I would like to dynamically add and remove columns from a ColumnRenderableSeriesViewModel in code behind.

I am using MVVM and the SeriesBinding. I assigned a XyDataSeries<double, double> to the ColumnRenderableSeriesViewModel .DataSeries.

The chart initially draws all the bars for each item in the XYDataSeries, but If I append or remove one of them, the chart does not update and show the new bar or remove the old bar.

Here is my XAML:

        <s:SciChartSurface RenderableSeries="{s:SeriesBinding RenderableSeries}">
            <s:SciChartSurface.XAxis>
                <s:NumericAxis />
            </s:SciChartSurface.XAxis>

            <s:SciChartSurface.YAxis>
                <s:NumericAxis />
            </s:SciChartSurface.YAxis>
        </s:SciChartSurface>

And some of my view model:

using SciChart.Charting.Model.ChartSeries;
using SciChart.Charting.Model.DataSeries;
using System.Collections.ObjectModel;

namespace ChartExample {
    public class ChartViewModel {
        ColumnRenderableSeriesViewModel _seriesViewModel = new ColumnRenderableSeriesViewModel();
        XyDataSeries<double, double> _dataSeries = new XyDataSeries<double, double>();

        public ChartViewModel() {
            RenderableSeries.Add(_seriesViewModel);
            _seriesViewModel.DataSeries = _dataSeries;
        }


        public ObservableCollection<IRenderableSeriesViewModel> RenderableSeries { get; } = new ObservableCollection<IRenderableSeriesViewModel>();


        public void AddSeries() {
            _dataSeries.Append(_dataSeries.Count, _dataSeries.Count);
        }


        public void RemoveSeries(int seriesIndex) {
            _dataSeries.RemoveAt(seriesIndex);
        }
    }
}

Can you please tell me what I might be doing wrong?

I have a situation where I need to have a lot of independent realtime charts rendered on the screen at the same time. I have put a scichart into a user control and that user control into a list so I can reuse my configuration.

Unfortunately, the behavior I am seeing is that when I have more than 5 charts, the charts stutter really badly. I’m using the SciChartPerformanceOverlay to determine what the FPS is of each of the charts.

I can see that in my 5 chart situation, if my mouse cursor is NOT over the window or NOT moving on the window, each chart has an FPS of ~18 for SciChartSurface and an FPS of >500 for Composition Target. When I start to move the mouse around on top of the window, the SciChartSurface FPS value drops to < 5 and the Composition Target drops to ~300.

I’ve got no mouse events hooked up, I’ve set TryApplyDirectXRenderer to true and it seems to accept it. I’ve double-checked the following values:

Direct3D10CompatibilityHelper.HasDirectX10CapableGpu: True
Direct3D10CompatibilityHelper.HasDirectX10RuntimeInstalled: True
Direct3D10CompatibilityHelper.IsSupportedOperatingSystem: True
Direct3D10CompatibilityHelper.SupportsDirectX10: True

I’m suspending the chart before adding points. Each chart only has 1000 points inside a XyDataSeries<int, double> that is databound to a FastLineRenderableSeries. I’m even using Update instead of Append to try to reuse the same memory, in case that makes a difference.

I’ve played with the MaxFrameRate and nothing seems to help.

My dev machine is a bit old and the graphics card is Intel-based, but I never imagined the performance would get so bad so quickly. I’m hoping there’s something I’m missing here as I’ve read such good things about SciChart.

Please let me know if there’s any advice.

Thanks

I’m trying out polar chart for my specific needs. In my scenario x-axis needs to display 0-360 (angle) values starting from bottom and going counter-clockwise so that 0 is at the bottom, 90 is at right, 180 is at the top and so on. Looking at polar chart default x-axis display it starts from right and go clockwise. Is there any way to change this behavior?

Hi ,

I am currently using the DataPointSelectionModifier for StackedColumnRenderableSeriesViewModel and I am having an issue trying to have a single selection that is togglable.

I am currently not AllowingMultiSelection so the default value is SelectionMode.Replace, which, in case you click on the same column, it will deselect that column and then select it again. Is there a way around this?

Best Regards.

