I have noticed in official demos as well that when using DataPointSelectionModifier with drag select the last index point wont get selected. This is really annoying as the click functionality works but only drag for last index does not

Hello SciChart Team,

I would like to report an issue regarding WebGL1 support in SciChart v5+.

I am aware that WebGL1 support was removed starting from v5, and that the engine now requires WebGL2.
However, in my environment this is a hard limitation, and WebGL1 is still required due to legacy hardware and GPU constraints.

I performed multiple tests and can confirm the following:

SciChart v3 works correctly using WebGL1

SciChart v5+ does not render or fails to initialize on the same machine

The browser reports that WebGL2 is not available, only WebGL1

The same chart logic and dataset work perfectly in v3, but fail in v5+

This confirms that the issue is not related to the chart configuration, data, or memory usage — the only difference is the WebGL backend requirement.

Unfortunately, in my case, upgrading the hardware or enabling WebGL2 is not possible at the moment, so WebGL1 compatibility is still necessary.

I would like to ask:

Is there any official or experimental fallback to WebGL1 in v5+?

Is there any internal flag, build option, or legacy bundle that still supports WebGL1?

If not, is there any recommended migration path for environments that do not support WebGL2?

Thank you very much for your attention and support.

Best regards,
Júlio Soares

Hello,

I have a wpf application that has several SciChartSurface, each of which has a DateTime axis for the x-axis.
I am currently using MVVM to bind data to the axes.

I want to display a custom band on the x-axis but am having difficulty. depending on the data there could be one or more bands to display.

For example if the date range is from 2/3/2026-2/4/2026, there may be a band that needs to be shown from 2/3 10:00-11:00 and one from 2/3 14:00-14:25.

Can you point me to any examples that may show how to accomplish this?

Regards.

Many years ago, SciChart tech support provided me with code for a RollerMarkerHelper class. I implemented this in VB.net, but I’ve attached a C# version which I just created using an automated translator. This code takes as arguments a RenderableSeries and a style template. I used this, along with a very simple style template such as the one shown below, so that I could display a gray circle over whatever point the cursor was over. (This is useful in my particular application.)

But I’m implementing a new application in C# using the MVVM approach (e.g., LineRenderableSeriesViewModel). How can I modify the RollerMarkerHelper class to handle this, or is there another approach I should use?

    <ControlTemplate x:Key="SpectrumRolloverMarkerTemplate">
        <Ellipse Width="7" Height="7" Fill="SlateGray" Stroke="SlateGray" StrokeThickness="1" />
    </ControlTemplate>

Hi,
I’m working on a feature for wpf application where there will be multiple tab controls and each tab control can be able to plot the graphs . So I have a usercontrol with scichartsurface which is bound to dataseries of type LineRenderableSeriesViewModel. User should be able to close all the tabs one by one. But when we are closing the last tab the application is getting crashed with no logs being caught at wpf level unhandled exception. But getting the below message while debugging, for –
Exception {“Attempted to read or write protected memory. This is often an indication that other memory is corrupt.”} System.AccessViolationException

The usage of the scichart is as follows:

this scichartsurface is being placed inside an usercontrol and the user control is used as template to document page for docking manager control

Package used for scichart:
SciChart3D-8.5.0.28148
SciChart.DirectX-8.5.0.28148

Any guidance on the correct disposal/teardown pattern for SciChart in a multi-tab scenario, or known workarounds for last-surface shutdown, would be greatly appreciated.

Hi folks,

I’m using MVVM and need to implement hit tests. I found this post from nine years ago, saying it’s not yet implemented:
https://www.scichart.com/questions/wpf/hit-testing-a-renderableseriesviewmodel

Surely you have a solution by now? What is it?

Thanks,

Hey,
I’m working on a feature where users can edit DataPoint position directly on a chart by dragging them with the mouse, and I would like to ask for guidance, best practices, or existing examples. I see one example for SciChart WPF but couldn’t apply that to JS because many things differ between WPF and JS.

Goal
Allow users to change the point positions of a LineSeries by dragging individual points on the chart.

Given
An FastLineRenderableSeries (XyDataSeries) with EllipsePointMarker.

When
The user clicks and holds the left mouse button on a point (EllipsePointMarker)

Then
The selected point changes its appearance (e.g., bordered or highlighted) and it is possible to move the point to change the position of it.

On Mouse Release
The point position is updated
Line and point styling return to their default state

Hi,

I upgraded scichart.js from 3.5.774 to 4.0.918, my chart now has a padding on the right side even though it was not there before.
I only added yAxis to the left side of the chart and not the right (please see attached image).

