ZoomPanModifier provides Pan+Zoom functionality. But, is there modifier for Pan only?

I don’t want to zoom the chart when edges are reached during panning.

How can I implement to my CustomChartModifer(like custom RollOverModifier) a Storyboard:
The Storyboard shall change the Visibility(or Opacity) of my RollOverModifer to Visible (MousePosition changed), wait 5 s and change back to Hidden?

Hi, SciChart team.

In FormattedText class constructor textAlignment parameter is used only for calculating measurement, it does not apply to any TextBlock.

Is it bug or feature?

Hello

I have requirement do change majorDelta/autoTicks for different ranges
for example:
If the max is <= 10,000, MaxAutoTicks should be 5
If the 10,000 < max < 20,000, MaxAutoTicks should be 4

what is the best way to achieve this taking into account user zooming and adding data in the background?

Hello,

I am evaluating SciChart and have been very impressed so far with the power and ease of use.

I have a need to plot a single series Mountain style chart with 64K data points and then update around 10 times a second. The X values are fixed, the Y values may vary from update to update.

Is there a way to prevent redraws while I am updating the data in the series (planning on using a loop calling dataSeries.Update(TX, TY) for each point unless you can suggest a better way)

Thanks and Kind Regards

Hi folks,

In order to test something, I decided to load the sample Abt.Controls.SciChart.Core.Wpf.Example which installs with SciChart. When I try to run it, I get the following VS2012 error. I did a reinstall (or rather, a “repair” install), but nothing changed.

Error 1 The command “pushd “C:\Program Files (x86)\ABT Software Services Ltd\SciChart v2.1.1\Examples\Abt.Controls.SciChart.Wpf.Example\Examples”

Hello,
The SciChartOverview is great, it provides exactly the functionality that I needed for panning and zooming. The only problem is that from what I have found until now it works only on the x axis.

Is there an easy way to have exactly the same zooming and panning functionality provided by the SciChartOverview on the Y Axes? I just need the zooming and panning, not the data preview.

I tried to do this by modifying the ControlTemplate of the NumericAxis control, but I quickly got into trouble, and this seems like a little bit too much work anyway.

Is there a simple way to do it with SciChart?
I added an image with a similar control that does this.

I have a scichart surface and i plot the chart after that i add max and min limits line to the chart surface.but i can’t able to view the limits line untill i double click the chart surface (Zoom Extents Modifier is used).how can i refresh the chart surface when the y axis scale value changed.In my limits function i call chartsurface.zoomextents but i will not helped.

Hi

I would like to use a converter for my chart ohlc data,
So a bar that is appended with some set of values, should be displayed in a factor of 10.
for example:
open price of 15.41 would be displayed -> 154.1
is it possible?
thanks.

In FastLineRenderableSeries, when I draw lines that go backwards, zoom functionality does not work properly. When I zoom-in graph is not visible.
You can try with following x,y values
{x=2010, y=0.15} {x=100, y=0.15} {x=100, y=-0.15} {x=2010, y=-0.15} {x=2010, y=0.15}

HI,
I’m new in scichart. I would like to ask you if it’s possible to build a graph with custom candles.
I want to build a footprint graph, something like this:

http://footprintchart.com/wp-content/uploads/2011/06/Shade_Dominant_Side.png

could you tell me if It’s possible to build this kind of graph and suggest me some links with documentation?

Thank you

Hi~ supporter

On testing scichart for a migration of our chart library, I had a some problems.

Because I tested scichart for just two days so It maybe my mistakes..^^

1. MouseWheelZoomModifier does not work.

– If There is no series on chart area, MouseWheellZoom works well but After add curve, It stop working.

1. Rubber Band Zoom for Stacked bar chart

– After adding serveral stacked bar charts, When I try to do rubber band zoom for stacked bar chart, Stacked bar often disappear.

1. ZoomExtants for Stacked bar chart

– After adding several stacked bar charts, When I call “ZoomExtants()”, all stacked bar charts does not fit in chart area.

I attached a sample program.
I will looking forward to your answer.

