program of drawing Vertical line on candlestick chart

[xiupingge]

Hello, could some one tell me how to program of drawing vertical line on candlestick chart in indicator?
For example, I want to draw one vertical line on each 0 o'clock of hourly candlestick chart.
The line can be from the botton to the top of the chart panel.
better to cover two area, one is the main candlestick chart, the other is the subordinated chart, from the bottom of the subordinated chart to the top of the main chart.

Thanks a lot in advance.

You can use core.host:execute("drawLine".....) function to draw a line on the chart. If you need a vertical line you simply should put same dates into fromDate and toDate parameters. You can find a little sample in the attachment. To find more information about drawLine function you can read this http://www.fxcodebase.com/documents/Ind ... wLine.html
