Hi!
I am going through the showcase example for the spectrogram and I had a confusion on the sizeX and Y parameter of SCIUniformHeatmapDataSeries. Are these sizes as per the width and height of the surfaceChart ? I am going to plot an array of data. How do I determine the correct sizes for X and Y.
Moreover, is it necessary that the size array used for updating the dataSeries has to be (xSize*ySize)?

I have a custom label formatter which only takes int and covert to string. But for Histogram I need to plot X values with double values. So i cant use that Custom label formatter.

I have created a default axis style for 2d chart(below), I find if I want to binding the “Stroke” property in MajorTickLineStyle, it will report
“Cannot find source for binding with reference ‘RelativeSource FindAncestor, AncestorType=’scichartWrapper.TwoDSciChart’, AncestorLevel=’1”. BindingExpression:Path=MajorTickColor; DataItem=null; target element is ‘Line’ (Name=”); target property is ‘Stroke’ (type ‘Brush’)”. But the “AxisBandsFill” binding can work.Does MajorTickLineStyle support binding Line’s Stroke property?

Hello,

We are working on developing an application that will be deployed on tug boats.
Our end users have asked that we provide a “night mode” to help reduce glare at night as it gets very dark out on the open water and any light reflected off windows seems incredibly bright.

Has anyone previously asked for a simple black and red “night mode” graph theme? If not, would it be possible to put one together?

Thanks,

Aaron

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.

Could I have a date please.

is it possible for the December or more likely for January?

Hi, currently in my application, when mouse over the data point, the line will be selected. If mouse over the line, the line will not be selected. Is there any way to know that the line is mouse over and make the line selected?

Hi,

I was following https://www.scichart.com/example/android-chart-custom-series-spline-line/ to implement a custom bezel curve. This works fine for static datasets but when I append values to the datasets they are not getting reflected (i.e has no effect on realtime datasets). Is there something that I am missing?

Thank you for your support.

This time, I’d like to know
– how to get the position data on cursor in the heatmap.
– how to draw or remove the horizontal and vertical line on cursor point in the heatmap.

Thank you.

Hello,

I’d like to have some kind of highlight functionality for a chart as shown in the attached image. Actually it’s exactly what a ScrollBar control does for an overview, but without changing the visible range. Is there any way to (ab)use the ScrollBar for functionality like this? If not, can you perhaps give me some pointers on how you would implement something like this. Or if there is something similar in SciChart I missed?

When displaying a value in a stacked column chart, if the value is negative, the negative value should be drawn from the 0 position of the y-axis or from below the other negative value if it exists. Similarly, the positive value after the negative should be drawn from the 0 position of the y-axis or from above the other positive value if it exists. But instead, in both cases, they are being drawn from the end of the previous value, resulting in overlapping.

I use SciChart.5.4.0.12119.

Some lines on the image are missing(picture1).
But, if zoomed image, the lines is drawn(picture2).

I want to show all lines wighout zooming.

Is there any way to solve this problem?

Hello,
Can someone explain how to set SeriesValueModifier.IsSeriesValueModifierEnabled for particular RenderableSeries in code?

Hi guys,

I have some troubles with piecharts in swift. I want to provide custom labels outside of the piecharts segments. I found a screenshot of a nested piechart attached to an issue in your issue tracker. Thats what I want to do in swift, but I couldn’t find out a way to do so. Could you please provide an example code?

Thanks a lot in advance!

My chart is dynamic, adding data from the right side all the time, and scrolling the chart to the left. Now the chart can manually scroll to the right indefinitely, but there are many blank areas on the right side. What can I do to limit the range of scrolling to the right? Is there any way to limit the zoom ratio to prohibit the chart from scrolling to the right indefinitely?

Hello,

in the attached solution i tried to extend the chart in your MVVM-Tutorial an overview control as it is shown here: https://www.scichart.com/example/wpf-chart-example-scroll-chart-using-overview-control/
However i get multiple binding exceptions that i not really understand.

