Axis

By default 5 axis on each side of the chart are available. If you need mode, just take a look into frontend/View/Index/dialog.chart.tpl :-)

The axis unit label is detected from the 1^st channel assign to this axis, so take care to attach channels of the same unit to the same axis.

Series display type

Dash style

Use these styles for visual alignment of channels.

Line width

Use these different 3 line width for highlighting channels.

Mark reading values

You can mark several values with a value label. "All" is only useful for bar charts

Presentation

For meter channels you can show the values according to the consolidation period, see Bar chart example for details.

Color

Some collors are pre-defined, you can choose from the whole color range.

Color for values below threshold

To make e.g. negative values more visible, you can show them in a different color.

Please see also the following examples.

Time range

Sometimes, when you show channels only filled during daylight times and 24hr channels together, you are interested only in a part of the whole data. In this case you can specify for the 24hr channel a time range to display, see the limited time range example.