Hi There,

I work for a company where they use WPF SciChart alot in many applications.I am new bee to SciChart but I need to learn them in deep to meet our user requirements.So can you please let us know how can we get good command of sci charts.Are there any video tutorials? Are there any simple samples to start.

Regards,
Priya

I’ve been trying to get SciChart to work with good performance and as part of my experimentation am trying to see how RenderPriority.Manual works. As far as I can tell, it doesn’t.

I haven’t been able to find much in terms of samples or docs. According to the little documentation here:
https://www.scichart.com/documentation/v4.x/SciChart.Charting~SciChart.Charting.Visuals.RenderPriority.html

It says

Manual — Never redraws automatically. You must manually call
InvalidateElement() or ZoomExtents() on the SciChartSurface in order
to get it to redraw

Now, when I try to call either of those functions on my SciChartSurface, nothing visually happens. I’ve tried other Invalidate methods as well, and still no refresh love.

I’ve attached the small sample application that repro’s the issue.

Please let me know what I’m doing wrong.

Thanks,
Brian

Hi, I am currently working with the DataPointSelectionModifier with StackedColumnRenderableSeriesViewModel series. I currently am able to get the data point with the correct values whenever I click on a column but it seems that I am not able to change the selection fill of the column.

All I can seem able to do is changing the color of the whole series, but that is not what I am looking for.

Best Regards.

Hello, I am currently importing and displaying a .obj file as a ObjectModel3D object similar to the following syntax of the code provided in the AddObjectsToA3DChart.xaml example:

object:ObjectModel3D TextureSource=”{StaticResource BlackTexture}” Source=”{StaticResource KnightLowObj3DSource}” Position=”0.0625, 0.6, 0.8125″ CoordinateMode=”Relative” Scale=”0.2, 0.2, 0.2″ Rotation=”{StaticResource ObjRotationState}”

Where ObjRotationState is : object:Rotation3D x:Key=”ObjRotationState” Axis=”YAxis” Angle=”180″

The above code excerpt sets the rotation angle at 180 degrees on the Y-axis only for the ObjectModel3D object.

However, I would like to set the rotation angle for the X, Y, and Z axis of the ObjectModel3D object at the same time. Is it possible to set the rotational angle for multiple axis as described? If not, are there suggested workarounds to achieve the same behavior?

Thank you for your assistance.

After update to SciChart.6.2.1.13304 we get an InvalidOperationException:

Hi guys,

I’ve been trying to select data points in my heat map for the whole without success. I’ve read, re-read and re-re-read the documentation, but I can’t figure out what I’m doing wrong.

Here’s the XAML.

What am I missing?

Hello SciChart-Team,
I noticed that the columns in Sparse Column3D and in Uniform Column 3D always start at the XZ surface. Is there any option or way to do so, that columns always use the zero value of the Y axis as their starting point. The visible range of the axes should correspond to the minimum and maximum Y values.

The current behavior can be reproduced in the example SciChart_UniformColumn3D:
If the VisibleRange of the Y-axis goes from 0 to 0.5 then the columns with negative values go down (see screenshot 1)
As soon as the VisibleRange of the Y-axis goes from -0.5 to 0.5, the columns look like this (Screenshot2) We need the columns to look like in Screenshot 1, only that the Y-axis is also visible downwards.

Can the starting point of the columns be changed?

Best regards
Silvester

Is there any way Gantt Chart be plotted based on the dynamic data.
The example https://www.scichart.com/example/wpf-chart/wpf-chart-example-gantt-chart/ shows plotting Graph using predefined data loaded through constructor.
In the same example if a new item is added dynamically to the Item Collection in the View-Model it should reflect in the Graph.

Also how to plot the graph if a single project has multiple timeline.

How is it possible to sync SciChart with a ListView? The vertical chart grid should be the same width as the list view columns. A ScrollBar or a Chart-Overview should be used for synchronous scrolling of the X-axis and the ListView.

Hello SciChart team,

I wanted to implement 3DSelectionModifier that should select a point closest to the mouse pointer per mouse click.

To do this, I create a rectangle with a clicked point in the center with a mouse click and use the PickScene method of the ViewPort3D object.

