Grid/Trend lines

Add additional grid lines to the chart either on the X or Y Axis. You can add as many additional lines as you like.

Additional grid lines can have a label and are useful for such things as trend lines or intersects.

For each grid line

Axis

Y axis will add a horizontal line at the value defined. X axis will add a vertical line.

Value

This defines where the line will be added. The value must be within the dataset.

Label

Add an optional label to identify what the line represents. Eg average, min or max.

Label position

Define where the label appears on the line. Start, middle or end. On a X line start is the bottom, end is the top.

Adding and removing lines

Clicking 'Add line' will add a new empty line. Clicking 'Remove line' will remove the last line in the list.
