    Every time the chart is drawn the background is set to gray. No matter if the theme is specified or not or if the chart area background is set to "", "transparent" or any color, or not at all.

    You can see a blank chart with the correct background color prior to the read occurring and the chart being redrawn with the appropriate data. Each path element in the SVG has a stroke color set to "#dfdfdf"

    Here is the code:

    @(Html.Kendo( ).Chart<ViewModels.HistoryChartModel>( )
    .Name( "chart" )
    .DataSource( dataSource => dataSource
        .Read( read => read.Action( "Series", "Home" ) )
        .Group( group => group.Add( model => model.BasinName ) )
        .Sort( sort => sort.Add( model => model.ReadingDateTime ).Descending( ))
    .Series( series => {series.Line( model => model.LevelReading ).Name( "#= group.value # " ).Markers(false);} )
    .Legend( legend => legend.Position( ChartLegendPosition.Bottom ))
    .ValueAxis( a => a.Numeric( ).Min( 3 ).Max(10).MinorTicks(mt=>mt.Visible(false)).MajorUnit(.5) )

    After some more investigation it is actually the plot area that is affected, not the chartarea.

    Hi Bill,

    I posted a reply in your other thread on the same subject (1014683), however I am pasting my answer here too so the other users who are folling this thread can read it: 

    Generally speaking, the chartArea background comes from the selected theme (if not explicitly set). If I am right, you are using the Silver theme? In order to avoid the gray background I would suggest the following options: 
    - Set a different theme to the chart: 

    - Set chartArea / plotArea backgrounds: 

    If these suggestions does not help please provide an isolated runnable example which I could test locally - this way I would be able to check what exactly is going wrong and provide concrete recommendations.
