When the chart option "Show OHLC" is set to vertical, the IChart.comment is overlaid by the OHLC-information.
As a workaround the comment could start with a series of linefeeds, but that would leave the comment somewhat low
in case OHLC is set to horizontal.
It would be better if the ICHart.comment() function itself would dynamically place the text based on the "Show OHLC"-settings OR
just always add a linefeed and the comment to the OHLC-text string (so set them as one string).
