MSChart - Multi-level master detail databinding doesn't work

Mon, 23 Nov 2009 08:35:13 Z

Hey!

I have 3 tables in master detail relation.

I dragged 3 tables to my form. VS2008 creates all controls automatically (binding sources, table adapters,... for each table)

Then I run the application and there is a working 3 level master detail example, but...

... in the 3rd table (detail) I have 2 columns (Timestamp and value). I want to bind table to chart control.
But it doesn't seems to work.
I tried 3 different chart controls:
- DevExpress.XtraChart --> works, but it has some issues on showing labels on X - axis
- TeeChart --> Wizard seems to support binding sources, but it can't find any members for XValueMember, YValueMemeber --> Comboboxes are empty)
- MSCharts --> No problems when setting Datasource, XValueMember,... but it doesn't work when I run application

            chart1.DataSource = null;
            chart1.DataSource = vrednostiBindingSource;
            //vrednostiBindingSource.MoveLast();
            //vrednostiBindingSource.MoveFirst();
            chart1.Series[0].XValueMember = "Cas";
            chart1.Series[0].YValueMembers = "Vrednost";

I must be doing something wrong, since datagrid is working OK (all 3 datagrids).

Any suggestions?

Thanks, [Beer]

Datapoint Marker Image and Color

Fri, 20 Nov 2009 18:09:19 Z

I've been fiddling around with this to no avail. I didn't see an example of what I'd like to accomplish in the interactive samples app. I'm hoping someone can shed some light on this.

I've got a chart with datapoints on it in several series. I'd like to display both a particular marker image AND a marker color simultaneously.

I can set the datapoint.MarkerImage to a NamedImage and that will display just fine.
I can also set the datapoint.MarkerImageTransparentColor to a color in that image and see that the specified color is replaced by transparency.

I'd like to set the datapoint's color based on some condition (assume the color is specified at runtime by the user) and then have both it AND the marker image displayed.

Example:

If the image were a black circle within a red square and I set the transparent color to black and the marker's color to green, I'd like it to result in a red square with a green circle (the image in front of the color).

I may just be overlooking something here.

Is this possible? If so, how?

Thanks,
Matthew

Tooltip on second series ignores format

Mon, 23 Nov 2009 06:15:54 Z

Hi everyone, hopefully this is something simply that I am doing wrong. I have a chart of a number of stacked columns. I want to have a tooltip display the value of each part of the column so I set Tooltip="#VALX: #VALYn{P2}" against series n. For the first series there is no problem. For subsequent series I get a 0 X label, and I get the Y value but not formatted and just with the string {P2} on the end (it appears to ignore the format. Is there anyway to get it to format the value? I have gotten around the 0 X label by setting the XValueType="String" for each n series.

Regards,

Mark.

where to set space between point on x axis - Column chart

Mon, 23 Nov 2009 05:04:20 Z

My chart code is below
        Chart1.Series["PV"].Points.DataBindXY(lDv, "state", lDv, "PV");
        Chart1.Series["PD"].Points.DataBindXY(lDv, "state", lDv, "PD");
        Chart1.Series["PV"].Points.DataBindXY(lDv, "state", lDv, "PVr");
        Chart1.Series["PDat"].Points.DataBindXY(lDv, "state", lDv, "PDat");

So what i have is a a group chart.

So i have a state e.g TX with 4 series PV,PD,PVr and PDat but on the chart the columns are grouped
but what do i need to do to have spaces between the grouped column.Now they are just all squized us side by side
Thanks in Advance

Chart design time property problem

Fri, 20 Nov 2009 05:57:18 Z

Hi everyone,

I am having a problem with the design time properties of charts. If I try and set properties using the propertygrid at design time they do not seem to render code in the Source view of the page (eg. I added a title to the chart, set the font name, size, bold=true but nothing showed in the Source view, not even that I added a title). I first thought this was something to do with being in an UpdatePanel but it also happens outside.

