I was able to develop and run everything using the scichart alpha build from Jun 11th.
This includes SciChart2D, SciChart3D, with a minor error.
I was using .NET Core 3.0 Preview 6+, Visual Studio 16.3 Preview on a Win7 box.

However, the client wants to upgrade to Windows 10.
So I installed Visual Studio 16.3 (2019), and .NET Core 3.0 and I was able to build all the packages etc.

However, when launching the WPF part of the application, I was at first encountering AccessViolation exceptions in CreateRenderTarget().

I removed all my SharpDX components, and tried again. I was able to get around this problem by using a version of SciChart 6.0 greater than the Jun 11th alpha version – v. 6.0.0.12382-alpha.

I can now load SciChart2D package.

However, SciChart3D is now throwing null reference exceptions when loading. I’ve included the screenshot. This occurs even with the 6.0.0-beta version.

Please advise.

Hello Team,

We are going through the Trial version of Sci Chart and we are specifically interested in 2D Scatter Chart and Simple Scatter Chart 3D.

For 2D Chart we tried to bind up-to 1 Million data points and it worked perfectly and we can zoom in 2D Scatter Chart to view each and every point.

When we tried the same for Simple Scatter Chart 3D, it was competitively slower than 2D Chart.

can we do the same in Simple Scatter Chart 3D?

Currently the whole chart is zooming in. Is there a way so that user can zoom in (XAxis , YAxis ,ZAxis ) individually so that each and every point in the chart can be View-able ?

Thanks,

Hello.

I have previously asked a question regarding Android and Xamarin (https://www.scichart.com/questions/android/legend-outside-of-chart-area).

Now, I have the same question, but for iOS. Do you have any examples available for taking chart legend outside of chart area on iOS?

Thank you and have a nice day!

Regards,
Paul.

ICoordinateCalculator calculator = this.SciChart.XAxis.GetCurrentCoordinateCalculator();

During the first run, the xAxis and calculator both are not null nor empty, but only the calculator.size is 0. Only after the second run the size has value. Why is this happening? Or is there any alternative way to get the calculator.size?

I would like to create custom annotation combined with multiple annotations like attached picture.(Text + box + line * 3)

Are there any good solutions?

Now I am creating it with separate each annotations showed code below. In this way, it is difficlt to move or delete them with group.

        <s:SciChartSurface.Annotations>
            <s:TextAnnotation Foreground="Black" 
                              HorizontalAnchorPoint="Center"
                              VerticalAnchorPoint="Bottom"
                              Text="XXX um" 
                              X1="90" 
                              Y1="6" />
            <s:BoxAnnotation X1="84" X2="96" Y1="2" Y2="11" Background="#77FFFFFF" />

            <s:LineAnnotation Stroke="Black" X1="85" X2="95" Y1="3" Y2="3"/>
            <s:LineAnnotation Stroke="Black" X1="85" X2="85" Y1="6" Y2="3"/>
            <s:LineAnnotation Stroke="Black" X1="95" X2="95" Y1="6" Y2="3"/>
        </s:SciChartSurface.Annotations> 

And one more question.

How to catch the event of adding annotation of view side from viewmodel?

Thank you.

hello

I have two questions,

First , when I using :

   sciChart.ExportToFile(SaveFileName, Core.ExportType.Jpeg, false,savingImageSize);  

In ContoursView ,this function works well, however in UniformMesh3DChart and SurfaceMeshContours it dosent work.
Only these parameters can be used:

    sciChart.ExportToFile(SaveFileName, Core.ExportType.Jpeg, false);  

as these parameters they dont work either:

    sciChart.ExportToFile(SaveFileName, Core.ExportType.Jpeg, true);  

Second, As “ExporToFile()” function, Can I export to file with ColorMap in UniformMesh3DChart and SurfaceMeshContours ?

In many of our applications we will have a number of flags that need to get plotted with data, these are usually each just represented by a single bit in a 32 bit integer.

