Re: Adding a movable line on a chart

Sorry a quick followup question.

How do I get the values of the candle under the line, as the line moves I want to see the values reflected in a table. I do this today by clicking on a point, but users want something more dynamic

Thanks

Re: Adding a movable line on a chart

Re: Adding a marker on a Candle chart

Re the 1st point, thanks, I will track the bug, Re the 2nd point - sorry that's not correct, If I comment that line out the dates are not displayed along the x-axis although interestingly if I do comment it out then '3' appears on the X-axis under the relevant candle. Just to be clear on what I want...

Re: Adding a marker on a Candle chart

Sorry but that didn't work, it still displays a date, I will get you a simple project over the weekend as its right in the middle of a huge piece of code so I will need to work on that.
