jrCore_list
You can use the chart_field in jrCore_list calls like this:
{jrCore_list module="jrAudio" chart_field="audio_file_stream_count" chart_days="7" tpl_dir="jrFlashback" template="music_chart_row.tpl" pagebreak="5" page=$_post.p}
That will look for the
'music_chart_row.tpl' template in the jrFlashback skin:
/skins/jrFlashback/music_chart_row.tpl
Available in that template will be variables related to the computed movement of the item over the specified period.
Some useful ones will be:
{$item.chart_direction}
{$item.chart_change}
{$item.chart_new_entry}
{$item.chart_position}
