Questions

Hi Guys

We’re adding legends to out charts and would prefer to have horizontal legends rather than vertical ones. We are using data templates for the charts requiring the use of styles for the change rather than doing it programatically.

I had a look at the forum topics on the subject and set up a style with a horizontal stack panel like this

        <Style x:Key="LegendStyle"
               TargetType="{x:Type visuals:SciChartLegend}">
            <Setter Property="BorderBrush"
                    Value="White" />
            <Setter Property="BorderThickness"
                    Value="0" />
            <Setter Property="Background"
                    Value="{DynamicResource ComponentColor}" />
            <Setter Property="VerticalAlignment"
                    Value="Top" />
            <Setter Property="HorizontalAlignment"
                    Value="Left" />
            <Setter Property="Padding"
                    Value="5" />
            <Setter Property="FontSize"
                    Value="12" />
            <Setter Property="Foreground"
                    Value="Black" />
            <Setter Property="FontWeight"
                    Value="Bold" />
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type visuals:SciChartLegend}">
                        <Border x:Name="PART_Border"
                                BorderBrush="{TemplateBinding BorderBrush}"
                                BorderThickness="{TemplateBinding BorderThickness}"
                                Background="{TemplateBinding Background}"
                                HorizontalAlignment="{TemplateBinding HorizontalAlignment}"
                                Padding="{TemplateBinding Padding}"
                                VerticalAlignment="{TemplateBinding VerticalAlignment}">

            </Grid>
        </DataTemplate>

Unfortunately the style does not seem to get applied to the legend. Even without the new stackpanel the style is not applied. Without the Style setting in the Legend the legend appears normally but vertically oriented of course.

Any thoughts as to the issue?

Thanks in advance

I’m developing an application where I need to generate a series of small chart “thumbnails” in a window. When the user clicks one, an equivalent full size chart is displayed in a separate window. There are several different types of chart (different data, interactivity, etc).

The thumbnail charts are quite small and have minimal formatting (e.g. no axis titles, grid lines, and so on), while the full size charts have more visual elements, and interactive functionality including modifiers, context menus, and other mouse event handlers. For this reason I’ve been using separate XAML for each chart’s thumb and full size version, but having two versions for each chart is becoming a maintenance issue as new chart types are added.

Certain elements are pretty similar between the two – particularly the and the (and YAxis), and I was wondering if there was a way to make these into resources, or if you can suggest some other way to achieve what I’m trying to do (i.e. XAML re-usability!).

I tried creating a resource dictionary with a style targeting “SciChartSurface”, then adding a setter for “RenderableSeries”, but it doesn’t like that as it’s an ObservableCollection.

Hi there,

In the application we are developing, a user has the ability to add his/her own text annotation to the chart. Its simply done on the code behind, as its not persisted, so its really simple.

The code we use to add the user text annotation is:

    private void AddTextAnnotationExecute(object obj)
    {
        var yValue = YAxis.HitTest(MousePoint);
        var xValue = XAxis.HitTest(MousePoint);

        var textAnnotation = new TextAnnotation
        {
            CanEditText = true,
            IsEditable = true,
            IsEnabled = true,
            Text = xValue.DataValue.ToString(),
            X1 = xValue.DataValue,
            Y1 = yValue.DataValue,
            YAxisId = YAxis.Id,
            Uid = Guid.NewGuid().ToString(),                
        };

        _sciChartSurface.Annotations.Add(textAnnotation);

        foreach (var annotation in _sciChartSurface.Annotations.Cast<AnnotationBase>().Where(c => !string.IsNullOrEmpty(c.Uid)))
        {
            annotation.IsEditable = true;
        }

        _customAnnotationCollectionList.Add(textAnnotation);
    }

This is the style we apply to the text annotation:

<Style TargetType="sciChart:TextAnnotation">
        <Setter Property="BorderBrush" Value="Gray"/>
        <Setter Property="Background" Value="White"/>
        <Setter Property="Foreground" Value="Black"/>
        <Setter Property="FontFamily" Value="Segoe UI"/>
        <Setter Property="FontSize" Value="12"/>
        <Setter Property="AnnotationCanvas" Value="AboveChart"/>
</Style>

So as you can see its pretty straight forward, but this is where is gets weird, this functionality works perfectly on computers on which Visual Studio is installed on, but on other computers, the text annotation is selectable and moveable, but no amount of double clicking enables the annotation for editing. I tried forcing the textbox IsEnabled=”True”, but to no avail.

