研究方向

首先重現連結的 Plotly 範例和 CodePens 中的 slider 與動畫案例,包括不同的 trace 數量,以及單點或空的 trace。追蹤 slider 更新和動畫影格如何套用資料物件;當所有 trace(包括新增的、單點的和空的 trace)都能正確反映每個選取的步驟時,即表示完成。

描述

bug P3

I'm trying to create a plot with a slider that will change all the traces. I have started with the example on the plotly page here and I have created a code pen to show a few problems I have noticed:

  • If I don't have originally the same number of traces (that is, if line 10 is commented), then new traces are not added on the other steps/frames - even though I'm adding them to the "data" object, which I believe should be completely updated.
  • Even when I have now the same number of traces, if one of them has a single point (lines 90/91) or is empty, then the trace is not updated completely: in the code pen example, moving to green will add the second line trace, then going back to red will move the point but the green line is stuck there. For graphs with at least 2 points (for example, changing the lines 90/91 to at least 2 points (e.g. x:[2,3], y:[1,1],)) the issue is not present.

I believe the data object is not being updated completely, which is something I'd have expected it to do.

PS: I have noticed similar problems with sliders without the "animate", although the objects seem - strangely - to be different (for example, in this codepen I have to pass arguments as x: [[1, 2, 3]], y: [[2, 1, 3]], in args to update more than one trace, but the issue of having to have at least one trace and traces not updating are also there.
