Is it possible to render a candlestick series' bars at a constant pixel width?

WPF Pixel Coordinates FastCandlestickRenderableSeries width

I’m using a candlestick series in a slightly unconventional use case, essentially to show a range at a given data point, screenshot below.
enter image description here

This works fine if the number of the data points and window size stays the same, but if I resize the window, the bars shrink accordingly, which I want to avoid.
enter image description here

So basically what I need is some kind of rendering mode that takes in a pixel width for the bars.
I’ve attempted to update the DataPointWidth on the series using a combination of the screen width and the number of points, but it’s extremely messy since the change needed isn’t linear.

First column renders too wide until second column

Android FastColumnRenderableSeries append width

Hi,

I have a fast column renderable series where a column is added each hour. When the first column is added, it renders approximately half the graph (regardless of zoom), which is unintended. Once the data point for the second hour is added, the column collapses down to the space of the hour (as we would want). Why is the first column rendering too wide? Am I failing to set a parameter that is required?

Below is my series setup:

 val uoColumnSeries =
        generateColumnRenderableSeries(LABEL_ID_UO, uoColumnDataSeries, SolidBrushStyle(uoColumnColor))
    uoColumnSeries.dataPointWidth = .95
    uoRenderableSeries.add(uoColumnSeries)

Attached is how the data renders with 1 point (zoomed in and out), and data render once second point (of height 0) is added. The graph in question is the column graph at the top in yellow.

Thanks,
-Andy