I would be very thankful if you could help me out.

Best regards

Hi, I want to rotate an ObjectModel3D with multiple axis of rotation.
But Rotation property of ObjectModel3D can set only one axis (X or Y or Z).
How can I solve this problem?
Thanks

Hi.
I’m in process optimizing my app.
I’m using Objective-c.

I’d found some memory leaking issues and successfully fixed some of that.

A first issue was about ‘renderableSeries’ under ‘SCIChartSurfaceView’.
If you set class of UIView as ‘SCIChartSurfaceView’ in interface builder and make outlet without setting ‘strong’ or ‘weak’ in .m file,
It never get released automatically and will stay retained on memory.
For me, it caused about 90MB of memory leaking.
But I could solve this issue manually by putting -(void)clear; method of renderableSeries in viewWillDisappear method.

Another issue is about ‘SCIDateTimeDeltaCalculator’ and ‘SCINumericDeltaCalculator’.
It causes about 50MB of memory leaking.
But problem is, I couldn’t find neither where it’s been called nor how I release this manually.

I will be waiting for your answer.

Thanks.

Hello,

I have a WPF .Net 6 application running on Window 11 that monitors data coming from the network.
The app has five tab controls, each tab has four FIFO line charts.
I have another app (the “sender”) that sends simulated data to feed and test the “main” app.
Everything works beautifully when:
– The sender app is not running
– then, first navigate through all tabs, seeing an empty chart (expected)
– Launch the sender app.
– Navigate through tabs, watching them updating in near real time…

But…
If I do not initially navigate through all tabs, only the visible tab gets updated.

I suspect/speculate that SciChart code is doing some “critical” initializations on the OnLoaded event that are missed if tabs do not get loaded before setup.

We want the charts to get populated even if they are hidden at startup.

Any suggestions to fix the issue? Or am I doing anything wrong ?

Thank you

Basically i have two data sets (Y1,X) and (Y2,X) i will like to display them one over the other like in the attached picture. Also when i add cursor to one of them it should move the cursor on the other graph as well. Also the zoom on one of the graph should reflect the same way on the other graph.

Right now i am doing this with two sci chart surface, (no cursor linkage). which examples should i look at for this?

Is there a way to update the entire data series instead of a particular y value at an index ?

https://www.scichart.com/documentation/js/current/typedoc/classes/xydataseries.html#update

i currently place my custom (templated) legend inside the Scichartsurface (via xaml).

How can I offer the feature to drag the legend with the mouse to any location on the surface? Please note that I also use mouse movements and clicks for several chart modifiers so most likely I would have to check whether the mouse is hovering over the legend when a left mouse click event is raised?

Could you please get me started with some ideas or thoughts as I am not sure how to approach this issue.

Thanks

As I see in the chart surface you have VerticalSliceModifier. Why you don’t have HorizontalSliceModifier? It will be useful (for me))))

The tick labels of a MATLAB log-scale plot can display as “10^X “.
https://www.mathworks.com/help/matlab/ref/loglog.html

But the log-scale axis in the examples has a style like “Num X 10 ^X”. Is it a way to customize these labels to remove “Num X” before “10^X”?

Furthermore, how to set which value could display a label? I just want the label with integer superscripts. For example, if the VisibleRange = (0.01,1000), only the following tick values :0.01,0.1,1,10,100,1000 can display an label.

PS.
If cannot remove the prefixed “Num X” easily, is it possible to make the labels show the value not using scientific numbers? (display 0.01,0.1,1,10,100,1000 directly)

Hi,

I’m using the error bars series, and I get some strange behavior when zooming in/out using the RubberBandXyZoomModifier.
Sometimes the vertical line is not drawn, and sometimes the top & bottom horizontal lines are not drawn / drawn too wide.

This issue doesn’t occur when zoom with the MouseWheelZoomModifier.
However, with the MouseWheelZoomModifier in the current implementation the top & bottom horizontal line width depend on the zoom level (the zoom level affects the horizontal lines), where in my opinion it should not. For example, when zooming in, the horizontal lines may cover the whole view width, and when zooming out to a certain level you cannot see them since they are too short.