Any suggestions?

Thanks in advance

Basically i have two data sets (Y1,X) and (Y2,X) i will like to display them one over the other like in the attached picture. Also when i add cursor to one of them it should move the cursor on the other graph as well. Also the zoom on one of the graph should reflect the same way on the other graph.

Right now i am doing this with two sci chart surface, (no cursor linkage). which examples should i look at for this?

Hi,
I would like to be able to mimic the MouseWheelZoomModifier behavior programatically.

I have a slider control that I would like to zoom into the map. The same as the mouse wheel delta changes. I have a chart that has multiple Yaxis bound to the YAxes property of the SciChartSurface.

The mousewheezoommodifier works correctly, I just don’t know how to access the same functionality.

Thanks,

I am trying to create a custom CursorModifier Tooltip. It works in that it shows both of my lines on the screen and all the data associated with the lines. But what I would like to do is only report information about the first line, as the second line is only there for visual purposes as default. Here is a sample of my code.

<ItemsControl Margin="6" ItemsSource="{Binding SeriesData.SeriesInfo}">
 <ItemsControl.ItemTemplate>
  <DataTemplate>
    <StackPanel Orientation="Vertical">
     <StackPanel Orientation ="Horizontal">
      <TextBlock Style="{StaticResource HintDataItemsStyle}" Text="Available Imports:"></TextBlock>      <TextBlock Style="{StaticResource HintDataItemsStyle}" Text="{Binding Value, StringFormat=\{0:###\,##0\}}" />
       </StackPanel>
      </StackPanel>
     </DataTemplate>
    </ItemsControl.ItemTemplate>
   </ItemsControl>

What I’ve tried to do is change the ItemsSource to SeriesData.SeriesInfo[0] which seems to get only the line I want, but then the Value bindings below no longer work.

Hi All,

Can I add YAxis as DateTimeAxis and XAxis as NumericAxis?

Thanks,
Arthur

Hi,

Is possible in SciChart to plot just points in the chart, with no line connecting the points?

Hi,

I’m trying to set the text format for a date time axis without success, the labels always show time only like hh:mm, no matter what is the textformat string or the zoom level.
Tried with “dd-MMM-yyy hh:mm”, “dd-MMM”, “g”.

Appreciate you help on this.
Thanks

Hi,

in a MVVM scenario, I bind the AnimatedVisibleRange to a property in the view model.

 <s:SciChartSurface SeriesSource="{Binding ChartSeries}">
   <s:SciChartSurface.XAxis>
     <s:NumericAxis AxisTitle="x" AnimatedVisibleRange="{Binding XVisibleRange, Mode=TwoWay}" AutoRange="Never" />
   </s:SciChartSurface.XAxis>
   <s:SciChartSurface.YAxis>
     <s:NumericAxis AxisTitle="y" AnimatedVisibleRange="{Binding YVisibleRange, Mode=TwoWay}" AutoRange="Never" />
   </s:SciChartSurface.YAxis>
   <s:SciChartSurface.ChartModifier>
     <s:ModifierGroup>
       <s:MouseWheelZoomModifier IsEnabled="True" XyDirection="XDirection"/>
     </s:ModifierGroup>
   </s:SciChartSurface.ChartModifier>
 </s:SciChartSurface>

Setting the XVisibleRange property in the view model smoothly animates the view. However, when I zoom in the chart with the mouse wheel, the view model property receives no updates (so the XVisibleRange property in the view model always stays on the value initially set by the view model).

The same thing works when I bind he VisibleRange instead of the AnimatedVisibleRange, i.e. in that case I get an update of the view model property on every mouse wheel zoom.

Is this intendend, or a bug? Building a workaround would require additional bindings, which I would like to avoid.

Best regards,

Andree

Hello!

Is there any method to paint FastBandRenderableSeries using some image like template? (see the picture below)

Thanks in advance

Hi All,
i did the Zoom X with this code:
private void ZoomExtentsX_Checked(object sender, RoutedEventArgs e)
{
if (rubberBandZoomModifier != null)
{
var checkBox = (CheckBox)sender;
rubberBandZoomModifier.IsXAxisOnly = checkBox.IsChecked == true;
}
}
also i make the code for Zoomping in Y Axis by this code :
private void ZoomExtentsY_Checked(object sender, RoutedEventArgs e)
{
if (rubberBandZoomModifier != null)
{
var checkBox = (CheckBox)sender;
rubberBandZoomModifier.ZoomExtentsY = checkBox.IsChecked == true;
}
}
the zoomX run good but for the Y Axis it’s not ok because the code zoom x and y in the same time (like picture) !! anybody have idea ? Thank you !

