Asked On January 7, 2008 03:13 PM

Hi, I was wondering if you can help me out. I would like to make a line chart that would display the following data:

Apple: 25
Orange: 45
Peach: 75
Grape: 15
Pear: 112

I would also like each item to have a different color. Can you please provide an example how I can do this.

Thanks

Hi Michael,

Thank you for using for Syncfusion products.

We can give different colors to each of the items by passing the values for label name, color, font and ChartValueType parameters to the PrimaryXAxis's Label method. Please refer to the code snipept given below:

this.chartControl1.PrimaryXAxis.ValueType = ChartValueType.Custom;
this.chartControl1.PrimaryXAxis.TickLabelsDrawingMode = ChartAxisTickLabelDrawingMode.UserMode;
this.chartControl1.PrimaryXAxis.Labels.Clear();
this.chartControl1.PrimaryXAxis.Labels.Add(new ChartAxisLabel("Apple", Color.Crimson, new Font("Monospace", 11), 0, "", ChartValueType.Custom));
this.chartControl1.PrimaryXAxis.Labels.Add(new ChartAxisLabel("Orange", Color.Blue, new Font("Monospace", 11), 1, "", ChartValueType.Custom));
this.chartControl1.PrimaryXAxis.Labels.Add(new ChartAxisLabel("Peach", Color.LightBlue, new Font("Monospace", 11), 2, "", ChartValueType.Custom));
this.chartControl1.PrimaryXAxis.Labels.Add(new ChartAxisLabel("Grape", Color.GreenYellow, new Font("Monospace", 11), 3, "", ChartValueType.Custom));
this.chartControl1.PrimaryXAxis.Labels.Add(new ChartAxisLabel("Pear", Color.Crimson, new Font("Monospace", 11), 4, "", ChartValueType.Custom));


Kindly have a look into the simple sample available in the link below that illustrates the same:

Sorry, when I said line chart, I really meant Bar Chart. Your example did help a little, but I would like to set a different color for each bar (not the label at the bottom). I tried to create a different Series for each object but that doesn't work correctly.

Thanks

Hi Michael,

Sorry for the inconvenience caused.

We can give different colors to each of the bars by handling ChartPrepareStyleInfoHandlerEvent. Please refer to the code snippet given below:

void series_PrepareStyle(object sender, ChartPrepareStyleInfoEventArgs args)
{
ChartSeries series = sender as ChartSeries;
if (series != null)
{
if (args.Index == 0)
args.Style.Interior = new Syncfusion.Drawing.BrushInfo(Color.Red);
else if (args.Index == 1)
args.Style.Interior = new Syncfusion.Drawing.BrushInfo(Color.Green);
else if (args.Index == 2)
args.Style.Interior = new Syncfusion.Drawing.BrushInfo(Color.Blue);
else if (args.Index == 3)
args.Style.Interior = new Syncfusion.Drawing.BrushInfo(Color.Yellow);
else if (args.Index == 4)
args.Style.Interior = new Syncfusion.Drawing.BrushInfo(Color.Aqua);
}
}


Kindly have a look into the sample available in the link below and let me know if it helps:
