Bar width & Average line

[Ajith Nair]

Hi All,

I have 2 queries regarding the chart.

1)  In my application I have a bar chart. Is there any way to decrease the bar width.(or the scale width)

2) I have a line chart with hours in the Y-Axis and Date in the x-Axis. Is there any way to draw a vertical line so that I can display the average hours of that chart.

Thanks in advance
Ajith

Hi Ajith Nair,

Onto your questions:

• You can control the bar width through the ChartSeries.Appearance.BarWidthPercent property (value 0 - 100).
• The control does not provide built-in support for custom gridlines, but you can use the MarkedZones feature to achieve similar effect (you will need to set really small width for the marked zone to look like gridline):

ChartSeries series = new ChartSeries();
series.Type = ChartSeriesType.Line;
series.AddItem(10);
series.AddItem(20);
series.AddItem(30);

RadChart1.Series.Add(series);

ChartMarkedZone markedZone = new ChartMarkedZone();
markedZone.ValueStartX = 2;
markedZone.ValueEndX = 2;
markedZone.ValueStartY = 0;
markedZone.ValueStartY = 30;
markedZone.Appearance.Border.Width = 1;
markedZone.Appearance.Border.Color = Color.Red;

RadChart1.PlotArea.MarkedZones.Add(markedZone);

Hello Telerik Team,

I would like to know how can I set the border color of the item of a Serie, for example, in a Bar Serie.

I send a picture and you know what I mean.

Thank you very much,

Kind regards,

Alfonsina.

Hi Alfonsina,

 You can either set Border for the whole serie or for an item of it. Here's how to set Border for all items of your first serie:

RadChart1.Series[0].Appearance.Border.Color = Color.Yellow;
RadChart1.Series[0].Appearance.Border.Width = 3;

To provide color for a single item (the second bar in this case) you should do the following:

RadChart1.Series[0].Items[1].Appearance.Border.Color = Color.Red;
RadChart1.Series[0].Items[1].Appearance.Border.Width = 3;
