Sparkline graph opacity with MVC

[Andrew]

Anyway to change the opacity for the background the sparkline graphs in MVC. I would even accept changing the background color.

Hello Andrew,

You could change the background via Background option of the plotArea / chartArea. I.e.: 

@(Html.Kendo().Sparkline()
  //....
  .ChartArea(c=>c.Background("red"))
  .PlotArea(p=>p.Background("green"))
)

As for the background opacity, it appears there is a bug in the current version of Kendo UI Chart for ASP.NET MVC and it is not possible to set opacity to the chartArea / plotArea. I forwarded the issue to our developers - we will do our best to provide a fix as soon as possible. Please excuse us for the inconvenience caused.

Did this ever get fixed?  I have the same need.  I want to set the background and chart are to be transparent, while keeping the databar itself NOT transparent.  Today it seems that setting the opacity changes both to be transparent... can you tell me the fix?

Hi Travis,

You could set transparent background to the ChartArea while keeping the series not transparent:

@(Html.Kendo().Sparkline()
    //....
    .ChartArea(ch => ch.Background("transparent"))
)
