Perspective timeseries chart component last value on dataset display on chart and interpolation

There are two things on perspective timeseries chart.

  1. Last row on dataset is not visible on chart. My dataset has value for 23-03-2021 but it is not visible on chart.

  1. Though I set line chart to Curvestep and set axis, the chart on popup defaults to curvelinear and doesnt take set axes.

view in designer:

However popup screen on first picture defaults to curvelinear and auto axes.

Hi can anyone help on this? Thanks.
