I want x-axis lineMark as this picture.
y-axis mark is working, but x-axis isn't.
y-axis mark code:
------------------------------------
Dim xy As XYChart
Dim line_mark As Mark
Set xy = c.addMainChart(300)
Set line_mark = xy.yAxis().addMark(day_open, &HFF00, day_open)
Call line_mark.setLineWidth(3): Call layer_mark.setDrawOnTop(False)
------------------------------------
How to addmark x-axis on finacechart?

Hi ddd,
Financial charts use trading sessions as the x-coordinate, not actually dates.
The date are "names" on the x-axis are for human reading only. They are arbitrary and unpredictable. (The trading days depend on the country, stock exchange location, other national laws, unexpected events, etc.... and is generally unpredictable.) All common technical indicators (such as moving averages, RSI, MACD, etc) are defined based on trading sessions, not dates. That's why the x-axis needs to be in trading sessions.
In the chart, the first visible position is x = 0, the second visible position is x = 1, etc.. For example, if you want to put a mark at the 20th visible trading day on the chart, the code is:
Call xy.xAxis().addMark(20, &HFF00, myTimeStamps(20 + extraPoints))
(Note: extraPoints are the extraPoints that you use in the FinanceChart.setData call.)