I’d like to be able to hide the line in the FastLineRenderableSeries so only the markers show. I’ve tried setting the width to 0, but that throws exceptions as it can’t handle 0. Currently, I am setting the brush to Transparent so it is invisible, but I suspect there is still some processing related to drawing going on.

Is it possible to allow a width of 0, which just skips the drawing logic completely for the line and move on to markers?

I have some text items which are bound to the “DataValue” members of CursorModifier’s “AxisInfo”. These work just fine most of the time. But after enabling and then disabling a particular mode in my program which involves a customized version of RubberbandXyZoomModifier, the X-axis data in AxisInfo no longer responds to my cursor position. Curiously, the Y-axis data continues to work fine.

I’m still using SciChart version 2.3 (I haven’t upgraded to 3.x yet). Is there a chance what I’m seeing is a bug in SciChart? I can’t find anything in my code which could cause this behavior, at least not yet…

Thanks,
–George

For some reason SciChart cannot render two VerticalLineAnnotation bound to to the viewmodel.

I have the following xaml

    <sciChart:SciChartSurface.Annotations>
                            <sciChart:VerticalLineAnnotation VerticalAlignment="Stretch" FontSize="12" FontWeight="Bold" ShowLabel="True" Stroke="Orange" StrokeThickness="2" X1="{Binding Data.Region.Right}"/>
                            <sciChart:VerticalLineAnnotation VerticalAlignment="Stretch"  FontSize="12" FontWeight="Bold" ShowLabel="True" Stroke="Orange" StrokeThickness="2" X1="{Binding Data.Region.Left}"/>
                        </sciChart:SciChartSurface.Annotations>

When I place hardcoded values it works. And the first of the vertical line annotation always gets rendered correctly. Seems like a bug to me.

Hello.
I am using a FastLineRenderableSeries with XAxis as TimeSpan and YAxis as double values, updating at a very fast rate.
My question is what is the proper way to add another series as the envelope detection of the FastLineRenderableSeries.
Any suggestions or tips would be appreciated. Thank you.

Hi,
I’d rather have one tooltips for all my series like a legend.
But I want this special legend to be placed on the first (main) series tooltip coordinates.

I understand using a rollover is the best way to do it.

Hi guys,

Related with my previous question: how do I add the anottation lines to the chart legend? It seems it only gives me options about the data series, nothing else…

Thanks

I’ve been asked to design a UI that will act rather like some image viewers that you see on the web these days – we want to display a list of small chart “thumbnails” (with horizontal scrolling), and when one is clicked have it display at a larger size. Worst case scenario I see there being a dozen charts, each with varying complexity (a single series with a few points, up to several series/hundreds of points and maybe a couple of custom modifiers too).

These charts will be generated each time the user clicks on a cell in a datagrid (elsewhere in the window), so performance may or may not be an issue (although it could of course be done on a background thread).

Should I just be able to render and add all these charts to the ItemsControl (or whatever I use for the scrolling) or will performance suffer having many charts on screen at once? Would there be any benefit to rendering the charts to bitmaps, and using these as the thumbnails (I guess there would be more overhead in doing this)? I suspect the answer may be “try it and see”, but wanted to run it by you first.

Thanks in advance
Andy

I am showing tooltip with CursorModifier. My tooltip bigger than SciChartSurface and I am using ClipModifierSurface=”False” in order to show whole tooltip. But in this case axis labels and scroll bar are on top of tooltip.
Described problem can be seen on Featured Apps > Scientific Charts > Oscilloscope Demo.
Is there any way to bring tooltip on top of chart surface?

Thanks

My MVVM application can display more than 300 FastLineRenderableSeries on a SciChartSurface. SciChart handles the data and redisplays quite well. Thank you!

My users may mouse click on a series and quickly see the SelectedSeriesStyle change. The application needs to access the SeriesName of the SelectedSeries in the ViewModel for updates to other items in the ViewModel.

