OxyPlot : ColumnSeries/BarSeries display value of each column - wpf

In my WPF app, I use OxyPlot. I bind my data to the PlotModel and all is working well.
I want to display the value of each column on the chart. Is it possible?
For reference, this example of BarSeries on site, I wish to show actual value of Apples of 2009, 2010 & 2011 respectively on each column. i.e. value of Value1 for the 2009Apples column, Value2 for 2010Apples and so on.
I looked up at the APIof the BarSeries (For WPF ColumnSeries used interchangeably).
Tutorials of Bar & other plots. But couldn't find such thing anywhere.
How do I achieve this?

Yes, just set the LabelFormatString property of your series.
var theSeries = new ColumnSeries();
theSeries.LabelFormatString = "{0:F2}"; // Example: 1.2311 will display like "1.23"
// Add your columns
theSeries.Items.Add(new ColumnItem(someValue);
// ...
There is also an optional property you can set called LabelPlacement. The default value is LabelPlacement.Outside:
theSeries.LabelPlacement = LabelPlacement.Middle;

ComboBox with Vaadin Grid and ComponentRenderer and the Empty Grid

I hope this post can help me.
My problem that when I use ComponentRenderer, then the grid appears empty.
The used vaadin version 7.6 and the used ComponentRenderer is 1.0.3 as it is recommended to be.
If I did not use ComponentRenderer, then the grid appears but the combo box is not appear.
What could be the reason?
Below is the used code:
Object itemId = container.addItem();
container.getContainerProperty(itemId,"ID").setValue("1");
container.getContainerProperty(itemId,"Dependent MPI").setValue("200.300");
container.getContainerProperty(itemId,"MPI Type").setValue("Antenna");
container.getContainerProperty(itemId,"Approval").setValue(ApproveReject);
this.getColumn("Approval").setRenderer(new ComponentRenderer());
Regards
Bilal
Object itemId = container.addItem(); //1
container.getContainerProperty(itemId,"ID").setValue("1");//2
container.getContainerProperty(itemId,"Dependent MPI").setValue("200.300");//3
container.getContainerProperty(itemId,"MPI Type").setValue("Antenna");//4
container.getContainerProperty(itemId,"Approval").setValue(ApproveReject);//5
this.getColumn("Approval").setRenderer(new ComponentRenderer()); //6
I believe you are trying to add a column "Approval" in line 5. Shouldn't it be:
Column approvalColumn = container.addColumn(...);
approvalColumn.setRenderer(...);

How can I vertically center a value in a PivotTable cell with Aspose Cells?

I know how to vertically center cell values when they can be defined by their row location, namely get a reference to them, create a style, assign values to the style, and then assign the style to the cell, like so:
cell = pivotTableSheet.Cells[4, 0];
cell.PutValue(AnnualContractProductsLabel);
style = cell.GetStyle();
style.HorizontalAlignment = TextAlignmentType.Center;
style.VerticalAlignment = TextAlignmentType.Center;
style.Font.IsBold = true;
pivotTableSheet.Cells.SetRowHeight(4, 25);
style.BackgroundColor = CONTRACT_ITEM_COLOR;
pivotTableSheet.Cells[4, 0].SetStyle(style);
But what about for recurring values, such as those that are generated for a PivotTable?
I create a row value like so:
pivotTable.AddFieldToArea(Aspose.Cells.Pivot.PivotFieldType.Row, DESCRIPTION_COLUMN);
pivotTable.RowHeaderCaption = "Description";
...which appears like this (the values beneath "Description" such as "Anise, *" and "Artichokes, *", "Asparagus, *" etc.):
I want those values vertically centered, rather than at the top. How can I manage that?
If you do any formatting with the pivot table cell, then please create a Style object and then call this method. It should fix your issue.
mPivotTable.Format((2, 4, style);

comboBox -- saving valueMember but showing displayMember

Just starting to use VS2013. Have several projects that I am porting from older technology. This should be really simple, so I am sure I am missing something easy.
The combo box is used to build a record. There is an ID field and a Description field. Very simple. I am trying to show the Description (which is text), but save the ID (which is int).
DataSource = table1BindingSource
DisplayMember = Description
ValueMember = ID
Databinding.Text = table2BindingSource.field1
I have tried setting
Databinding.SelectedValue = ID
and
Databinding.SelectedItem = ID
It displays in the dropdown correctly. It displays in the field correctly, using the Description. But value must not be associated with the field correctly, because I cannot save or move to the next record. Looks like the Description is getting put in the field1, and as it is int, it is not accepting it.
What am I missing?
I got it. For text boxes, I had been assigning
DataBinding.Text = Table1.field
So, I was trying to assign for combo boxes
DataSource = Table1
DisplayMember = Table1.description
ValueMember - Table1.code
and
DataBinding.SelectedValue = Table1.code
DataBinding.Text = Table2.field
I finally removed the Text statement and assigned
DataBinding.SelectedValue = Table2.field
And it all worked as desired.

