Series Point Shape and Legend Shape

[Administrator]

Hi,
V4.4.0.51 & VS2005

I try to make my chart lines with different shape-point (such as cross,circle,diamond,rectangle,triangle etc) and the legend shape display a line with the same shape. The reason I want this is to make chart to be seen clearer when it is printed black-white.

I make a simple sample chart in Excel. How can I get the similar chart in ChartControl? It will be helpful if you have some sample.
Thanks,

Lan

Hi Lan,

My apologies for the delay in responding to you.

You can have the Legend Shape to be same as the Series shape as in the image sent by you by setting the Legend RepresentationType as SeriesImage and assigning the imageindex value for each legend.
The images should also be added to the ImageCollection of the Series before performing the above steps.

Kindly take a look at the code snippet below,

series1.Style.Images = new ChartImageCollection(this.imageList1.Images);
series2.Style.Images = new ChartImageCollection(this.imageList1.Images);

this.chartControl1.Legend.RepresentationType = ChartLegendRepresentationType.SeriesImage;
this.chartControl1.Legend.Items[0].ImageIndex = 0;
this.chartControl1.Legend.Items[1].ImageIndex = 1;

Also take a look at the attached sample.

Let me know if you have any queries.

Thanks & Regards,
Ramya.

Hi,
I am sorry I am developing in VS2003. I don't have VS2005 right now. Could you make your sample in VS2003?

Thanks,

Thank you very much. That is what I want.

One more quesion. Which property do I set to display the point value?

Hi Ramya,
when user customize series style, they may change the line color and shape as my attached file. The legend image line color and shape should change accordingly. This is difficult to dynamiclly change it because the legend image stored in ImageList is pre-fixed.
do you have any built-in function to automaticlly to display legend image with line's shape and color?

Hi Lan,

If your intention is to display the items of Legend with the shape same as that appearing along with the Line and with the color of the LegendItem's shape being same as the color of Line then it can be done as shown in the code snippet below,

this.chartControl1.Legend.Items[0].Type=ChartLegendItemType.Diamond;
this.chartControl1.Legend.Items[0].Interior=new Syncfusion.Drawing.BrushInfo(Color.Blue);

Also kindly take a look at the attached sample to get the above points in clear.

Let me know if I am wrong in getting your requirement.

Thanks & Regards,
Ramya.

That is very close.
I want to show both the shape and line. I also want to display the check box left to the legend image. I modified your code little bit as following.

this.chartControl1.Legend.RepresentationType = ChartLegendRepresentationType.Line;
//this.chartControl1.Legend.Items[0].Type=ChartLegendItemType.Diamond;
//this.chartControl1.Legend.Items[0].Interior=new Syncfusion.Drawing.BrushInfo(Color.Blue);
//this.chartControl1.Legend.Items[1].Type=ChartLegendItemType.Circle;
//this.chartControl1.Legend.Items[1].Interior=new Syncfusion.Drawing.BrushInfo(Color.Orange);

//this.chartControl1.Legend.VisibleCheckBox=true;
this.chartControl1.Legend.ShowSymbol=true;

The problem is when I turn set the this.chartControl1.Legend.VisibleCheckBox=true;

The legend shape will disappear. any ideas?

Thanks,

Lan

Hi Lan,

Both the shape and line can be displayed in the legend only by using images as in the sample sent by me on 30th January.

I was not able to reproduce the condition with regard to setting the this.chartControl1.Legend.VisibleCheckBox=true;

Kindly take a look at the attached screenshot.

Thanks & Regards,

Hi,
I found I can use following code to display both line and shape.

this.chartControl1.Legend.RepresentationType = ChartLegendRepresentationType.Line;
this.chartControl1.Legend.ShowSymbol=true;

I've modified your sample and attached here for your review.

The problem is when the Checkbox displays, the shape disappeared. I am not sure if it is a bug in chart control? In my revised sample, you can see it by clicking the 'Display/Hide checkbox' to toggle to display or hide the checkbox.
Thanks for help.
