Try this:

<?php

$thumb = kdmfi_get_featured_image_src( ‘your-featured-image-id’, ‘full’, $post->ID ); ?>

then

<div class=”header-image parallax-background-image” data-stellar-ratio=”0.85″ style=”background-image: url(‘<?php echo $thumb;?>’)”>
<div class=”wrapper”>

Try with this url structure

https://example.com?exclude=dogs,cat,fish

this code

$exclude_tags = explode(",", $_REQUEST['exclude']);;
$exclude_tags_ids = array();

foreach( $exclude_tags as $i){
       $exclude_tags_ids[] = get_term_by('slug',$i, 'post_tag');

}

$args=array(
  'tag__not_in' => $exclude_tags_ids,
  'post_type' => 'post',
  'post_status' => 'publish',
  'numberposts'=>20,
  'caller_get_posts'=> 1
);
$my_query = null;
$my_query = new WP_Query($args);
 ....

Like Ross says, there are a lot of chart plugin in wp-plugin repository.

Try to use WP AJAX API and with jquery

in function.php of your theme add

add_action( 'admin_footer', 'my_action_javascript' ); // this need to print <script> in footer, add  my_action_javascript function to wp_footer

function my_action_javascript() { ?>
	<script type="text/javascript" >
	jQuery(document).ready(function($) {
		var data = {
			'action': 'my_action', // name of php function
			'userid': 1234 // var to send
		};

		$.post(ajaxurl, data, function(response) {
if(data){
      $('#replaceMe').html(data);
}
		});
	});
	</script> <?php
}

add_action( 'wp_ajax_my_action', 'my_action_callback' ); // for logged user
add_action( 'wp_ajax_nopriv_my_action', 'my_action_callback' ); //for every user
function my_action_callback() {

	$userid = intval( $_POST['userid'] ); // receive var form ajax call
        // put here your function
	$user = get_post($userid);
        if($user){
             $html = '<h3>'.$user->post_title.'</h3>';
             $html .= '<p>'.$user->post_content.'</p>';
}
        echo $html;

	wp_die(); // this is required to terminate immediately and return a proper response
}

You can try full documentation here

https://codex.www.ads-software.com/AJAX_in_Plugins

you mean wp_list_categories?
https://codex.www.ads-software.com/Template_Tags/wp_list_categories

try to change this in header.php
<meta name=”viewport” content=”width=device-width,initial-scale=1″>

with something like
<meta name=”viewport” content=”width=1200,initial-scale=1″>

you must edit style.css, and change height property of #footer
(https://www.canadianmacedonianplace.com/wp-content/themes/twentyten-childcmp/style.css)

#footer{
height: 340px;

try this for js

$('#content').infinitescroll({
     	navSelector  : ".navigation",
    	nextSelector : ".navigation .next a",
    	itemSelector : "#content .post" ,
});

and this for pagination

<nav id="navigation">
	<div class="past"><?php previous_posts_link('&laquo; Previous Entries') ?></div>
	<div class="next"><?php next_posts_link('Next Entries &raquo;','') ?></div>
</nav>

this work for me ?? my custom field is with price but without €$r, symbols…
you can try to order with javascript/jquery

(function( $ ) {
jQuery.fn.orderBy = function(keySelector,inverse){
    return this.sort(function(a,b){
        a = keySelector.apply(a);
        b = keySelector.apply(b);
		return (
			isNaN(a) || isNaN(b) ?
				a > b : +a > +b
		) ?
		inverse ? -1 : 1 :
		inverse ? 1 : -1;
    });
};})( jQuery );

$(".preco").orderBy(function(){
		return +$(this).text();
	},true);

in single page work only next post/previus post
code is

<?php previous_post('&laquo; &laquo; %', '', 'yes'); ?>
| <?php next_post('% &raquo; &raquo; ', '', 'yes'); ?>

put it in single.php

You can try to create new post type for your blog, (for example ‘portfolio’). Basically a new label appear in your backend, you can edit/manage it like a page or post, you can link it to category or custom taxonomy, the same in template hierarchy.
check here:
https://kovshenin.com/2010/custom-post-types-in-wordpress-3-0/
https://wp.tutsplus.com/tutorials/theme-development/innovative-uses-of-wordpress-post-types-and-taxonomies/

here a post type generator
https://themergency.com/generators/wordpress-custom-post-types/?1

sorry ?? try with this

$argsvs = array(
    'post_type' => 'imovel-para-venda',
    'meta_key' => 'wpcf-imovel-preco',
    'posts_per_page' => 0,
    'orderby' => 'meta_value',
    'order' => 'ASC'
);

https://codex.www.ads-software.com/Class_Reference/WP_Query#Order_.26_Orderby_Parameters

i dont understand what you want to do, but right way to call metaquery for custom order is

$argsvs = array(
		'post_type' => 'imovel-para-venda',
		'posts_per_page' => -1,
	 	'meta_query'        => array(
            'key' => 'wpcf-imovel-preco',
            'value' => 'meta_value_num',
            'compare' => '>'
        )
    );

i found a solution by installing this plugin
https://www.ads-software.com/extend/plugins/show-future-posts-on-single-post/

and for show in single post i use this plugin
