For an equidistant channel, it is possible to specify the mode of its continuation to the right and/or to the left (OBJPROP_RAY_RIGHT and OBJPROP_RAY_LEFT properties accordingly). The mode of filling the channel with color can also be set.
The following script creates and moves an equidistant channel on the chart. Special functions have been developed to create and change graphical object's properties. You can use these functions "as is" in your own applications.
