Original Pull Request: https://github.com/radzenhq/radzen-blazor/pull/1989

State: closed
Merged: Yes

When a value series only has negative values, this happens:

Exception: System.ArgumentOutOfRangeException: Arg_ArgumentOutOfRangeException Arg_ParamName_Name, Step must be greater than zero
          at Radzen.Blazor.LinearScale.Ticks(Int32 distance)
          at Radzen.Blazor.Rendering.AxisMeasurer.YAxis(ScaleBase scale, AxisBase axis, RadzenAxisTitle title)
          at Radzen.Blazor.RadzenValueAxis.Measure(RadzenChart chart)
          at Radzen.Blazor.RadzenChart.UpdateScales()
          at Radzen.Blazor.RadzenChart.Refresh(Boolean force)
          at Radzen.Blazor.CartesianSeries`1.<SetParametersAsync>d__74[[...]].MoveNext()

My change should fix that.
