Hello,
I need to be able to draw a horizontal line (threshold) starting from
a specific value on the Y axis, across the width of the chart. The
value is set by the user, and when the chart first displays the line
is not to show. Once the user input the threshold number the line
displays. I've tried the examples that show the line between two data
points, but that doesn't work if there is on one column of data on the
chart, and I'm being pressed to display the line the whole width of
the chart, not just between columns. Help. Thanks in advance for all
your help.
