Bar pod: discrete and non-discrete types
Changes:
- New bar pod structure and options
- Bar Pod should be set up as "discrete" or "non-discrete" in options
- discrete type for standard bar chart with similar X values for each metric
- non-discrete type for metrics independent of each other
- Stacked bars -> multiple Y values in datapoints in one serie instead of multiple series
- Group bars -> multiple series
