Error in Plotly.Blazor.PlotlyChart.OnAfterRenderAsync(Boolean firstRender) when trying to display plot

[maciej-napora]

I am trying to use Plotly to plot a graph in time domain (DateTime as X axis data elements). I get an error:

Error: System.AggregateException: One or more errors occurred. (One of the identified items was in an invalid format.)

---> System.FormatException: One of the identified items was in an invalid format.

Any suggestions why this might be occuring are appriciated,

It turned out that on of the points had Double.MaxValue as value and the chart, using Decimal, throws an exception when encounters an overflow.
