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.scichart.com/index.php?/Knowledgebase/Article/View/17256/42/)

However, there is only asp.net sample code on the provided github.

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?

Hello,

I am having a problem where I want to display the Rollover Modifier only when I click on the selected graph.
For example:
https://demo.scichart.com/javascript-chart-rollovermodifier-tooltips
If I select the Second Lines Series, I want to see the rollover only for that particular graph and not the first one and the third one.

I have tried using charts id’s as a reference to show only one tooltip but it just enables it for all the graphs.

Any help would be kindly appreciated.

HI,
I am using Scichart for drawing multiple line series on the same chart.
sciChart Image
video to make it more clear https://youtu.be/O0WiocmldXY , when we have many channels we face a performance issue due to that, and the update rate of the lines become much higher and the responsive of the UI becomes bad.

this kind of graph called segmented graph, what it does it cuts a small portion from other line chart, and draw the data that crosses a specified threshold that the user choose.

we want to draw, up to 100 lines at the same time. each line has 30,000 points.

we assume that the high number of data series causes bad performance.
what can we do, to increase performance? is there a different line series we can use?

We have a scalablecustomannotation and i have embedded a png in side the snnotation svg. currently when I zoom in on the svg it does interpolation/smoothening of the pixels by default. what would like to set is pixellated mode where there is no automatic smoothening.

Any ideas how to achieve that?

E.g. please see the video below, what you see on the right in the video is what I get from scichart. what I am trying to achieve is the effect in the left window

Our application requires registration between visible image and heatmap data. I am able to do this with ScalableAnnotations which registers the image beautifully and is able to scale with the heatmap as shown in the video below.

unfortunately this is exactly opposite of what we need. The issue we are facing is we need the visible image to be under the heatmap and not over the heatmap. In our use case the relevant data in the heatmap is visible and rest of the data is transparent and needs to be over the visible image to colocate where the cancer is.

How do we achieve this?

Hello,

I have created a custom “polygon geometry” based on the BaseSceneEntity class. Since it can be any shape, all non-closed shapes like a plane (in 3D space) are only lit from the side from which the normal vector of my triangles points. The other side is pitch black. Is there a way to illuminate both sides when I rotate the shape?

Hi There,

I have 2 FastColumnRenderableSeries, one of which has 4 points and the 2nd has 2 points in dataseries.
Please see the attached image.
Is there a way to make all the columns have the same width ?

Thanks in advance!

The first question: Where did the example go (link below)?
https://support.scichart.com/support/solutions/articles/101000513349-tutorial-custom-legend-with-color-picker-and-custom-point-markers
I want to do like what and time ago I saved link but now this page is deleted. I need it because it is good example for resolve my 2nd question I think.

And the second question: I have chart

    <s:SciChartSurface Grid.Row="0" Grid.Column="0" x:Name="SciChartSurface" Margin="5" Padding="5"
                       ChartTitle="{mainVM:Localization MainChartSciChartSurface}" RenderableSeries="{s:SeriesBinding RenderableSeries}" Annotations="{s:AnnotationsBinding Annotations}">
        <s:SciChartSurface.XAxis>
            <s:NumericAxis AxisTitle="{mainVM:Localization XNumericAxis}" VisibleRange="{Binding VisibleRangeXAxis, Mode=TwoWay}" />
        </s:SciChartSurface.XAxis>
        <s:SciChartSurface.YAxis>
            <s:NumericAxis GrowBy="0.1,0.1"
                           AxisTitle="{mainVM:Localization YNumericAxis}" VisibleRange="{Binding VisibleRangeYAxis, Mode=TwoWay}" AutoRange="{Binding IsStaticYAxis, Converter={StaticResource StaticAxisToSciChartAutoRangeConverter}}" />
        </s:SciChartSurface.YAxis>
        <s:SciChartSurface.ChartModifier>
            <s:ModifierGroup>
                <s:SeriesValueModifier />
                <s:CursorModifier IsEnabled="{Binding IsShowValuesCursor}" />
                <s:LegendModifier x:Name="SciChartLegendModifier" GetLegendDataFor="AllSeries" ShowLegend="False"
                                  SeriesData="{Binding SeriesData, Mode=TwoWay}" />
            </s:ModifierGroup>
        </s:SciChartSurface.ChartModifier>
    </s:SciChartSurface>

Legend of chart placed in another panel

    <s:SciChartLegend x:Name="SciChartLegendControl" s:ThemeManager.Theme="Chrome" Margin="5,5" ScrollViewer.HorizontalScrollBarVisibility="Auto" ScrollViewer.VerticalScrollBarVisibility="Auto"
                      LegendData="{Binding SeriesData, Mode=OneWay}" ShowVisibilityCheckboxes="True" />

SeriesData is

private ChartDataObject _seriesData;
public ChartDataObject SeriesData
{
    get => _seriesData;
    set => SetProperty(ref _seriesData, value, nameof(SeriesData));
}

