Issues with date/time data for column charts

[Administrator]

I am attempting to display date/time along an X axis, quantity of 'events' on the Y.


Here's the pertinent bit from InitializeComponent()
//
// cht
//
//
//
//
this.cht.Legend.IsWindowLess = false;
this.cht.Legend.Location = new System.Drawing.Point(675, 42);
this.cht.Legend.TabIndex = 1;
this.cht.Legends.Add(this.chtAuditEvents.Legend);
this.cht.Location = new System.Drawing.Point(220, 576);
this.cht.Name = "cht";
this.cht.Size = new System.Drawing.Size(768, 112);
this.cht.TabIndex = 91;
//
//
//
this.cht.Title.Name = "Def_title";
this.cht.Title.Size = new System.Drawing.Size(8, 8);
this.cht.Title.TabIndex = 2;
this.cht.Title.Visible = false;
this.cht.Titles.Add(this.cht.Title);
this.cht.ToolBar.ButtonFlatStyle = System.Windows.Forms.FlatStyle.Popup;



I add this data (8:20/2, 8:21/4, 8:22/4, 8:23/17) in the format of DateTime (dtStart)/long (lEventQty) to a series:

seriesProcess.Points.Add(dtStart, lEventQty);

At the conclusion of creating that series, we set the type and add it to the chart:

seriesProcess.Type = ChartSeriesType.Line; this.cht.Series.Add(seriesProcess);

this.cht.PrimaryXAxis.ValueType = ChartValueType.DateTime; this.cht.PrimaryXAxis.DateTimeFormat = "hh:mm"; cht.PrimaryXAxis.LabelRotate = true; cht.PrimaryXAxis.LabelRotateAngle = 45;

When the series type is set to 'ChartSeriesType.Line', everything displays properly. When the type is set to 'ChartSeriesType.Column' I get what appears to be a very odd display (see attachment) of the information; does anyone have some insight on why the grid is acting so oddly?

Best,

Hi Drew,

We regret very much for the delayed response.

I have tested for this issue in Version 6.1.0.34 and was able reproduce this issue. However I am glad to inform you that this issue has been fixed in our later version (from version 6.2.0.40 and above).

You can download the later versions from the following link.

http://www.syncfusion.com/downloads/product/versionhistory.aspx

Unlock key:

If your Essential Studio license is current, you will be able to obtain the key to install this version from your account in DirectTrac. Otherwise, please contact your Syncfusion Sales Representative or e-mail [e-mail]

However it also is possible to overcome this issue by setting the ColumnWidthMode of ChartControl to FixedWidthMode. Please refer to the sample code below.

this.chartControl1.ColumnWidthMode = ChartColumnWidthMode.FixedWidthMode;
this.chartControl1.ColumnFixedWidth = 20;

I have also attached the sample that illustrates the same in this link below.

Kindly let us know if this helps in resolving your problem. Thanks for your patience.