List<EntityVertexId>? entityVertexIds = Viewport3D.PickScene(mousePoint.ToRectCenter(30));

Depending on the camera angle It can of course happen that several points appear in the scene. In this case I wanted to do the following:

for each determined point in 3D space, determine its 2D screen coordinates

HitTestInfo3D hitTestInfo = new HitTestInfo3D() { IsHit = true, EntityId = entityVertexId.EntityId, VertexId = entityVertexId.VertexId };
SeriesInfo3D? seriesInfo = pointsEntity.ToSeriesInfo(hitTestInfo);
//Vector3D hitVertex = seriesInfo.HitVertex; 
Vector3 vertex = seriesInfo.HitVertexCoords; 
Point point1 = ParentSurface.Camera.WorldToScreenSpace(vertex); 

Determine the distance between the point of the mouse and the 2D coordinates of the point from the scene

double newDistance = PointUtil.Distance(mousePoint, point1);

Select the point with the shortest distance.

if (distance.IsNaN() || newDistance < distance) 
{   
  distance = newDistance;   
  nearestSeriesInfo3D = seriesInfo; 
}

During the implementation I encountered the following problem:
I used following camera object method first

Point p = ParentSurface.Camera.WorldToScreenSpace(vertex);

but this gave me no plausible point.
The other method

Point p = ParentSurface.Camera.LocalCoordinateToScreenSpace(vertex);

also seemed to return a point that returned the wrong value when calculating the distance, so the wrong point was selected.

If I try to click the data point directly, I expect at least one of the methods to return a point very very close to the mouse pointer. However, both methods gave me a point on the screen (see screenshot) that did not match the mouse point.

Maybe I’m missing a step or transformation. Could you explain me what I’m doing wrong?

Hello

In Tutorial 06b – Realtime Updates, I want change the <s:SciChartSurface.XAxis> from <s:NumericAxis/> to <s:DateTimeAxis/> . I have tried a lot, but it still doesn’t work.

Could you please help me to do this work.

Thank you very much.

Hello,

Normally, if I have a ScichartSurface with a X- and Y-Axis, were both axis AutoRange- properties are set to Always, the surface displays the entire data by adjusting the Visible ranges of the axis after new data has been appended.

This also works if there are multiple Data-Series on the ScichartSurface.

In my case, I have two FastLineRenderableSeries on my Surface. Each of them receiving new data via the Append-function while the x- and y-axis are continuously adjusted automatically to display all the datapoints of both Datasets.

So far so good…

But what would I have to do if I wanted one of the two Datasets to be ignored by the Autorange properties of the x- and y-Axis?

I have already tried to set the X- and YAxisID of one dataset to null, hoping I could make both axis ignore this Dataset while they are adjusting their Visible ranges. However, this only led to error messages.

I could also try to write my own ViewPortManagers and overwrite the OnCalculateNewXRange and OnCalculateNewYRange funvtions, but that seems a little bit excessive.

Is there an easy way to achieve the desired behavior?

Thanks.

Hello,
I’m attempting to build one of the WPF examples on a machine that has no internet access. I get the error mentioned in the title. When I exported the project, I selected the “Installation Folder” option rather than the “NuGet Package”.

How can I fix this error?

Thanks, Brett S.

‘Hi i get a weird problem:

The type or namespace name ‘XyDataSeries’ could not be found (are you missing a using directive or an assembly )

I also get the error with IChartSeriesViewModel, FastLineRenderableSeries and IXyDataSeries

Hi

In terms of a oscilloscope for instance you can calculate what the time per division (time/div) is for the y-axis and the volts per division for the x-axis. This changes when you zoom in and out.

My question is how can I calculate these in the simplest way possible to calculate the volts per division according to the current zoom level?
You will obviously have inputs of the start frequency and amplitude when the application start or whenever these inputs changes on the units side.
But when you zoom in and out depending on whether you are zooming the y-axis or x-axis or both the time / div and volts / div needs to be calculated.

Thanks a lot Gert

Hi Scichart,

I am struggling with a ContextMenu on a SciChartSurface that wont be displayed.