I want to see chart values in additional fields near the chart. I made this

<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="Auto" />
    </Grid.ColumnDefinitions>
    <ListView Grid.Column="0" x:Name="ChartsListView" BorderBrush="Transparent" ItemContainerStyle="{StaticResource ListViewItemContainerDefaultStyle}"
              ItemsSource="{Binding SeriesData.SeriesInfo}">
        <ListView.ItemTemplate>
            <DataTemplate>
                <Grid>
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="*" />
                        <ColumnDefinition Width="Auto" />
                    </Grid.ColumnDefinitions>
                    <Label Grid.Column="0" Style="{StaticResource LabelDefaultStyle}"
                           Content="{Binding SeriesName}" Visibility="{Binding IsVisible, Converter={StaticResource BooleanToVisibilityConverter}}" />
                    <Label Grid.Column="1" Style="{StaticResource LabelIndicatorStyle}"
                           Content="{Binding YValue}" />
                </Grid>
            </DataTemplate>
        </ListView.ItemTemplate>
    </ListView>
</Grid>

All working correctly. But I want to bind Legend visibility checkboxes to my custom controls for values: when I uncheck chart checkbox control bound to this chart must becomes invisible. In code above I write

Visibility="{Binding IsVisible, Converter={StaticResource BooleanToVisibilityConverter}}"

but it not worked. How can I make it like I want?

And 3rd question: how can I guarantee the order of SeriesData lines? I have to be sure that charts in legend and custom controls ordered in the same ordering

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.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?

Hi，
When I created the FastBandRenderableSeries type, I encountered an aliasing problem. When I used AntiAliasing, it still didn’t work.
There is an example of used code:

List<double> xData = GetData("D:\\x.txt");
List<double> yData = GetData("D:\\y.txt");
List<double> y1Data = GetData("D:\\y1.txt");
XyyDataSeries<double, double> splineBanDataSeries = new XyyDataSeries<double, double>();
splineBanDataSeries.Append(xData, yData, y1Data);
var bandSeries = new FastBandRenderableSeries()
{
DataSeries = splineBanDataSeries,
//Name = id,
StrokeThickness = 1,
Fill = Colors.Transparent,
FillY1 = Colors.Transparent,
StrokeY1 = Colors.LightGray,
AntiAliasing = true,
StrokeDashArrayY1 = new double[] { 5, 1 }
};
sciChart.RenderableSeries.Add(bandSeries);
sciChart.ZoomExtents();
Is there any way to correct this error?
Thank you.

Hi,
I’ve got some questions to expand on this topic: https://www.scichart.com/questions/js/how-do-you-export-or-save-a-chart-as-an-image-in-js-library

1) Can you export areas of a chart that are not visible on the screen? I have a large line chart, like a seismograph, that is never fully displayed on the screen because it is too long.

2) Can you export from a chart that is not visible on the screen?

Thank you

Hi,
I know that when I use MouseWheelZoomModifier with my chart surface, the default behavior is:
1. On mouse wheel (No keyboard mod) – Zoom according to the “ActionType” propery, and direction according to the “XYDirection” property.
2. On mouse wheel + CTRL – X-Axis pan
3. On mouse wheel + Shift – Y-Axis pan

I want to achieve this behavior:
1. On mouse wheel (No keyboard mod) – Zoom according to the “ActionType” propery, and direction according to the “XYDirection” property.
2. On mouse wheel + CTRL – XY-Axis Zoom
3. On mouse wheel + Shift – Y-Axis Zoom

Any idea how to achieve this behavior?
Thanks, Ben.

I wanted to customized my box annotation further, for example, I wanted to give my box annotation some border radius, it seem like there is no way to do so currently.

I know that there is custom annotation like svg annotation, but those are svg, the reason Custom annotation doesn’t work for me is because they are not responsive to zooming since they are image/svg, unlike normal box annotation.

For example, for normal box annotation, I can give it x1 to x2 so that when I zoom in the chart, the box annotation expanded. But for Custom annotation, they only take one x point for placement, so I can not cover x1 to x2, it only going to stay on x1.

So, I wonder if there is currently a way I can add border radius to a box annotation, or is there a plan to do so in the future?

Let me know, thank you!

Hello SciChart Community,

I am currently working on a Windows Forms C# application where I need to visualize a 2D byte array (A[MxN]) on a 3D chart using SciChart. However, I’m facing some difficulties in achieving this task.

My goal is to display the contents of the byte array A on a 3D surface plot or another suitable 3D chart type provided by SciChart. Each byte value in the array represents some intensity or elevation value.

I have explored the documentation and examples provided by SciChart, but I couldn’t find specific guidance on how to achieve this.

Could you please provide some assistance or guidance on how I can achieve this visualization using SciChart in a Windows Forms C# application? Any code snippets, examples, or documentation references would be greatly appreciated.

Thank you in advance for your help.

Best regards,
Namblue73.
