javascript - Remove blank space below and above google graph? -


i have used google graph on particular page after few contents. number of rows(data) in google graph increases, space between content , graph increases. have tried modify height, no result.

here code - 

function drawchart() {     var data = new google.visualization.datatable();         data.addcolumn('string', 'projects');         data.addcolumn('number', 'hours');         var monthdata = jquery(".slick-active").html();         var monthtemp = monthdata.tostring().split(" ");         var month = getmonthfromstring(monthtemp[0]);         var year = monthtemp[1];         var tag = $("#tagval").val();         var jsondata = jquery.ajax({         url: "/report/additionalprojecthours",                 type: "post",                 datatype: "json",                 async: false,                 data: {month: month, year: year, tag:tag},                 beforesend: function (request) {                 return request.setrequestheader('x-csrf-token', $("meta[name='token']").attr('content'));                 },                 error: function () {                 //alert("errorrrrrr");                 }         }).responsetext;         var options;         var chartheight;         if ((jsondata.length) > 134) {              if (jsondata.length < 200){                  chartheight = 250;             }else{                 chartheight =jsondata.length ;             }               var options = {                 height: chartheight / 1.3 - 100,                 color: "#0f00ff",                 fontname: "times-roman",                 fontsize: 15,                 bold: true,                 series: {                     0: {                         visibleinlegend: false                     }                 },                 bar: {                     groupwidth: '20%'                 }             };             var data = new google.visualization.datatable(jsondata);             // instantiate , draw our chart, passing in options.             var chart = new google.visualization.barchart(document.getelementbyid('chart'));             chart.draw(data, options);         }else {           $("#chart").html('<p style="margin-right: 70px;font-family: times-roman; text-align: center; padding: 20px;">no data available</p>');         }         $('defs').nextall("g").eq(1).hide();    }

screen shot of graph

i expect problem here:

chartheight =jsondata.length ;

jsondata string, setting height of chart equal number of characters in string. try setting height based on number of rows of data in datatable instead:

var data = new google.visualization.datatable(jsondata); options.height = data.getnumberofrows() * <height per row> + <offset chart header , footer>;