Regards,
Sunchul

Hi,

I’ve got several line chart series in my ChartSurface and it’s possible to collapse and show them dynamically. If I collapse all series and only one series visible I would like to see that one in the OverView chart. But I cannot find a way to get it done. DataSeriesIndex always get the first series in the parentSurface regardless of it’s visibility. Is there any way to show the first visible Series in the Overview chart?

<chart:SciChartOverview ParentSurface=".." DataSeriesIndex=”1″ SelectedRange=”{Binding ElementName=.., Path=XAxis.VisibleRange, Mode=TwoWay}”>

Charith

I constantly have OutOfMemoryException when I set IChartSeriesViewModel.DataSeries.FifoCapacity and there are 4 or more chart on a single SciChartSurface.
Exception’s code block is

viewModel.DataSeries.FifoCapacity = 1000000;

where viewModel is newly created instance of ChartSeriesViewModel class.
What it could be?

Exception stack trace is

A.  `1..ctor(Int32  )
Abt.Controls.SciChart.Model.DataSeries.XyDataSeries`2.ClearColumns()
Abt.Controls.SciChart.Model.DataSeries.DataSeries`2.Clear()
Abt.Controls.SciChart.Model.DataSeries.DataSeries`2.set_FifoCapacity(Nullable`1 value)

p.s. I have no opportunity to set x64 as target platform. My SciChart version is 3.1 but there is the same problem with 3.22.

I am binding to the Rollover Data Series Info and displaying the YValue in a grid. I want to also display the XValue, however when I bind using XValue nothing is returned. It only seems to display data for the Value property and the seriesname property

Hi,

Quick question regarding stock charts. I am maintaining the Ohlc data series and appending values when the timeframe threshold is reached.. what the BarTimeFrame property is used for in StockChart?

Thanks

I am using SciChart for WPF version 1.3.1.1107 with the MVVM pattern.

I have several lines in one chart where the data from for each line covers the same date time range. I’d like to be able to move a line to the front so that I can better see its data. Currently the order in which I add the lines seems to impact the zindex of the lines series.

Is this possible?

Hi all,
I developed my application in real time where i introduce my WPF in winforms
So i developed the class Graph.xaml.cs where i defined my function :
public void CreateDataSetAndSeries(List lstX, List lstY)
{
series0 = new XyDataSeries<DateTime, double>();
using (this.sciChartSurface.SuspendUpdates())
{
series0.Append(lstX, lstY);
}
lineSeries.DataSeries = series0;
sciChartSurface.ZoomExtentsY();
}

i don’t make the code of charting in the constructor also not in the function sciChartSurface_Loaded() because i must filling those list from the winforms frame after this i make the code for zooming in the Graph.xaml :

<SciChart:SciChartSurface.ChartModifier>

<SciChart:RubberBandXyZoomModifier/>

                <SciChart:ZoomPanModifier ExecuteOn="MouseRightButton"/>
                    <SciChart:ZoomExtentsModifier ExecuteOn="MouseDoubleClick"/>

                <SciChart:CursorModifier ReceiveHandledEvents="True" ShowAxisLabels="True"  ShowTooltip="True" ShowTooltipOn="MouseRightButtonDown"/>

But the problem i have the two cursor (like the picture) but i can’t did the zoom pan (also i put stop for my application to make a Zoom but i have the same problem ) !! i am blocked in this step someone can help me it’s urgent ! and Thank you !

Hi, is it possible to use html or other kind of formatting on a NumericAxis.AxisTitle? I would like to have text in different colors and bold/normal options. Thanks.

Hello all,

I want to add a vertical line at a specific date:

VerticalLineAnnotation newVerticalLine = new VerticalLineAnnotation();
newVerticalLine.X1 = ((DateTime)pAnnotationAttributes.GetValue(GUI_AnnotationAttributes.TimeValue)).;

Doing this I get the following exception:

Hi there

I have written a stock chart application. As part of that I have a drop down box that allows the selection of the bar timeframe (e.g. 1m , 5m, … 1r, 4h etc). It all works fine. However, if I bring up a chart and then do some zooming and panning AND THEN select a new timeframe, sometimes the data is not initially visible and I have to scroll the chart to find it ! Should I be resetting the visible range in some way?