I’ve already set padding to 0:
sciChartSurface.padding = Thickness.fromString(‘0 0 0 0’)

If I want to get rid of the padding, I now have to change it to:
sciChartSurface.padding = Thickness.fromString(‘0 -11 0 0’)

The breaking changes page only mention padding change to the SciChartSubSurface, but I am not using that. https://www.scichart.com/documentation/js/v4/whats-new/breaking-changes-v3-v4/

I only have one sciChartSurface.
const { sciChartSurface, wasmContext } = await SciChartSurface.create(divElementId)

Please let me know what might be causing this, thanks.

I’m attempting to create a custom CursorModifier to display series information aggregated across multiple SciChart surfaces into a single tooltip. These surfaces are synced via the VerticalChartGroupId with the charts displayed as part of an ItemsControl using MVVM. The default behavior only shows information for the series in the subpane where the mouse is. This makes sense given the CursorModifier is local to the subpane and set via a DataTemplate assigned to the ItemsControl.ItemTemplate.

To create a “global” CursorModifier, I’m guessing I need to override the GetSeriesInfoAt method of CursorModifier. I have access to all the IRenderableSeriesViewModels across all the subpanes via the parent view model. My question is how can I access the appropriate SeriesInfo object for each of these renderable series in order to return an enumerable of SeriesInfo objects? These should be the appropriate derived type (e.g. OhlcSeriesInfo, BandSeriesInfo, etc.) so that my template selector can do its thing. Thank you!

Hi folks,

In the old days, text annotations were implemented using a CustomAnnotationsChartModifier which would bind to a collection of TextAnnotationViewModels. The TextAnnotationViewModel included tool tip text in addition to the main text and the coordinates.

In the current SciChart, eventualy we now bind a collection of IAnnotationViewModels to the SciChartSurface’s built-in Annotations property. But these viewmodels do not implement a member for tool tip text.

How can I replicate my old code, which dynamically created and displayed text annotations which implement a ToolTip as well?

Hi folks,

I have this code in an old app:

                            <s:CursorModifier x:Name="MainCursor" ShowAxisLabels="True" ShowTooltip="False"
                                            ReceiveHandledEvents="True" LineOverlayStyle="{x:Null}">
                            <s:CursorModifier.AxisLabelTemplate>
                                <!-- This empty template hides Themes cursor labels -->
                                <ControlTemplate TargetType="s:TemplatableControl" />
                            </s:CursorModifier.AxisLabelTemplate>
                        </s:CursorModifier>

This used to work. But unfortunately, this produces the following error after upgrading (I’m not on WPF v8):
Property ‘AxisLabelTemplate’ does not support values of type ‘ControlTemplate’.

I need this feature because I want to display data from the CursorModifier in a corner of my plot, but not in the built-in axis labels. Setting ShowAxisLabels to False evidently prevents the data from being generated, so I need ShowAxisLabels to be True. The empty AxisLabelTemplate above worked to hide the axis labels, but not this code produces the error above. What can I do?

Hi,

When I create an ImpulseRenderableSeriesViewModel and set its PointMarker to null, the PointMarker still appears. I can hide markers by setting the PointMarker Width and Height to 0. But this seems like the wrong approach.

What am I missing?

Thanks,

I’m implementing a SciChart WPF (v8.6.30610) control that displays a single column within a SciChartSurface, which correctly stretches to fill the available width (≈800px). The chart is bound via MVVM using a ColumnRenderableSeriesViewModel and a UniformXyDataSeries(0, 1d) containing one data point. However, the column remains narrow (~50px) regardless of the chart’s actual width.

To investigate further, I modified the VisibleRange to (-1 ,1) and changed the data setup to UniformXyDataSeries(0, 20d). With this configuration, the column width increased slightly (to around 100px), but it still doesn’t scale proportionally to the SciChartSurface width. Adjusting properties like DataPointWidth or AutoRange has no effect on the column’s width.

My goal is for the single column to span the entire available chart width, effectively filling the space similar to a full-width bar.

Is DataPointWidth the correct property to control column width in this scenario?
Does the UniformXyDataSeries spacing or X-axis VisibleRange inherently restrict the rendered column size?
What is the recommended approach to achieve a full-width single column in SciChart?

Any guidance or clarification on the expected behavior would be greatly appreciated.

Attached is the working project (zip file) and also the image attached gives a clarity on the above ask.

Hi,

I’m trying to implement a selected BoxPlotDataPointmarker. What would be the best solution to do so?

Basically I have one series with multiple boxplot data points, which are colored by a custom pallete provider. Now I want to highlight selected data points. The idea was to change StrokeThickness. But I dont know how to do so for one specific data point of the series.