Would it be possible to write a custom render-able series that plots a trace for each bit, or alternately would it be possible to point multiple custom renderable series at an XyDataSeries and have each of them plot a single bit.

I have started to have a look into this but am not sure how much of the re-sampling process happens before draw, and if this would make this a pointless exercise.

In addition, how much performance is lost by creating custom renderable series (vs using a number of the FastLineRenderableSeries on a dx surface)

Hello!

I am trying to render a HeatMap and align labels next to squares (see the attached image). However, I am running into two issues.

Firstly, I am using RenderTransform to shift labels so that they are aligned with the squares instead of being on the borders between them. It works, but does not look good as I resize the control.

Second, the axes render the last label outside the view. I tried setting VisualRange and VisualRangeLimit but it did not help. It hides the last data column (or row) and still displays the last label.

Any suggestions on how I can solve it?

I am attaching a sample project.

Thank you in advance!

I need to know if the user is dragging the entire line annotation or just dragging one end.
If the user is dragging the entire line, I see this cursor:
enter image description here

If the user is dragging just one end, I see the hand cursor:

How can I detect this from the code behind?

I have looked at all of the properties and commands.

Hi!

I would like to plot a series as a solid line AND include error bars. The way I do this now is to define a single series:

var fSeries    = new HlcDataSeries<double, double>();
fSeries.SeriesName = $"My Series!";

And then two different ViewModels:

var fLineVm = new LineRenderableSeriesViewModel();
var fErrorVm = new ErrorBarsRenderableSeriesViewModel();

And set the data series to belong to both:

fLineVm.DataSeries = fSeries;
fErrorVm.DataSeries = fSeries;

This looks ok. But when I show the legend, I see “My Series” in the legend twice, and I can control the error bars separately from the line series.

What I want to happen is that I see the series a single time in the legend and if I turn it off (uncheck it) everything disappears.

Right now, i’m adding those two ViewModels to an ObservableCollection of IRenderableSeriesViewModels and then SeriesBinding to display them.

I am doing all of my integration with SciChart using c# code.
Is there a way to simply customize the text of the Rollover modifier?

By default it shows

“`
x: somevalue
y: somevalue
z: somevalue

“`

when a data point is selected. I would like to simply change it to

“`

Time: somevalue
Profit: somevalue

“`
Is there a way to do this in pure c# without having to define xml templates etc?

Hi,

I am using VerticalLineAnnotation to point to a specific value of XAxis. I want to move this annotation by binding this X1 property and the SelectedX property of ViewModel. But even if SelectedX property was changed, the location of this annotation was not changed immediately. It was changed only after operating the chart (Zooming, etc).
Please let me know any solution to move an annotation immediately.

Hello.

I am working on Xamarin Android project with C#. Since having a legend within the chart causes problems with too many axis’ (no scrolling is available thus selecting different series in a legend becomes unavailable) and having a legend outside of chart area, anywhere we desire, would be of a preference, is there a tutorial on how could I achieve such a thing? Our project needs this functionality for both Android and iOS.

Would be grateful if anyone could help out with this issue.

Thank you in advance!

I recently needed to change the Rotation Angle of a polar plot from the default to 90 degrees. We have line annotations for different points on the polar plot. After the change, the annotation was still plotted on the default Rotation Angle.

I manually updated the points like this for the annotations to work:

var line = new LineAnnotation();

                var x1 = (double)NewSeries.DataSeries.XValues[0];
                var x2 = (double)NewSeries.DataSeries.XValues[1];

                if (x1.Between(0, 90) && x2.Between(0, 90))
                {
                    x1 += 270;
                    x2 += 270;
                }
                else
                {
                    x1 -= 90;
                    x2 -= 90;
                }

                line.X1 = x1;
                line.X2 = x2;

Is there another way to update the annotation or is something like this the preferred way?

When putting a chart into a listbox, the listbox doesn’t detect if the chart is clicked.

How can i change this, or there is any workarround to it? because i need it to select the parent ListBoxItem.

The problem is that when you put an event listener on the chart it doesn’t know where it is in the list, and when you put it in the listbox it doesn’t see it at all.