Thanks

Paul

Hi everyone,

i’m just looking for a polar chart that can plot 3D-Data like Heatmap Chart. Anyone has an idea about it?

Hi all,
I want to capture the XY coordinate related to XY axis of my scichartsurface after a MouseLeftButtonDown. At first I try this:
Point mousePoint = e.GetPosition(((SciChartSurface)sender));
but the coordinates are in pixel? instead I want my xy that are double…

Then I try this code from an example:

Point mousePoint = e.GetPosition(((SciChartSurface)sender).GridLinesPanel as UIElement);
var hitTest = ((SciChartSurface)sender).RenderableSeries[0].HitTest(mousePoint);

now hitTest.XValue and hitTest.YValue are the correct data of the nearest point, but I want the exactly coordinates of the point where I clicked, not the nearest. It is possible? How can I do?
Thanks for reply

I am trying to use SciChartGroupPane and ChildPanes for my application, and
want to collapse a pane , so that the remaining space is filled with the remaining graphs.

I tried binding the Visibility property to the charts itemcontainer style, but it only partially helped.
I got all the panes collapsing except for the first one. I attached a sample project, where I try to collapse all panes but the last one.

I asked the question here
https://www.scichart.com/questions/question/collapse-pane-in-grouppane-charts
but got no answer since then. The project could probably not be uploaded beacuse of the size.
I uploaded it here:
https://drive.google.com/file/d/0B19IHNOVxrKCYlUzQjRnOF9ZRnc/view?usp=sharing

Is this behaviour normal? Is it a bug? Please help.

Hello,

it would be fantastic to be able to select the series visualized in the overview control. If i understood correctly, it’s always the first serie that is shown currently.

I added a screenshot, where 2 overviews are used. Both are based on the same first series (Curve 1). To be able to select another curve for overview 2 would be awesome.

Thank’s a lot!

Robin

Hi!

I am trying out a feature in my application with editable vertical lines annotations. My problem is that my set method needs to perform some calculations when the vertical line is moved, and since the set method is being called multiple times when moving the annotation, it slows it down and doesn’t give the user that great feeling that it should

Is there any way of delaying the set method being called until the user actually drops the annotation?

i have the data values as shown below.

But the negative values are not plotted when XAxis is set to AutoRange? Does the dataset need to be ordered for the graph to render properly? How do I set the range to display negative values. I am using FastLinerenderable series.

How do i copy two Scicharts placed vertically on grid in a application.
By now i can copy at a time single SciChart.
Attached is a runtime window where i need to copy both SciCharts with single right click on copy.
Currently i am using 3.1Version.

I have an application that has a MainWindow that launches new ChartWindows (contains SciChart code) when you click a button. Each ChartWindow is launched on a new thread to avoid UI freezes. Also each one of the windows has a background thread that received live data from the exchange and updates the chart. Everything was working fine on version 1.7, but then I decided to update version 2.1.1 this week and that’s when the issues started.

After I open my first ChartWindow and try opening a new one I get a XmalParseException (see attached picture and exception.txt file). The only changed I made besided replacing the .dll file was updating the way DataSeries are created on the v2.

I am attaching the .cs and .xaml file for my ChartWindow, and this is the code I use to launch those windows:

    private void ButtonBase_OnClick(object sender, RoutedEventArgs e)
    {
        Thread thread = new Thread(() =>
        {
            ChartWindow w = new ChartWindow();
            w.Show();

            w.Closed += (sender2, e2) =>
             w.Dispatcher.InvokeShutdown();

            Dispatcher.Run();
        });

        thread.SetApartmentState(ApartmentState.STA);
        thread.Start();
    }

Besides that code, there is nothing else in the MainWindow.xaml.cs.

As I said before this was working fine on v1.7 (the code for v1.7 is still there but commented).

I appreciate any help I can get, thanks.
