The micro chart supports very small chart sizes and can be displayed as line, area, and column chart. A micro chart can display one dimension and two measures.
Micro charts offer several preconfigured visualizations. The chart can be shown in a very simple fashion (Plain). It is possible to show and hide the axes.
For each measure displayed, the first and last highlight information and the side labels are displayed in the diagram by default. The highlight information puts a focus on certain data points, like the first and the last values (First/last), the best and worst values (Top/flop) or perhaps just the last one (Last value). It is possible to determine the "Label placement". These can be shown lateral of the chart (Lateral), within the chart (In chart) and on top of the chart, in the area of the sub title.
