graphic elements X coordinate

[jppeltier]

Hello Mathieu,

So, I have installed V3, and I confirm session handling is working flawlessly so far, well done! I however have something else troubling me regarding graphic elements. I don't expect it to be a bug from your scripts, but this issue might significantly impair the true potential of your tool.

Let's use the BINANCE:BTCUSDT daily chart, with Zig-Zag in-house indicator (code: "STD;Zig_Zag"). I found, in the study graphic element labels and lines corresponding to the Zig-Zag indicator as displayed. So, for such specific chart, we find indeed the following first elements:

• a label (in graphic.labels):

{
      id: 2,
      x: 0,
      y: 3400,
      yl: 'bl',
      t: '3400.00 (+3400.00) \n4.502K',
      st: 'n',
      ci: 1,
      tci: 2,
      sz: 'normal',
      ta: 'center',
      tt: ''
    }

; and

• a following line (in graphic.lines):

{
      id: 3,
      x1: 0,
      y1: 3400,
      x2: 1,
      y2: 4939.19,
      ex: 'n',
      st: 'sol',
      ci: 0,
      w: 2
}

If you check the TV interface, you will indeed find such, first label and line at the very beginning of quotations, in August-September 2017. However, the reported x, x1, x2 seem to be only an increasing series of coordinates (0, 1, 2, 3 ...) not matching either the dates, nor even the number of bars! By comparing in the TV interface, we should have:

• x: 0 is the 6th bar, corresponding to 22 August 2017 ; and
• x: 1 is the 17th bar, corresponding to 2 September 2017.

Hence my question: how can we match back x ordinal value with the number of bars or, better, the actual timestamp?

(tip: I checked graphic.indexes hoping to find my answer, but it remains desperately undefined ...)

Thanks!

Don't worry 😉
We are working on it in #17, I just have to translate all the abbreviations like 't', 'sz', 'ta', etc... to 'title', 'size', 'textAlign', etc... And do all the JSDoc. (You can help translate if you want)
