Hi.

My ' MultiVerticalAxis' is setted <Setter Property="Stroke" Value="{Binding Converter={StaticResource seriesColorConverter}}"/>.

In converter,

axis.Title = obj.Unit;
axis.Maximum += 0.5;
axis.Minimum += -0.5;
axis.LineStroke = new SolidColorBrush(Colors.White);
axis.Foreground = new SolidColorBrush(Colors.White);
axis.FontSize = 11;

In this picture, I want to rotate 'Title Font'

What should I do??

Timeline view scrolling with out zooming?

Hello,

I want to set the timeline viewing slot to either 1 or 5 days and instead of having all 5 days compressed into the same area, I would like to have just be able to scroll to the different days with the timeslots as the same width.

What settings do I need to set to enable this?

Thanks!
Ryan

How to plot error bar for standard deviation?

Hi Telerik,

Is it possible for me in WPF to plot an error bar representing the standard deviation?

I want it to look similar to the error bars found here http://demos.telerik.com/kendo-ui/dataviz/line-charts/error-bars.html

Best regards,
Jeppe

Collapsing DateTimeCategoricalAxis still reserves space

I have a problem where collapsing a DateTimeCategoricalAxis is still reserving space in the UI. It is being used as the Horizontal axis, and is reserving Width but not Height. The below example shows the problem.

Note that the display looks correct initially, with both graphs going to the edge of the windows. Now use the checkbox to enable the horizontal display on the bottom chart, which switches the Visibility on the Axis from Collapsed to Visible. The chart displays correctly. Now uncheck the checkbox, which changes the Visibility back to Collapsed. Now notice the chart has about an inch of white-space on either side of the graph. The Height collapsed correctly, but the Width did not.

Is there any way of getting the Axis to resize correctly after being Collapsed short of replacing the Axis completely (see the commented code)?

This was tested with 2014.1.331.45.

Thanks,
Louis

Icon for RadWindow

I have replaced several of my dialog forms with RadWindow form in my WPF application and the Application Icon that used to show on the dialogs don't seem to show on the RadWindow. I have tried a lot of different ways of getting the Icon to show including the following:

if (((System.Windows.Controls.Canvas)this.Parent).Parent is Window)

{

Window thisWindow = ((System.Windows.Controls.Canvas)this.Parent).Parent as Window;

thisWindow.ShowInTaskbar = true;

thisWindow.Title = this.Header.ToString();

this.Icon = thisWindow.Icon;

}

The Icon shows in the taskbar correctly, but nothing is shown on the RadWindow itself. Is there something I am doing wrong? Some setting someplace that I am missing that will make it magically show it?

I tried:

Uri iconUri = new Uri("pack://application:,,,/WPFIcon2.ico", UriKind.RelativeOrAbsolute);

this.Icon = BitmapFrame.Create(iconUri);

and I get the text "pack://application:,,,/WPFIcon2.ico" where the Icon should be.

I even tried creating a System.Drawing.Icon object and setting it to that and it just puts "(Icon)" in the corner of the form.

I have nothing in the XAML that refers to the Icon property for the window. I assumed that the RadWindow type would automatically get the icon from the application, but I have not found any setting on the control that turns on or off the displaying of the icon.

PanelBar and MVVM

Hello everyone.

I am playing around with MVVM (leveraging Prism and Unity), but I am somewhat stuck on how to bind my modules to a PanelBar properly. What I want to do is set the ItemHeader text to the name of whatever module I am loading (at design time, I don't know how many modules will be loaded), and then have the Items (Views) be displayed under that. Graphically it would look something like this:

################ PanelBar ###############
================Module 1 Text=============== //ItemHeader
---------------------------- View 1 Text--------------------------- //Item
---------------------------- View 2 Text--------------------------- //Item
---------------------------- View 3 Text--------------------------- //Item
================Module 3 Text=============== //ItemHeader
---------------------------- View 1 Text--------------------------- //Item
---------------------------- View 2 Text--------------------------- //Item
##########################################

I know (basically) how to get 'View X Text' to display through the use of a ViewModel, but I am not sure about getting the ItemHeader set properly. Any help that you can provide would be greatly appreciated!

Thanks.

Binding IsMinimized with dynamic ribbon content breaks

We're using the RadRibbonView and are populating it's content dynamically using models for tabs, groups, and buttons. In the constructor of our window we initialize some default tab for the ribbon and make it selected. Then after the window has been loaded we add some more ribbon tabs based off a certain configuration. By itself this works just fine. However we've now decided to bind the RadRibbonView.IsMinimized property so that we can change it in code (get/set from config class). This also works fine by itself, but when you combine these two usage behaviors the RadRibbonView kind of breaks on initial start. You can download a sample project that demonstrates the problem here: https://dl.dropboxusercontent.com/u/22608/RibbonViewMinimized.zip

It seems to be related to the tab selection. In the constructor of the MainWindow if you remove the line that sets the initially selected tab then the problem goes away. Otherwise the SelectedTabContent component of the RadRibbonView seems to become detached from the window (if you move the window around the screen after it initially loads you'll see what I mean). Also, after the window is displayed and the ribbon view is broken, toggling IsMinizmied (double-clicking on a tab header) fixes the issue.

There's things we can do to easily work around this, but I just wanted to present it as a bug and see if you had any feedback.

Thanks!