I read the topic/posts tagged SelectionSeriesModifier MVVM and the SeriesSource API. My attempts to utilize the CollectionChanged event of SelectedRenderableSeries (not in code-behind) have not had any success. It seems that I should do a OneWayToSource binding from SelectedRenderableSeries to an ObservableCollection<IChartSeriesViewModel> in the ViewModel. I would then like to use an MVVM Light EventToCommand bound to the CollectionChanged event.

Can you provide a demo or workaround on how to actually make this work?

Could you please post GridLinesPanelStyle from BlackSteel theme? I’ve overriden the style to remove border, and now it has default background, which isn’t in line with other elements.

Hi i am new to SCiChart and i was wondering if there is an option to double click on screen and make it full screen or maybe some sort of un-dock it or open it in new window full screen?
Thx

Hello,

i have a chart with one x axis and many y axes. What i try to archive is to draw a vertical rectangle over the chart in a specific x-interval but over full Y.

I guess annotations are the solution, i got them working (at least i see them on the chart), but i have questions:

Is it possible to add an annotation without a corresponding Y-Axis? I do not want to connect them to a YAxis since it does not make sense in that case. They should always occupy the full Y range. And, what are the correct Y1 / Y2 values? I tried Double.NegativeInfinity/Double.PositiveInfinity and Double.MinValue/Double.MaxValue but both crashed.

Many thanks,
Robin

I’m not clear how you set up FIFO with the SciStockChart class and mvvm; docs are a little weak; all the examples seem to use datasets rather than ChartSeriesViewModel. Do I simply set the fifocapacity? Do I need to set it at instantiation? Do all the ChartSeriesViewModels in a collection need to have the same Fifocapacity? Can I change the fifocapacity at runtime; and if so how would I change the capacity of all of the ChartSeriesViewModels (assuming they must all be the same) in a collection?

thanks in advance.

Hi sciChart,
I create a custom annotation base type BoxAnnotation.

<s:BoxAnnotation x:Class="ChartComponent.Annotations.TowLines"

In the oil industry a well survey is usually displayed by a series of points connected by arcs. An arc is very close to the actual path a drill will take between points on a survey. Survey points are about 90 feet apart, so connecting them with a straight line looks ugly. Which method should I override to accomplish this?

If I get ambitious, I may also consider using Bezier curves to connect points, as this could be useful to represent geological boundaries as a background for my well survey plots.

I have attached a picture showing the type of plots I need to make. The red line is a survey and the background represents geological layers. The survey is presently connected with straight lines, which makes it difficult to determine precisely where the survey intercept the boundaries.

I have four basic line charts that are next to a storyboard animation. Basically when I press run, I draw a vertical line through each chart that moves based on the elapsed time of the animation. The point is to show where in the time-axis the current animation frame is occurring.

I was using Windows.Controls.DataVisualization.Tookit but when drawing the four lines my animation would become choppy. I tried implementing with SciChart and find the performance is just as bad. Any tips? It was my understanding this would be a great improvement.

My approach is just to have two FastLineRenderableSeries per chart, and every time the animation traps in the Storyboard_CurrentTimeInvalidated, I clear the 2nd series(that only has 2 datapoints) and do a series.append at the coordinates of the line. If I disable the lines, it runs fine, and if I switch tabs on my application so the charts are hidden(but lines are still being drawn), it runs fine.

Thanks.

I am working on an application where I have multiple XY data series. For one of the series, we are producing annotation data for some of the points. There are 8 different types of annotations that can be created. Based on the response you gave to a previous question, I am creating the annotations as separate data series instead of as actual annotation objects since there are thousands of them. Performance starts to suffer as the number of annotations increases.

The issue I’m running into now is the number of series is now 14 which is unwieldy for displaying in a legend. My current legend is horizontally oriented as shown in the attached image. I would prefer that the user not have to scroll to view all of the legend items and am trying to figure out how to achieve that.

Is there a way to specify a fixed width for the legend and have items wrap to a new line if there is not enough room for them? I didn’t see that as being an option for the standard legend template.

Also, is there a way to use multiple legends for a chart? Ideally it would be nice to split the series that are associated with annotation data into their own legend instead of mixing them in with the legend for the normal data. The SeriesInfo object doesn’t appear to have any property that would allow me to categorize the data.

Thanks,
Scott