Am I missing something/doing something wrong? Has anyone else had this problem?

Just as an example, I dragged a chart onto my WebForm (with no other controls), I used the property view to add a Title to the chart. I checked the Source view and the <asp:Title> tag was there. I returned to Design view, added a Title to the x-axis of ChartArea1, went back to Source view and it was there. Back in design view, I used the property grid to try and set the font for the x-axis Title, back in Source view nothing (no change), back to design view changed the x-axis title and the font, back in Source view only the x-axis title had changed ... what is happening? Can't I used the propertygrid to set properties? If I try and add the tags in Source view the control just ignores them when the app runs.

Regards,

Mark

Chart.Text is not serialized

Sat, 21 Nov 2009 10:29:55 Z

I want to use the Chart.Text property as a place holder for a user defined chart description. But I see that when I set the Chart.Text property and then save as a serialization file it is not included. Two questions:
1. What is the purpose of this property?
2. How can I get the Chart.Text property to be saved and subsequently reloaded back in using the Save and Load Serialization methods respectively.
3. If Chart.Text cannot be serialized under any circumstances, can you suggest an alternate (custom) property I can use to persist a description in the serialization file for later use.

Help: Minimum and Maximum value in a segment of points

Sat, 21 Nov 2009 07:03:21 Z

Hello,

I am new to Chart Controls (great product by the way). I have a stock chart and when I show all the points I use the code below to set the max and min of Y axis 10% lower and higher than the lowest and highest point

DataPoint minPoint = stockChart.Series["Price"].Points.FindMinByValue();
DataPoint maxPoint = stockChart.Series["Price"].Points.FindMaxByValue();
double delta = (maxPoint.YValues[c_OHLC_high] - minPoint.YValues[c_OHLC_low]) * 10 / 100;
stockChart.ChartAreas["StockPrices"].AxisY.Minimum = minPoint.YValues[c_OHLC_low] - delta;
stockChart.ChartAreas["StockPrices"].AxisY.Maximum = maxPoint.YValues[c_OHLC_high] + delta;

Now my question: If I zoom in the chart the "StockChartAxisViewChanged" will be trigerred and I have e.NewPosition and e.NewSize that indicates which Points are visible. i.e. a segment of the Points collection.
I cant figure out what is the quickest way to recompute the min and max value inside the segment?
I will have sometimes 200,000 points in the segment
Obviously a "foreach" would do the job... But is there anything better? Like copying the segment into a new DataPointCollection and let "Chart Controls" compute Min and Max for me ?

Thanks in advance for your help and suggestions

No Data Message?

Fri, 23 Oct 2009 19:35:32 Z

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!

Series Points.DataBind not supported function?

Mon, 09 Nov 2009 22:45:28 Z

I am trying to use the Points.DataBind( ) function so that I can label the bars in the chart with a 3rd value, not the X or Y value. I have my data in a dataset and am needing to get it to an IEnumerable object, which the following seems to do.

IEnumerable myIEnum = myDS.Tables[0].AsEnumerable();
Chart1.Series[mySeriesName].Points.DataBind(myIEnum, XValueMember, YValueMember1, otherFields);

When I run this code I get an error:
Exception Details: System.NotSupportedException: Specified method is not supported.

Is it really not supported in .Net 3.5 or is something else wrong?

How to create column chart with fixed bar width

Fri, 15 May 2009 01:53:52 Z

I am using Microsoft Charting Controls for .NET 3.5 (System.Windows.Forms.DataVisualization.Charting). When I draw column chart, the width of the column bar is keep changing depends on the number of points. I tried with the following code to keep the width fixed.

chart1.Series["Series1"]["PointWidth"] = 0.6

This is also not helping me to fix the issue. The above line makes more gaps between the column bar. Is there a way to keep the column bar width and gap between columns are fixed.