I attached a few screenshots of the same data in different zoom/pan, when using the RubberBandXyZoomModifier (the MouseWheelZoomModifier issue can be easily reproduced with simple data).
Screenshot ‘error_bars_display1’: horizontal lines are too wide.
Screenshot ‘error_bars_display2’: vertical & horizontal lines are not drawn at all (left line. Only the scatter series cross marker can be seen).
Screenshot ‘error_bars_display3’: vertical line is drawn, but horizontal lines are not (left line. This is one mouse wheel rotation-click away from screenshot #2).
It seems like an issue with the line size calculations (?).

Note: the ‘closing’ value of the HlcSeries is drawn using a Scatter series with a cross marker, so you can ignore it in the attached screenshots.

Thanks.

Hi,

I created a chart legend based on the online example. I have three data series: an XyScatterRenderableSeries, a FastColumnRenderableSeries, and a FastLineRenderableSeries. The plot itself is fine. But the legend isn’t. In addition to the checkboxes bug (I don’t need these and so have set ShowVisibilityCheckboxes=False, to no effect), I’m seeing color samples for the scatter and column data, but nothing for the line. All three series names appear as expected, but I’m missing the color sample for the line plot. What’s up?

Thanks,
–George

Hi!

I have the following code for a vertical slice modifier

    <s:VerticalSliceModifier Name="sliceModifier"
                                             ReceiveHandledEvents="True"
                                             >
                        <s:VerticalSliceModifier.VerticalLines>
                            <s:VerticalLineAnnotation Style="{StaticResource sliceStyle}"
                                                      X1="{Binding ParentViewModel.SliceModifierPosition, Mode=TwoWay}" />
                        </s:VerticalSliceModifier.VerticalLines>

 </s:VerticalSliceModifier>

This results in a nullreference exception. When I remove the VerticalLines, there is no nullreference exception, also no vertical lines.
As far as I can see ParentViewModel.SliceModifierPosition, does not have a value at the time.

I tried setting the visibility of the slicemodifier to collapsed, but it did not help the exception. Is there any to remove the slicemodifier for the time when X1 is not valid (using MVVM and not binding the slicemodifier itself)?

Hello,

I’m working at displaying a map using FastNonUniformHeatmapRenderableSeries. I want to make it looks blurry, so there will be smooth transition between inner edges.

How can I do it?

Thanks in advance

Hi every one,
In order to pan and zoom the graph (from the example https://www.scichart.com/wpf-chart-example-pan-on-mouse-drag/ ), I used MouseWheelZoomModifier for zooming and ZoomPanModifier for panning.
The code is as below:

                <s:ZoomPanModifier x:Name="zoomPanModifier"
                                   ClipModeX="ClipAtExtents"
                                   ExecuteOn="MouseLeftButton"

However, when I zoom out the graph and pan it horizontally, the graph auto stretch (auto zooming). That is not what I expected, I want disable this feature but I have no idea how to do it.

Hello,
we have a problem while executing our unit tests on our jenkins server.
The unit tests are run via the Nunit Console Runner.
In one specific Test project the unit test aborts with a “SocketException”.
The output looks like this:

Test Files D:\dev\jenkins\workspace\c\build\test....\source\Exec64_Release\Test.dll
Writing out DLLs to C:\Users\user\AppData\Local\SciChart\Dependencies\v8.1.0.27856\x64
System.Net.Sockets.SocketException : No connection could be made because the target machine actively refused it 127.0.0.1:65018

So because there is the line with “Writing out Dlls ….” which contains SciChart and the next line is the SocketException I just wanted to ask if there is something in SciChart which tries to connect to the localhost, I don’t know e.g. the licensing?
I don’t want to blame SciChart, I just want to ask if it could be possible. Because it is not easy to debug this scenario reliantly.

Best Regards,
Nick
