Appearance
Unlike other Telerik UI for ASP.NET Core components which use only CSS for styling, you can mainly control the appearance of the Chart elements by using JavaScript style options.
For more information on the structure of the Chart, refer to the articles on the Chart building elements.
Predefined Themes
The Charts come with a set of predefined themes. To select a theme, use the Theme option. The theme name is case-insensitive.
@(Html.Kendo().Chart()
.Name("chart")
.Theme("blueOpal")
.Title("Site Visitors Stats /thousands/")
.Legend(legend => legend
.Position(ChartLegendPosition.Bottom)
)
.SeriesDefaults(seriesDefaults => seriesDefaults
.Column().Stack(true)
)
.Series(series =>
{
series.Column(new double[] { 56000, 63000, 74000, 91000, 117000, 138000 }).Name("Total Visits");
series.Column(new double[] { 52000, 34000, 23000, 48000, 67000, 83000 }).Name("Unique visitors");
})
.CategoryAxis(axis => axis
.Categories("Jan", "Feb", "Mar", "Apr", "May", "Jun")
.MajorGridLines(lines => lines.Visible(false))
)
.ValueAxis(axis => axis
.Numeric()
.Line(line => line.Visible(false))
)
.Tooltip(tooltip => tooltip
.Visible(true)
.Format("{0}")
)
)
@addTagHelper *, Kendo.Mvc
@{
var total_visits = new double[] { 56000, 63000, 74000, 91000, 117000, 138000 };
var unique_visitors = new double[] { 52000, 34000, 23000, 48000, 67000, 83000 };
var categories = new string[] { "Jan", "Feb", "Mar", "Apr", "May", "Jun" };
}

<series>

Sass Themes
As of the R2 2017 SP1 release, the Chart provides styling options through Sass-based themes. When the theme is set to sass, the Chart reads colors and fonts from the theme variables.
@(Html.Kendo().Chart()
.Name("chart")
.Theme("sass")
.Title("Site Visitors Stats /thousands/")
.Legend(legend => legend
.Position(ChartLegendPosition.Bottom)
)
.SeriesDefaults(seriesDefaults => seriesDefaults
.Column().Stack(true)
)
.Series(series =>
{
series.Column(new double[] { 56000, 63000, 74000, 91000, 117000, 138000 }).Name("Total Visits");
series.Column(new double[] { 52000, 34000, 23000, 48000, 67000, 83000 }).Name("Unique visitors");
})
.CategoryAxis(axis => axis
.Categories("Jan", "Feb", "Mar", "Apr", "May", "Jun")
.MajorGridLines(lines => lines.Visible(false))
)
.ValueAxis(axis => axis
.Numeric()
.Line(line => line.Visible(false))
)
.Tooltip(tooltip => tooltip
.Visible(true)
.Format("{0}")
)
)
@addTagHelper *, Kendo.Mvc
@{
var total_visits = new double[] { 56000, 63000, 74000, 91000, 117000, 138000 };
var unique_visitors = new double[] { 52000, 34000, 23000, 48000, 67000, 83000 };
var categories = new string[] { "Jan", "Feb", "Mar", "Apr", "May", "Jun" };
}

Animated Transitions
Telerik UI for ASP.NET Core Charts use animated transitions to display new and updated data. To disable these transitions, use the transitions option.
@(Html.Kendo().Chart()
.Name("chart")
.Transitions(false)
// Other options.
)
@addTagHelper *, Kendo.Mvc
<kendo-chart name="chart" transitions="false">
<!-- Other options.-->
</kendo-chart>