Hello Team,

I am using Sci 2D chart(version 8.9.0.28766) in c# .net WPF MVVM. I have 3 Fastline series with more than 16400 points changing every 2 sec with fixed x and y axis. I am following the SciChart_PointMarkersSelection example to use point markers.
Issue I am facing,

1. the point disappears as the data changes. I want the points to be persistent and moving with the new y values.
2. I want to add the fixed x values and changing y values of the selected points in a data grid
3. The user should be able to change the x values in the data grid and the point should move accordingly.
4. I want to get the data back to the observable collection in the View model.

The example is does not have realtime data changing every 2 min and the point marker x and y values are displayed on the UI as List.

Is this the right option to use PointMarkersSelection modifier? If not please suggest any alternative method to achieve the above goals.

I was thinking of putting the selected points in to a scatter chart and add it to the same IRenderableSeriesViewModel and update the corresponding y values as the new data comes in.
But my problem is, how should i get the nearest actual point in the data set and send it from UI to the view model to populated the scatter chat?

Hello

I am trying to introduce 3D chart to my application and render SurfaceMeshRenderableSeries3D.
The thing is that my dataset can get quite big, for UniformGridDataSeries3D yValues it can be dimension of
65 536 x 100. Because of WebGL size limitation I use data tilling and render multiple series that connect to each other. Similar how it is done in docs example for heat maps https://www.scichart.com/documentation/js/current/webframe.html#The-Uniform-Heatmap-Chart-Type.html

The chart renders, but when zooming/moving the performance is pretty poor. FPS drops down to 8-10 making it hard to work with.
This is my current series params:

      const surfaceMeshSeries = new SurfaceMeshRenderableSeries3D(wasmContext!, {
        dataSeries: heatMapDataSeries,
        meshColorPalette: colorMap,
        minimum: min,
        maximum: max,
        cellHardnessFactor: 0,
        shininess: 0,
        lightingFactor: 0,
        highlight: 0,
        strokeThickness: 2.0,
        contourInterval: 2,
        contourOffset: 0,
        contourStrokeThickness: 2,
        drawSkirt: false,
        drawMeshAs: EDrawMeshAs.SOLID_MESH,
      });

Is there any option that might help my achieve better performance? It would be fine to disable as much as needed just to make it more optimized for large dataset.

I would really appreciate any help with that

Hi Team,
We’re exploring the use of SciChart for data visualization in our Angular application, primarily because of its superior performance.

We have a specific business requirement to create a stacked line chart. The design requires each stack to have its own Y-axis, while all stacks share a common X-axis. We’ve attached a design mockup of the chart we want to achieve.

Our main questions are:

Is this type of stacked chart with independent Y-axes feasible using the SciChart library?

If so, what’s the best approach to implement it?

We’re looking forward to your guidance on how to make this happen.

Thanks,
Viswanath.

I’m working on a charting program for financial markets, and trying to develop a drawing system that uses SciChartJS annotations.

The initial implementation allowed annotations to be “naturally” selected, but leaving them editable to be selected resulted in users accidentally ‘snagging’ one annotation while trying to draw another, or while trying to pan the chart. To get around this, we implemented a “right-click -> edit” function to activate an annotation for editing, that programmatically sets isEditable and isSelected to true. I understand that this is not advised, but I’m not familiar with another way to exert the necessary control/restraint over annotations. (we DO let them de-select “naturally” and that seems to work)

This has worked with LineAnnotation and HorizontalLineAnnotation with no issues. But when implementing BoxAnnotations, we found that, while the annotation looks to be in “selected” state, the adorners don’t “fully open”. I can click them inside the box and drag to re-size, but if I click them on the box border or outside the box, they don’t respond and the box de-selects.

The adorners DO fully open if I click the annotation anywhere, or if I drag it or drag an adorner from the inside. After that, I can click anywhere on the adorner circle and drag properly.

Based on other posts in this forum, I’m assuming that this has to do with the AdornerLayer selection information not being set by a programmatic “isSelected = true”. Can you provide sample code for how to set an annotation as selected at the AdornerLayer?

(I asked an LLM to try to interpret this prior post https://www.scichart.com/questions/js/programmatically-select-customannotation and generate code, but I’m not sure it’s implementing the AdornerLayer change properly)

Thank you!

Good day,

I could use some assistance in properly handling legend selections between chart updates. What I want is to maintain user legend selection through DataSeries changes. See images.

You can see originally we have a StackedColumnRenderableSeries chart with component-based breakdowns on the x-axis. In the “WaterFiltered” image, we see that the bars containing water are hidden; however, when I update the underlying dataseries, the legend is reset and water bars are seen again. I do not desire this behavior. The water should remain unchecked. If the legend changes it is fine to allow the whole thing reset, but in this case I am only changing the underlying data series. Could you suggest some techniques to achieve my desired idea?

