Scale Y-Axis in TS Plots Dynamically

[rywhale]

The Y-Axis on the time series plots should scale dynamically to the min/max of the values when you change the time period.

Currently we go from

to

The scale needs to change in the second plot or the data isn't readable.

I'm not too sure I understand. Would the second plot Y-axis be between 2.46 and 2.5?

[rywhale]

Yeah, the Y-axis in the second plot should scale to the min/max of the data in the second plot. In other words, every time you change the time range with one of the selectors (all, 6m, 1m, 1w), the Y-axis should automatically scale to the min/max values in the time range.

So if the min/max in the second plot are 2.46/2.5 you would scale to those values. The issue is that the second plot looks flat when in reality there is still some fluctuation going on there

I'll look into it. The Plotly library is nice but customization can be a pain.

@Julien-Cousineau we see the scaling of y-axis is a pretty high priority vs other issues so would be great if this could get some focus.

From plotly:https://github.com/plotly/plotly.js/issues/1876 The axis auto-range is currently not available.

Possible temporary solution: Hard code y-axis based on selected data.

1. Add clicking event = >(div.on('plotly_relayout',function(relayoutData){})) :heavy_check_mark:
2. filter data based on dates = >relayoutData={xaxis.range[0]:start,xaxis.range[1]:end} :heavy_check_mark:
3. find min max :heavy_check_mark:
4. adjust graph :heavy_check_mark:

My temporary code seems to be working. However the range slider at the bottom use the same y-axis as the chart as shown below. Please let me know if that is an issue.

@Julien-Cousineau Looks good to me

Could you provide some (coding-) details on how you solved it? Would it be possible to integrate it via event handlers in R?
