JavaScript Threshold Line Chart

xy line dashed constantline

Example showcasing use of DashedLine style in a threshold indicator.
In this case, the Y axis (temperature celsius) has a threshold value of 120 celsius. Imagine, that it is a value that should not be exceeded to stay in safe limits.

The application uses a ConstantLine on the Y Axis to display this threshold value to the user. The line is drawn across the Axis, which makes it easy to spot when a line trend goes over the threshold.

DashedLine style is used on this ConstantLine to clearly separate its style from the main data (line trends).
