Why do you need a 64bit JET OLEDB provider?

You can Provide Multiple Y values per X Axis. Try looking into that.

Hi All,

I have been playing around with the new ASP.NET chart control and really like it. I am having a bit of trouble dynamically building a new charts for each item choosen in a check box list. The code below works only if one item is selected from the checkbox list. If more than one item is selected it errors out. Is it because of the way I am creating the object?

Dim choice As ListItem

For Each choice In QSColumn_CBL.Items
If choice.Selected = True Then
'Build a SQL based upon the current value in the loop and set the SQLDataSource Control
GraphDS.SelectCommand = "My Dynamic Statement Here - This Works..."

'Create chart
Dim MyChart As New Chart()
MyChart.Titles.Add(choice.Text & " Chart")
MyChart.DataSource = GraphDS
MyChart.Width = 800
MyChart.Height = 500

'Format the column name for the XValueMember
Dim colname As String
colname = choice.Value.ToString.Substring(choice.Value.ToString.IndexOf(".") + 1, choice.Value.ToString.Length - choice.Value.ToString.IndexOf(".") - 1)

'Create chart Series
Dim MySeries As New Series
MySeries.Name = choice.Text
MySeries.XValueMember = colname
MySeries.YValueMembers = "Count"
MySeries.IsValueShownAsLabel = True
MySeries.ChartType = SeriesChartType.Bar
MyChart.Series.Add(MySeries)

'Create chart Area
Dim MyChartArea As New ChartArea
MyChartArea.AxisX.Interval = 1
MyChart.ChartAreas.Add(MyChartArea)
MyChart.BorderSkin.SkinStyle = BorderSkinStyle.FrameThin2

'Create a new DIV for each chart
Dim MyPan As New Panel
MyPan.Controls.Add(MyChart)
'Add the chart into the place holder
ChartPlaceHolder.Controls.Add(MyPan)

End If
'Go to the next selected value and build another chart
Next

This is the error Im getting when more than one column is selected from the checkbox list

"Column with name 'Model' was not found."

Its like its not changing the XvalueMember for the next selected item...
Thanks for any advise!

NEW POST: Creating Stock Charts using MS Chart

Aatif — Thu, 05 Nov 2009 12:54:28 GMT

I want to create a stock chart which will be updated periodically, but I am unable to figure out how will I provide the Candlestick values like 'open', 'close', 'high' 'low' etc ...

from the WinForm examples, I found the following lines of code;

----------------------

// Set series chart type
chart1.Series["Price"].ChartType = SeriesChartType.Candlestick;

// Show both open and close marks
chart1.Series["Series1"]["ShowOpenClose"] = "Both";

// Set the style of the open-close marks
chart1.Series["Series1"]["OpenCloseStyle"] = "Line";

----------------

thanks in advance for any help or example code.

NEW POST: Bar + Plot series

Alvy — Tue, 03 Nov 2009 17:41:21 GMT

H guys,

I have been using the MSChart control to try and reproduce the visuals I've been given for a type of graph in an application I'm working on. The graph looks like this:

http://www.haushinka.org/media/example_graph.jpg

There are essentially three series running in parallel - one is the "current" value, marked as a bar chart, and the other two are projected and target series, displayed as plot charts.

Due to the bar chart having the axis' reversed, it appears to not like me combining the two types together - I get exceptions along the lines of "One or more charts cannot be used in conjunction."

I have been looking at potentialy using the Pre/PostPaint evets to draw the projected and target series, though it's a bit of a dirty hack.

Any ideas on a solution to being able to get these two types of data displayed together?

Regards,
Alvaro

NEW POST: A little bug on HistogramChartHelper.cs

Kaye — Tue, 03 Nov 2009 09:07:39 GMT

Hi,

I am using Microsoft Chart Controls, think this is very useful. Thank you for your developing.

I have read 'HistogramChartHelper.cs', i think there is little bug about the settting of AxisY2.
I am afraid you have enlarged this value by 100 times.......
(Line 185 ~ 187, or change the format of AxisY2 in Line 180)

For example, in your download-samples:
Chart types - Data distribution Charts - Histogram chart
the percentage of total, will show 1000%, 2000%, etc.
But in the real world it cannot exceed 1 (100%). Right?

NEW POST: OWC xml to MSChart

Vapordan — Thu, 29 Oct 2009 12:51:15 GMT

I'm not sure what you are trying to do here but if you want to import data, you'd first need to serialize it from the OWC. Chart1.XMLDATA should allow you to extract the data. You can then persist it to a file or stream and use that stream to feed the server via a webservice or web method. Once the server method executes, you can create code inside that method to bind to XML data in the regular way.

Wouldn't it be easier to bind to the data file that OWC uses instead of trying to bind to the OWC object?

I've been running this on Windows 7 x64 and there are several pages that do not work because there is no 64-bit JET OLEDB provider.

NEW POST: Aligning Shapes with Chart Areas

RubberDuckMW — Wed, 28 Oct 2009 06:03:52 GMT

Hi,

I am looking to draw a set of lines and shapes underneath a MSchart object. My problem is aligning the lines and shapes with the chart. I can access the Chart size (in pixels) and the ChartArea size (as a percentage of the Chart size), that is fine. But i can't access the exact length of the x-axis in pixels or percentage of the ChartArea. This proves problematic when the y-axis and its corresponding labels are constantly resizing.

Any help would be greatly aprreciated,
Thanks

NEW POST: No Data Message?

tombalak — Mon, 26 Oct 2009 09:29:24 GMT

The code below may be helpful.

Chart _ch;

NoDataWarning = true;

ch.PostPaint += new EventHandler<ChartPaintEventArgs>(ch_PostPaint);

...

void chPostPaint(object sender, ChartPaintEventArgs e)
{
if ((sender is Chart) && NoDataWarning)
{
Chart chrt = (Chart)sender;

// Get Graphics object from chart
Graphics graph = e.ChartGraphics.Graphics;

StringFormat strFormat = new StringFormat();
strFormat.Alignment = StringAlignment.Center;
strFormat.LineAlignment = StringAlignment.Center;
graph.DrawString("No data", new Font(main.DefaultFont, main.DefaultFont.Style), Brushes.Black,
new RectangleF(0, 0, chrt.Width, chrt.Height), strFormat);
}

}

NEW POST: No Data Message?

bharring0107 — Thu, 22 Oct 2009 17:26:39 GMT

What's the best way to display a message across the front of of a chart, in case no data points are loaded? Sort of like a "This Page Intentionally Blank" type messge. I don't see something in the API like setNoDataMessage(). If I did this manually, how best to stamp a bold title-like statement across the front of the chart?

Thanks!

NEW POST: OWC xml to MSChart

rageit — Wed, 14 Oct 2009 04:36:13 GMT

Hi,

Is there any way to map/import xml generated from OWC to MSChart? I've searched the net in vain. If anyone has any idea on how this can be accomplished or if there is any easier means then I'd be glad if its shared.

Regards
