This Chart is a 100% Stacked Column Chart, where each series represents a channel and each point's
looks like a stacked column itself, demonstrating the contents of programs on this channel. Categories which
are distributed along the X-Axis are years, so the comparison between the percentage of the revenue from
different shows ads takes place by year. Labels and grid are disabled, but the legend
is switched on (you can find it to the right from the chart) so it is possible to enable/disable any series
any time you need. The chart title is positioned in the center of the chart.
