This plugin adds a widget to display download statistics based on the <a href="https://wordpress.org/extend/plugins/wp-downloadcounter/" rel="ugc">Download Counter</a> 
plugin on your site. The sidebar widget will show a highly configurable chart based on the 
<a href="http://code.google.com/apis/chart/" rel="nofollow ugc">Google Chart API</a>. Furthermore it offers a dashboard widget that summarizes your 
downloads, to get information quick at a glance.
The plugin supports following chart types:
<ul>
<li>Bar (horizontal)</li>
<li>Pie </li>
<li>Pie 3D</li>
</ul>
You can include a chart of your downloads on a page or in a post using the downloadcounterchart-shortcode. 
Of course a download chart is includable in your theme. See <a href="https://wordpress.org/extend/plugins/wp-downloadcounter-chart/other_notes/" rel="ugc">extended documentation</a> 
for detailed explanations for that.
<h3>Usage</h3>
There are several ways to include a chart of your downloads on your site.
<h4>Page / Post (Shortcode)</h4>
<pre>[downloadcounterchart chart_type="pie" chart_width="490" chart_height="190" label_color="000000" label_size="11" sqlcondition="" bar_color="0066CC90" bar_height="-1" bg_color="FFFFFF00"]</pre>
Parameters:
<ul>
<li>chart_type – Type of the chart. Valid values: <code>bar_horizontal</code>, <code>pie</code> or <code>pie3d</code>.</li>
<li>chart_width – Width of the chart image in px. May be about the 2.5 times size of the height for a pie chart.</li>
<li>chart_height – Width of the chart image in px.</li>
<li>label_color – Hex color value for labels, optional with additional opacity value (e.g. 50% black = 00000050).</li>
<li>label_size – Font size of the labels.</li>
<li>sqlcondition – Optional SQL where statement, leave blank for all downloads.</li>
<li>bar_height – Bar chart only. You can explicitly set the bar height, but it may result in a chart that does not include 
all data, if the chart height is not big enough. Recommend to set <code>-1</code> for auto-sizing.</li>
<li>bg_color – Background color. Hex color value, optional with additional opacity value (e.g. transparent = FFFFFF00)</li>
</ul>

<pre>downloadcounterchart_img($chart_type, $chart_width, $chart_height, $label_color = '333333', $label_size = '11', $sqlcondition = '', $bar_color='', $bar_height='', $bg_color='')</pre>
Parameters:
see section above
Example:
<pre>if (function_exists('downloadcounterchart_img') && class_exists('DownloadCounterChartApi')){
 downloadcounterchart_img(DLC_CHART_PIE, 490, 190, '000000', '11', '', '0066CC', '-1', 'FFFFFF00');
}</pre>

This plugin loads JavaScript libraries from external amCharts CDN which is a free service provided by amCharts.
amCharts provides their libraries completely free without any caps to functionality on a sole condition, that small contribution is automatically displayed on all chart produced by amCharts library. The contribution comes from amCharts libraries/service and is not added by this plugin.

<h4>What is it?</h4>
Ever tried getting JavaScript content into your WordPress posts or pages? Yeah, that’s impossible. WP strips down all 
the JavaScript.
This makes adding JavaScript Charts and Maps a hassle.
Developed and maintained by amCharts staff, this plugin solves the problem by allowing you to create chart code snippets, that then subsequently can be inserted into the 
posts or pages as a shortcode. (helpful button in TinyMCE is also there)
You can also use a built-in PHP function to invoke the chart anywhere in your template:
<pre><code><?php amcharts_insert( $chart_id ); ?>
</code></pre>
The plugin has also many helpful functions:
<ul>
<li>Easy switching between CDN-hosted or local chart/map libraries storage</li>
<li>Setting defaults per chart type</li>
<li>Automatically locating installed libraries and available resources</li>
</ul>
