How to get data when using datasets and transformations?

[CalvinMau]

Version

5.0.2

Steps to reproduce

i cannot find a API to get the result after dataset has transformed.

What is expected?

A API or another solution to get the transformed data.

What is actually happening?

Before. we can use the aXis and series data length to control the datazoom. Now. we use the dataset and transform to render the chart. we cannot get the data of current view. so we cannot to control the data-zoom through data. Could you please give some suggestion to us to get the current view data (transformed).

You cannot get the transformed data. What do you need the data for?

in our case, we add a custom series (a polygon) based on the data from each existing line series. think of it like the confidence band, but with the possibility to have values above and below zero.

I am trying to rework this now to using datasets and it would be great to have a way to access the data for each series/dataset after the transformation (which is right now a simple filter based on the series name)

@CalvinMau Could we know how do you use the aXis and series data length to control the datazoom ?

In my case, I need to get the selected data within brush area, the brushSelected event params only returns seriesIndex and dataIndex, and the corresponding series are using transformed dataset, so I am also wondering how to get the actual data values within brush area?

i'm also having the same issue, does anyone have any workarounds?

[ZhengRui]

in my case, i had to implement my own transform method and generate the transformed datasets explicitly and let series points to these transformed datasets