How to set displaymember in code-behind?

XAML
<ComboBox Height="23.338" x:Name="cboCustom" />
Code which runs when the combobox should be populate
cboCustom.Items.Clear()
For x As Integer = 0 To (_collection.count - 1)
cboCustom.Items.Add(_collection.node(x))
Next
The _collection.node() is class with several properties
And I would like to set the displayMembervalue of the WPF combobo to it's description property.
I've tried
cboCustom.DisplayMemberPath = "myitem.description"
and
cboCustom.DisplayMemberPath = "description"
With no luck.
cboCustom.SeletedItem.description (on select action) does however give me the expected value.
Just use "Description" on its own (assuming that's the name of the property you want to display). Also, make sure the casing is correct.

How could I create a Gantt-like chart in a datawindow (Powerbuilder)

I want a rather simple (and cheap) solution, just for presentation purposes (and just to show the task duration bars - no connection lines between them). So, I am not interested in buying some advanced custom control like this for example. Have any of you ever used something like this? Are there any code samples available?
I would have pointed to Buck Woolley's dwExtreme site for an example of how to do a gantt in native DataWindow. However, "simple" I don't think is in your future if you want to roll your own. In fact, I'll be pleasantly surprised if someone writes a posting that includes a full description; I think it would take pages. (I'd be happy if someone proved me wrong.) In the meantime, here are some DataWindow basics I think you would need:
You can create an external DataWindow whose data source is not tied to a table
Columns in the data set do not have to be shown on the user interface
Columns in the data set can be used in expressions to evaluate attributes, so you could have a column for each of the following attributes of a rectangle:
x
width
color
I'd expect this to be a lot of work and time, and very likely to be worth the purchase the component (unless your time is valued at next to nothing, which in some IT shops is close to true).
Good luck,
Terry

You can make a simple Gantt chart with a Stacked Bar Graph (BarStacked (5) in the painter). The trick is to create a dummy series to space the bar out where you want it and make the dummy bar the same color as the graph's background (BackColor). It turns out you also need another dummy series with a small value to sit on the axis. Otherwise when you change the color of the bar that's doing the spacing, the axis line gets cut off. I found that .04 works well for this value.
Create the DataWindow
(This assumes familarity with the DataWindow Wizard. Refer to the PowerBuilder User's Guide for more information on creating graphs in DataWindows)
Click the icon for the new object wizard. Create a Graph DataWindow with an External data source. Create columns task type string(20), ser type string(1), and days type number. Set the Category to the task column and the Values to the days column. Click the Series button and select ser for the series. Don't bother with the title, and select the Stacked Bar graph type. When the painter opens, save the DataWindow. On the General tab in the Painter, change the Legend to None (0). On the Axis tab, select the Category axis, then set the sort to Unsorted (0). Select the Value axis then set the sort to Unsorted (0). Select the Series axis and set the sort to Ascending (1). Save the DataWindow.
Create the Window
Create a window and place a DataWindow control, dw_1. Set the data object to your graph DataWindow. Place the following in the open event (or pfc_postopen if using PFC).
try
dw_1.setRedraw(FALSE)
// LOAD DATA HERE
dw_1.object.gr_1.title = 'Project PBL Pusher'
dw_1.object.gr_1.category.label = 'Phase'
dw_1.object.gr_1.values.label = 'Project-Days'
catch (runtimeerror re)
if isvalid(gnv_app.inv_debug) then gnv_app.inv_debug.of_message(re.text) // could do better
finally
dw_1.setRedraw(TRUE)
end try
You would load the data for your chart where the comment says // LOAD DATA HERE
Script the graphcreate Event
Add an new event to dw_1. Select pbm_dwngraphcreate for the Event ID. I like to name these events by removing the pbm_dwn prefix so I use graphcreate. Add the following code to the event.
string ls_series
long li_color
try
li_color=long(dw_1.object.gr_1.backcolor)
// note first series is a dummy with a small value (0.04 seems to work) to keep the line from being hidden
ls_series = dw_1.seriesName("gr_1", 2)
if 0 = len(ls_series) then return // maybe show error message
// will return -1 when you set color same as the graph's backcolor but it sets the color
dw_1.setSeriesStyle("gr_1", ls_series, BackGround!, li_color) // the box
dw_1.setSeriesStyle("gr_1", ls_series, ForeGround!, li_color) // the inside
catch (runtimeerror re)
if isvalid(gnv_app.inv_debug) then gnv_app.inv_debug.of_message(re.text) // could do better
end try
Data for the Graph
Load the data with the categories in the reverse order of what you want. For each Task, insert 3 rows and set the series to a, b, and c, respectively. For series a in each task, set a small value. I used 0.04. You may have to experiment. For series b in each task, set the number of days before start. For series c, set the number of days. Below is the data in the sample DataWindow.
Task Ser Days
---- --- ----
Test a 0.04
Test b 24
Test c 10
Develop a 0.04
Develop b 10
Develop c 14
Design a 0.04
Design b 0
Design c 10
