ichart.js Implementation code to draw a dashed line, average dotted line effect

var data=new Array (); 
          Data[0] = {labels: ["Unit One", "Unit Two", "Unit three", "Unit Four", "Unit V"], datasets: [{name: ' Excellent rate ', Color: ' #1dbcfe ', line_width:4, Value: [80,75,92,62,0]}]} Da 
          Ta[1] = {labels: ["Unit One", "Unit Two", "Unit three", "Unit Four", "Unit V"], datasets: [{name: ' Excellent rate ', Color: ' #1dbcfe ', line_width:4, Value: [50,11,62,77,90]}]} Dat 
          A[2] = {labels: ["Unit One", "Unit Two", "Unit three", "Unit Four", "Unit V"], datasets: [{name: ' Excellent rate ', 
     
    Color: ' #1dbcfe ', line_width:4, Value: [80,51,32,44,80]}]} 
    var _bodywidth=$ (' body '). Width ()-16; 
      $ ('. Item '). Each (the function (i) {var _id=$ (this). Find ('. Canvas-wrap '). attr (' id '); var chart = new Ichart.linebasic2d ({render: _id, Data:data[i].datasets, ALIGN: ' Center ', border:0, Width: _bodywidth*2, Height: _bodywidth*1.2, Background_colo R: ' #fafafa ', animation:true,//turn on transition animation animation_duration:600,//600ms complete animation sub_option 
          : {smooth:true, Hollow:false, Hollow_inside:false, Point_size:16, 
            Listeners: {parsetext:function (R, t) {return t+ '% '; }, Label:{fontsize:24,color: ' #333 '}, coordinate:{width:_bodywidth 
          *1.6, valid_width:_bodywidth*1.4, height:_bodywidth*1.6*.5, striped_factor:0.18, axis:{color: ' #aaa ', width:[0,0,8,0]}, scale:[{Positi On: ' Left ', start_scale:0, end_scale:100, scale_space:20, Scale_si

       /** * Custom component, draw the average line. 
             /Chart.plugin (new Ichart.custom ({drawfn:function () {/** *) calculates the average height (coordinate y value) 
            * * var _total=0; 
            $.each (Data[i].datasets[0].value,function (i,val) {_total+=val; 
            }); 
              The var avg = _total/data[i].datasets[0].value.length,//calculates the average score in this can be COO = chart.getcoordinate (), x = Coo.get (' Originx '), W = coo.width, S = Coo.getscale (' left '), H = coo.he 
            ight, H = (avg-s.start) * h/s.distance, y = chart.y + h-h; For (xi=x;xi<= (x+w); xi=xi+32) {chart.target.line (xi,y,xi+16,y,2, ' #fe941c '); } chart.target.textAlign (' Start '). Textbaseline (' Middle '). Textfont (' 20px Verda 
          Na '). Filltext (' average defeating rate ' +avg+ '% ', x+w-100,y-20,false, ' #fe941c '); 
      } 
      })); 
    Chart.draw (); });

The above code is a JS example of drawing multiple line charts, and a way to draw an average dotted line within each line chart.

Ichart.js is a very good icon to draw JS, the disadvantage is that the mobile end needs to set twice times the size, and then manually reduce the CSS and JS to the normal range to keep it on the screen to maintain high-definition.

The official website has an example of an average line, but there are no dotted lines, and in general, in order not to confuse, the average line is drawn with a dash. Here I'm just looping through the N-end line, which is a flexible method. If there is a better way please leave a message oh thank you.

The above ichart.js draw dotted line, the average dotted line effect of the implementation code is small series to share all the content, hope to give you a reference, but also hope that we support the cloud-dwelling community.
