContent = percent + '%';
}