Thanks.

PS: I attached an example project where this happens.

Hi!

I have a chart that display time-series data and sometimes I have a few minutes of data, other times I have hours. All of the data points are taken every minutes. The X-Axis starts at 0 minutes and progresses from there.

My goal is to have the Axis Title say “Minutes” if there are < 120 points of data. If there are > 120 points of data then I want the Axis to be titled “Hours” and then divide the X-Axis label by 60.

I’ve started with this: https://www.scichart.com/documentation/v5.x/webframe.html#Axis%20Labels%20-%20LabelProvider%20API.html

and it’s doing about what I expect. I check the AxisCore’s Range and if the range is > 120 I set the AxisCore.AxisTitle to “Hours”, otherwise “Minutes”. So far so good.

The problem is that doing it this way means I have labels such as “48.333333” for the hours.

If, on the other hand, when I create the XYSeries that I’m plotting I pass in the already-divided-by-60 values, SciChart seems to select whole numbers so instead of showing me something like “48.333333” it would either show me “48” or it would use 50 or another whole number for the tick marks.

So my question: Is this doable by just writing a custom LabelProvider? Do I need to write a custom Axis class instead? Or somehow tell the Axis that’s in-use to recalibrate itself by dividing all of the elements by 60 before computing tick marks?

In the images I’m attaching, one plot shows me plotting a series where when I create series the x-value is being divided by 60 before I call .Append() on the series. The other one shows what happens when I use my custom LabelProvider and divide by 60 when the Axis label is drawn.

Thanks!

I am still experiencing the effects of this defect despite using v2.5.0.2598 of the Android libraries. Can someone please explain to me how to circumvent this behavior? It seems silly to require a base series that is ultimately going to be replaced by real-time updates.

I’m trying to control the size of the bubbles that are being plotted in the FastBubbleRenderableSeries.

I’ve tried all these things, but I can’t seem to figure it out:

  1. Changing values that are plotted: there seems to be some “normalization” that occurs behind-the-scenes, so whether I scale the raw values, the bubble size is identical.
  2. Changing ZScaleFactor: Regardless of what value I use for ZScaleFactor, the bubble size is still the same.

I’ve attached the problem I’m facing, would appreciate your help.

Thanks.

Hello,

I have the problem, that sometimes only one label is shown on the X-Axis even when there is space to show some more, than only one.
The property “IsLabelCullingEnabled” would show them all, but than it is ugly if there is not enough space.
So what can I do to have some more Labels shown?

In the Screenshots you can see that with only a few pixels more, more labels are shown, but the could have been also shown with less pixels (Especially Label “1” and “22” could have been shown).

To whom this may concern:

I would like to create a custom data series where I can manipulate the X-Values more efficiently for a ColumnRenderableSeries, where if I remove a column from the chart or there is a gap in the data, I won’t have any spaces between any of the columns in the chart. I also haven’t found any documentation on creating a custom data series.

My approach is to treat the X values like a stack.
– If a point is appended, a value is pushed to the X values stack and the Y values list.
– If a point is to be removed using RemoveAt(), it only removes the Y-Axis value from the index and pops the X values stack so the order and spacing of the x-values remain the same.

This is similar to Microsoft Excel, where removing a data row linked to a chart deletes the X-axis value instead of leaving a gap.

My thinking is making the following derivation of XYDataSeries (in C# pseudocode):

ColumnDataSeries<TY> : XyDataSeries<int, TY> where TY : IComparable
{
    Stack<IComparable> XValues { get; set; }
    IList<IComparable> YValues { get; set; }

    Append (T value) 
    {
        XValues.Push (XMax + 1);
        YValues.Add (value);
    }

    RemoveAt (int index) 
    {
        XValues.Pop ();
        YValues.RemoveAt (index);
    }
}

Can you please advise or provide any documentation for this?

Thank you, and best regards!

Hello

I have 2 charts, a 2D Heatmap and a 3D Waterfall chart, and I want to be able to programmatically change their color palettes.

