Question

I am trying to modify a custom nvd3 chart on a page. I need to make certain parts of the generated graph visible, and others not. I am using the following to try and hide/show things:

$(document).ready(function() {
//Puts date label under Modal Day, may have to do custom switch
$("#dateTag").html(new Date().toDateString());

//Hides X-axis bars
$('.nv-y.nv-axis').addClass('hiddenClass');
$('#title').addClass('hiddenClass');

});

Where hiddenClass is :

.hiddenClass {
opacity: 0 !important;
visibility: hidden !important;
}

The generated HTML:

<g class="nv-y nv-axis">
<g class="nvd3 nv-wrap nv-axis">

This however does not seem to work - however if I add these properties in the inspector, the axis will disappear.

Answer 1

try

d3.selectAll('.nv-y.nv-axis').classed('hiddenClass',true)

When it comes to SVG-Elements sometimes D3.selection instead of jQuery solves the problem. Maybe take a look at D3 API for selection.classed
