How to pan to a specific date without changing the x-axis zoom level in finplot

[ericyan71]

I'm using finplot to display candlestick charts. I would like to programmatically navigate to a specific trading day (e.g., 2025-01-15) while keeping the current x-axis zoom level unchanged.

In other words, I want to shift the visible range so that the target date becomes visible, but the number of visible bars (or the time span shown) remains exactly the same as before.

Is there a built-in method or a recommended way to achieve this in finplot? Currently, I can set the x-axis limits manually, but that changes the zoom level. I just want to pan to a specific date.

Any help would be appreciated.

Currently there's

fplt.set_x_pos(df.index[a], df.index[b], ax=ax)

If you want a single-parameter implementation, I suggest you modify the current set_x_pos() implementation and send a pull request.