The 2D heatmap is set up like this, with the GradientStops bound to an ObservableCollection:

...
<s:HeatmapColorPalette x:Key="HeatmapColorPalette" Maximum="{Binding MaxValue,Mode=TwoWay}"  GradientStops="{Binding ColorPalette}"/>
...
<s:SciChartSurface.RenderableSeries>
    <s:FastUniformHeatmapRenderableSeries 
        x:Name="heatmapSeries" 
        DataSeries="{Binding Data}"
        ColorMap="{StaticResource HeatmapColorPalette}">
    </s:FastUniformHeatmapRenderableSeries>
 </s:SciChartSurface.RenderableSeries>
...

This works as expected. When the binding changes the palette/heatmap changes.

The 3D waterfall is set up the similarly:

...
<s3D:GradientColorPalette x:Key="GradientColorPalette" IsStepped="False"  GradientStops="{Binding ColorPalette}" />
...
<s3D:SciChart3DSurface.RenderableSeries>
    <s3D:WaterfallRenderableSeries3D
        x:Name="waterfallSeries"
        DataSeries="{Binding Data3D}"
        YColorMapping="{StaticResource GradientColorPalette}"
        SliceThickness="1">
    </s3D:WaterfallRenderableSeries3D>
</s3D:SciChart3DSurface.RenderableSeries>
...

This, when passed the same data, doesn’t render the chart.
This chart otherwise works fine if I define the GradientStops statically in the XAML.

This is the GradientStops definition (in f#):

let BlueRed = 
        new ObservableCollection<GradientStop>([
            new GradientStop(Color.FromRgb(0x00uy,0x00uy,0xFFuy),0.0)
            new GradientStop(Color.FromRgb(0xFFuy,0x00uy,0x00uy),1.0)
        ])

I am not sure what I am missing.

(edit: apologies for formatting issues in the question)

I just switched from using the CategoryDatetimeAxis to the DatetimeAxis. I need to use the DatetimeAxis because i first fetch datetime data that has an interval on a minute basis. After that the data will be in a one second interval. The CategoryDatetimeAxis results in a equidistant behaviour which does not reflect the usecase in this scenario. The distance of the values must be relative to their difference in time. That is why the DatetimeAxis fits my need.

However, the DatetimeAxis interpolates between two dates when there is no data available. Is there a way to disable this behaviour, such that no line is drawn between two dates, but just a gap. I have tried to use the DrawNaNAs = LineDrawMode.Gaps, but this only works on nan data. Which is not precisely the case.

I have attached a picture which reflects my point. The red circled area is what i don’t want to show. Ideally the two dates would just squash next to each other.

I have a fairly simple multiple series line chart, which shows the history of a couple of variables within the last 5, 15, or 30 minutes.

The x axis is always ranged between Now – X mins and Now + 10 secs (to allow for clock error).

I’d like to have the x axis constantly scrolling, smoothly. I’ve not been able to achieve this using a timer. I’ve tried to use AnimatedVisibleRange, triggered from a 500ms timer, but there’s quite visible jerking.

I should add that the data comes in sporadically, but the chart should still scroll without any new data.

What am I missing? Thanks

Hi!

I’ve put a couple of charts in a recyclerview based on this example. I’m using a custome theme that’s basically just a white background and grey gridlines. When the charts get recycled (after scrolling them out of view and then back) they start to look weird. Does anyone know what is causing this behavior? I’ve tried two different versions of SciChart, screenshots attached below. Additionally I used to only get some random black squares like this in version 2.0.0.1654, but I can’t seem to reproduce that now.

Chart normally:

I have created a CustomControl that have scichart surface which draws a FastLineRenderableSeries and some other controls like buttons etc for controlling how data is displayed.
I have some dependecy properties like
– VisibleRange
– Horizontal and vertical Anotations values
as well as the XyDataSeries<double,double>

When I use the control in a window I can data bind to a viewmodel and VisibleRange and the annotations are fine but not the update of the XyDataSeries.

Any ideas?