Thanks,

MSChart

Thu, 19 Nov 2009 04:12:11 Z

I'm trying to learn mschart for Visual Basic 2008, is there any documents that explain any of the properties associated with this control? I have down loaded the MSChart.exe, MSCart_VisualStudioAddOn.exe and the WinSamples.. I start a new project add the chart control and insert the vbCode.txt from an example into the load event and press F5. Nothing changes on the form. Is there an example that contains a complete form that has all the data that should be displayed in the chart?

Chart Control Template Schema

Thu, 19 Nov 2009 14:48:46 Z

Hello,

Where can I find information about the chart template schema? What I'm looking for here is a complete list of what is valid in a template.

The basic idea I have is this. I have one xml template for a chart, I may add some custom nodes and attributes to this xml configuration file which will then be preprocessed by my code. Once the processing is complete an in memory representation of the xml file will be created which removes the custom nodes and attributes so the chart control can load the in memory template. So I need to know up front what the defined schema is...

Thanks for any advice you can offer.

x-axis span based on two series

Thu, 15 Oct 2009 19:09:12 Z

I have a couple of datasets being returned, each with a starting time point and and ending time point. One of the datasets might return 130 rows and the other more than 400. How do I configure a line chart to display Series 1 (with the first dataset values) and Series 2 (with the second dataset values) over this time span (x) together? I hope this makes sense. Oh, and the Series values are being added in code on the page load event.

Not all data is displaying in chart.

Fri, 13 Nov 2009 18:05:11 Z

I have a csv with about 2000 values, and the chart is displaying data outside the view. I allow the chart to be resized if the user wants to expand the windows form, and if I make the form really big, it displays all the values. Is there a way to compress the chartarea?

I need the user to be able to select the position of the bar chart because I take that position and draw a point of a map of the elevation location.

I also am getting errors with my data. Apparently the control is adding data that does not exist.

Thanks

A

Here is my code for creating the chart:
yValue1 is the list of elevations

Chart chart1 = new Chart();

double[] yValue1 = GetSeriesValues( url, path, filename);

// Create Chart Area

ChartArea chartArea1 = new ChartArea();

// Add Chart Area to the Chart

chart1.ChartAreas.Add( chartArea1 );

// Create a data series

Series series1 = new Series();

series1.ChartType = SeriesChartType.StackedColumn;//SeriesChartType.SplineArea;

for (int i = 0; i < yValue1.Length - 1; i++)

{

series1.Points.AddXY( i, yValue1[i] );

}

chart1.ChartAreas[0].AxisY.Title = "Elevation (meters)";

chart1.ChartAreas[0].BackGradientStyle = GradientStyle.LeftRight;

chart1.ChartAreas[0].AxisX.LabelStyle.Enabled = false;

chart1.ChartAreas[0].RecalculateAxesScale();

// Add series to the chart

chart1.Series.Add( series1 );

// Set chart control location

chart1.Location = new System.Drawing.Point( 0, 0 );

// Set Chart control size

chart1.Size = new System.Drawing.Size( 360, 260 );

chart1.Dock = DockStyle.Fill;

chart1.Series[0].IsXValueIndexed = false;

// Set Border Color

chart1.BorderColor = Color.Blue;

// Set Border Style

chart1.BorderDashStyle = ChartDashStyle.Solid;

// Set Border Width

Print graphics faster

Thu, 19 Nov 2009 12:00:42 Z

Hi all.

To print a chart, I have created a new chart (like WinFormsChartSample shows) based to original chart.
The original graph is a DateTime-Value chart that has about 90000 points.

Since the new chart must be exacty than the original chart, except the Chart.BackColor and Series.ForeColor I have used the next code

originalChart.Serializer.Content = SerializationContents.Data
originalChart.Serializer.SerializableContent = "*.*"
originalChart.Serializer.Save("Graphic.txt")

and the new graph spends, at least, 10 minutes to be previewed.

If the original graph has about 10000 points, the new graphic is visible in less than 1 minute.

Somebody knows a way to accelerate the creation of a new graphic almost equal than the original?

Thanks in advance.
