BarChart is a chart that represents grouped data with
rectangular bars. It can be monochrome - defaut behavior.
One can assign individual color to each bar and even use
custom drawn bars to display multicolored bars depending
on bar value.
All bars have the same width: either constant BarSize - in
case of AutoSize is false, or automatically calculated but
cannot be less than BarSize. Bars that do not fit the chart
area are not displayed.
BarChart displays vertical axis with values on the chart left
if ValueWidth greater than 0, horizontal axis with bar titles
if ShowTitles is true (to enable displaying marks on horizontal
axis, set ShowMarks to true), and chart legend on the right if
LegendWidth is greater than 3.
If LegendWidth is greater than half of the chart it is not
displayed. The same is applied to ValueWidth
SparkChart is a chart that represents a live data that
is continuously added to the chart. Or it can be static
element that displays predefined set of data - in this
case it looks like BarChart. At a moment SparkChart
keeps only th enumber of last data that is enough to
fill the control area. So, if you enlarge the control,
it will show partially filled area until it gets new data.
SparkChart displays vertical axis with values on the chart left
if ValueWidth greater than 0, horizontal axis with bar titles.
Maximum peaks(maximum of the the data that control keeps)
can be hilited with different color.
By default the data is autoscaled to make the highest bar
fit the full height of the control. But it maybe useful
to disable autoscale and set the Top value to have more
handy diagram. E.g, for CPU load in % you can set
AutoScale to false and Top value to 100.
Note: negative and zero values are displayed as empty bar
