+## Description
+
+This KB article answers the following questions:
+
+* How to draw horizontal and vertical lines in Telerik Blazor Charts?
+* How to put pins or markers in Telerik Blazor Charts?
+* Is it possible to add limits or thresholds on the Telerik Blazor Chart?
+
+## Solution
+
+To configure the Chart for drawing horizontal and vertical lines, you can use [plot bands]({%slug chart-plot-bands%}) or additional [line series]({%slug components/chart/types/line%}).
+
+### Using Plot Bands
+
+Steps for drawing vertical and horizontal lines with [plot bands]({%slug chart-plot-bands%}):
+
+1. Add `PlotBand` instances inside the `PlotBands` collection of a Chart axis.
+2. Provide a valid CSS color to the `Color` parameter.
+3. [Set the `From` and `To`]({%slug chart-plot-bands%}#setting-from-and-to) plot band parameters.

+ SeriesData = new List();
+
+ var rnd = new Random();
+
+ for (int i = 0; i < 60; i++)
+ {
+ SeriesData.Add(new ModelData
+ {
+ Strength = rnd.Next(-90 + i / 3, -90 + i),
+ Errors = rnd.Next(i / 20, i / 3)
+ });
+ }
+
+ base.OnInitialized();
+ }
+
+ public class ModelData
+ {
+ public double Strength { get; set; }
+ public double Errors { get; set; }
+ }
+ #endregion
+}

+
+### Using Additional Line Series
+
+Steps for drawing horizontal and vertical lines with additional [Lines Series]({%slug components/chart/types/line%}):
+
+1. Add `ChartSeries` instances of type `ChartSeriesType.Line` based on the needed number of lines.
+2. Set data for the lines based on the information shown from the main Chart.