The problem started when i added mouse panning with the right mouse-button which is the same button the ContextMenu is activated on.

So will this combination even work – with both a ContextMenu and mouse panning with the right mouse button?

To manually validate if the ContextMenu should open or if the panning should be enabled, I have tried to get the mouse coordinates manually in C# to see if the mouse was moved(panning) or if it was a click(ContextMenu). This did not work very well when i afterwards started to pan/zoom again.

Do you have a code example using both a ContextMenu and mouse panning using right mouse button?

Best regards,
Jeppe

Hello All,

i draw in real time my curve and i want added a line(For exemple Y=0.055) in my chart (like my picture)!
it’s possible to draw in Scichart a serie (line) when you make just the Yvalue like my picture i want just identify the Y=0,055 ?

how can i did this with scichart ?
Thank You

hi,
Guys i have a requirement to make a chart name volume by price please see the attachment image.
can we make this kind of charts .
Thanks in advance.

I’m trying to create a chart where the visible range is scrolling “window” that advances ahead of the most recent data point when the data hits the edge so that the line is always moving from the center of the chart towards the edge.

Say we have data coming in once a second, we want the window to be 60 seconds wide and advance in increments of 30 seconds. In SciChart terms, we would begin with a data range of 0-0 and a visible range of 0-60. The line will start at the left edge of the chart and, as points come in, advance towards the right edge. When we get a point at t=60, we will programmatically advance the visible range by our increment so that we have a data range of 0-60 and a visible range of 30-90. The line will now be advancing from the middle of the chart to the right edge. When we hit t=90, we will advance the visible range again so data range = 0-90, visible range = 60-120. Again the line will advance from the center of the chart to the edge. And so on.

My current problem is the scrollbar. If I have a data range of 0-90 and a visible range of 60-120, the total extent of the chart as far as a normal viewer is concerned is 0-120. The scrollbar should reflect that, and the bit of the scrollbar that indicates the visible section should take up half its total width (0-60 being in the past and 60-120 being visible). Instead, the scrollbar is sized as though 0-60 is in the past and 60-90 is visible. Touching the scrollbar at all will, in fact, set the visible range to 60-90, re-rendering the chart and eliminating our buffer of visible space to the right. My question is how do I fix this behavior so that the scrollbar is aware of the “real” range of the chart which is neither data range nor visible range but a combination of the two?

I am considering applying server-side licensing for my javerScript application.

In the document below, there is a phrase “Our server-side licensing component is written in C++.”
(https://support-dev.scichart.com/index.php?/Knowledgebase/Article/View/17256/42/)

However, there is only asp.net sample code on the provided github.
(https://github.com/ABTSoftware/SciChart.JS.Examples/tree/master/Sandbox/demo-dotnet-server-licensing)

I wonder if there is a sample code implemented in C++ for server-side licensing.

Can you provide c++ sample code?
Also, are there any examples to run on Ubuntu?

Dear all, I am trying to export a heat map that I have generated that you can see at the right side of the attached image. However, the resulting XPS generated is the figure at the left. As one can see they are not very similar as one would expect. I have checked my code, but can’t seem to find the problem. Parts of my code are shown here to give more info. If anyone has tips why this strange result may occur , let me know please.

I have created a 3D surface mesh successfully and now I want to plot a data series on the mesh. The inputs to the data series are 2D (X,Y) with the Z axis value always being directly on the mapped 3D surface point at the specified X,Y position.

I am trying to populate a XyzDataSeries3D() collection like so…

var xyzData = new XyzDataSeries3D();
xyzData.Append(x, y, z);

How to I determine the Z value given I have the X and Y values? Is there a built-in method for determining this or do I need to do it myself?

Thanks.

Hello dear SciChart team,

Our customer has a new security program that starts on Dlls that are copied into a directory during runtime. At the moment has the customer the problem that this security program starts on an AbtLicensingNative.dll. This DLL is in the following directory:
% USERPROFILE% \ AppData \ Local \ SciChart \ Dependencies \ v.6.2.1.13304 \ x64.

For this reason the following questions:
Is this DLL safe?
Why is the dll only copied at runtime? Is there another solution for this?

best regards
Silvester