Here is some additional xaml resources in order to help:

如何在unity里面·使用scichart，导入进去老是报错，一会什么事件注册不了，一会同名，unity版本2022，scichart版本最新

We need to make heatmaps of our data and don’t know the type of data variables until runtime. Because of this I am switching the axes like so in XAML:

…

The key is that I’m a custom LabelProvider class to convert any categorical values into the appropriate label for the axes. I would have liked to use a CategoryNumericAxis for both axes, but for some reason it seems you can’t so I’m using a NumericAxis.

All data values are coming in as 0, 1, 2,… for the categorical variables.

I am running into two issues with the axes. First is that the last category is cutoff prematurely and I’d like to align the labels with the center of the category not the left edge. These issues appear with the CategoryNumericAxis.

The second issue is that I’m having issues aligning both the values and controlling the number of what I guess are the tickmarks for the Y axis since it doesn’t know it is categorical data. Is there any (easy) way to handle the Y axis for categorical data?

Attached is an image of what the plots are looking like:

How do I draw a waterfall 3D chart with the Z-axis as the height instead of the Y-axis, similar to the waterfall chart in MATLAB?

I’m plotting the binding series using scatter points. When I mouse left-button down on a point, I want to get the X and Y values for that point. However, because my data is so large, it doesn’t show the correct result without zooming in. That’s my code.

private void sciChart_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
// Mouse pozisyonunu al
var mousePoint = e.GetPosition(sciChartSurface);

// SciChart eksenlerinden gelen double veri değerlerini al
double xValueDouble = xAxis.GetDataValue(mousePoint.X);
double yValueDouble = yAxis.GetDataValue(mousePoint.Y);

// Double veri değerlerini int'ye çevir
int xValueInt = (int)Math.Round(xValueDouble);
int yValueInt = (int)Math.Round(yValueDouble);

// Bilgiyi göster veya işleyin
Console.WriteLine($" X = {xValueInt}, Y = {yValueInt}");
}

Drag the area in the 3D point chart to select a point.

The current occurrences are as follows.
The point in the camera view direction is selected. However, if there is an overlapping point, the first point is selected, but the hidden point is not.

Is there any way to solve this?

Hello,

when data count exceeds the amount of pixels of the control normally the ResamplingMode should take care of displaying the expected results. Setting the Resampling mode to either of the following modes doesnt always show the green / yellow heatmapdata.

• MinMaxWithUnevenSpacing
• Max
• MinMax

Depending on resizing the window (and availability of pixels for the control either green, yellow, none or both lines are shown. Orange block is always shown, as it spans enough pixels not to require ResamplingMode to work.

I have not found any mode to be able to make sure that heatmapdata is shown.

Am i missing something?

I created a boxplot chart using a FastCandleStickRenderableSeries together with a FastErrorBarsRenderableSeries, both using the same OhlcDataSeries. The error bars use the high and low values to draw the whiskers, and the HlcDataSeries is used for the mean point.

However, I’m currently facing an issue where the boxplot chart is not displaying tooltips. How can I achieve tooltip behavior similar to Highcharts, using a CursorModifier?

I am looking to add several new features to our tool that uses SciChartJS – one was addressed yesterday with marker positioning. Today I have two more requests:
1. How to grow/shrink a marker based on the datapoint on the Y-axis (my X-axis is time). Example, say a trader wants to show orders placed by an algo over the time duration. The order has a price and quantity associated with it – like:
8:30:31 – Buy ESM5 – 10 lots
8:30:40 – Sell ESM5 – 1 lot
8:30:45 – Buy ESM5 – 100 lots
8:30:50 – Sell ESM5 – 50 lots
etc.
The trader wants to see these orders plotted on the chart – Y-axis being the Price, Size of Marker = dynamic based on order size (10 lots, 1 lot, 100 lots, 50 lots, etc).
The color of the marker would be based on Buy = Blue, Sell = Red.

1. Another requirement is to show/hide marker based on some condition. Examples:

– Show the marker when OrderSize > 25
– Hide the marker when OrdeSize < 10 and Price < 1% of inside market

I have attached a screenshot showing what my timeseries looks like for an instrument.

Looking forward to a yet another awesome solution!

Best Regards,
Sachin.

I have a feature request from my users to allow markers to be positioned in one of the following locations with respect to the datapoint:

• center
• top
• bottom
• left
• right

In the image below, the SciChart’s default marker position is “center”. On the right, I have drawn different positions that my users are requesting.

I am looking for any help/tips/etc.

Hi,
My WPF software uses XyDataSeries<DateTime, double> to plot real time data from our device. I ran the program days and days and always got this crush. It happened randomly. Sometimes it happened in a couple of hours after ran the program. Sometimes it happened after several days. The SciChart library that we use is v 8.0.****. The following is the message from Event viewer. I understand the error message is general, but hoping if anyone has any idea or direction.
