I didn’t see anything in any docs, so I am just wanting to verify this info…
Is this correct that you have to link in and ship the libSwiftCore (+ other swift libs) with an app using SciCharts on iOS? When I added the chart library to my app; the app crashed at startup with missing dynamic load of libSwiftCore.dylib on a real device (emulators run fine).
Enabling ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES in the build settings fixed this issue. But this surprised me that the SciChart library would actually require Swift.
Was this intentional; or did the library somehow pickup an unintentional reference somewhere….
one more question.
Same example from your SDK – 2D charts, Column Chart
I.e. for X-line (Y = 0).
The rest X lines shall remain the same.
I could not find the SciChart API documentation for the release we use (3.4.2): neither in the installation files, nor on the SciChart site.
Is that documentation still available somewhere?
Is it possible to put a background image on a chart? I hope you can give me a hint thanks in advance.
I attach an image for the purpose of my query.
As you already know, I’ve implemented a wrapper of scichart.
In a clear Nuxt project, I can get the scichart.data / scichart.wasm files very well. Have no problems with that at all.
But on my current project, we can’t implement this because some dependency is missing from scichart. And without your code, I really don’t know how to get into it.
The image is on attachments. Can you help us?
I’m trying to implement sciChart to flutter app (Android). It gets pretty confusing when trying to make it work. Anyone have examples how to make SciChart to work on Flutter? Adding the license works just fine. Only need for ECG chart for now. Thanks.
At right chart we have show only one X-axis which needs to update in real time .whenever new values will come we have to update in X-axis in itself instead of adding new line at X-Axis.
Each time New Y – axis will come that will append at left chart (Can be consider left chart showing history of right chart)
Let me know if anything further requred
one more question please;
Please see the pict below (same SDK example: 2D charts-> Column Chart)
Just added the Legend and Rollover:
<s:SciChartSurface.ChartModifier> <s:ModifierGroup> <s:ModifierGroup> <s:LegendModifier x:Name="LegendModifier" ShowVisibilityCheckboxes="False" ShowLegend="True" Orientation="Vertical" Margin="10" HorizontalAlignment="Right" ShowSeriesMarkers="True" /> <s:RolloverModifier x:Name="RolloverModifier" ExecuteOn="MouseMove" ShowTooltipOn="MouseHover" IsEnabled="True" /> </s:ModifierGroup> </s:ModifierGroup> </s:SciChartSurface.ChartModifier>
I’d like to keep Series Name in one place – on Legend and remove it from Rollover tooltip text.
I.e. tooltip shall be “13.7” in this case.
I found how to format the Legend (LegendModifier.LegendItemTemplate SciChart WPF v5 SDK User Manual)
But didn’t find the similar way for Tooltip.
Could you please let me know how to achieve this?
I’m using auto range on a numeric axis. The data can be anything, but I want the axis to never have a range of less than 5.
E.g.: -100 to -95
E.g.: 17 to 22
E.g.: 0 to 5
What do I need to set to be able to do this? I have tried MinimalZoomConstrain and VisibleRangeLimit without success. Preferably something to set in XAML on my axis.
question about FastColumnRenderableSeries:
assuming the UseUniformWidth is set to True (all columns are same width) and Series already displayed: how I could get the actual width for one (any) column from code?
I.e. I do not want to use GetColumnWidth(IPointSeries points, IRenderPassData renderPassData) to computes the width of the columns to be drawn.
Just need to get the actual width for column already drawn.
I’m not entirely sure I’m approaching this the right way, but we’re having an issue with two different but similar situations. The first is drawing lines on the chart, which create regions on the chart, and the second is to connect two different points together with a line.
In both scenarios we need to draw quite a few lines on the chart surface, the problem is that the line series does not draw lines separate from each other, just one line connected, for example, if i need to draw to parallel lines:
——————— Line 1
——————— Line 2
Like that, the series will connect them and make a Z line instead.
The problem is that if we need to draw 5 lines to connect a 1000 points together, we need to add 500 fast line series to the chart surface and that slows down the performance significantly.
Is there a property somewhere that we missed? Or a series that we can use that does not connect all the lines together ?
Thanks in advance!
When I used scichart real-time graph for 3 days(no stop), It does not draw smoothly.
It looks broken… draw, wait for 1 second, draw, wait…..(repeat)
but first day, It worked well..
Why is it??
I use buffer size(1843200) and draw 80 fast lines.
and Memory in my PC is 16GB.
Please help me to solve this problem….
Let me explain the structure of attached views. Default view state is https://imgur.com/a/zqAqpXp .
<VerticalViewPager> <FirstPagedFragment> <TradingViewFragment> <WebView /> </TradingViewFragment> <SciChartFragment> <com.scichart.charting.visuals.SciChartSurface /> </SciChartFragment> </FirstPagedFragment> <SecondPagedFragment> ... </ SecondPagedFragment> </VerticalViewPager>
When FirstPagedFragment is dragged, SecondPagedFragment becomes displayed. You can see it on https://imgur.com/a/2VqZ1HY
The problem is the chart becomes disappeared when ViewPager is on changing state. Here is another link : https://imgur.com/a/xDO6Xtx
It is happened on [Samsung Galaxy S9, API 26] and [Xiaomi Mi A1, API 25] and I did not update displayMetric of chart.
Is there any configuration to fix this issue? Thanks.
All images are attached.
I hope you can help me, please. Is it possible to remove the lines that protrude on the edge of the graphics, as shown in the image? If so, what would be the procedure?
Thank you very much in advance…
Is it possible to give an arrow type style to the axes? As seen in the attached image.
It would be perfect!
Otherwise, I would like to know if it is not possible, not to take into account this characteristic in my development.
I hope you can give me a clue please. Thanks in advance.
Originally my chart would
– create the surface
– setup the chart modifiers
– setup the axis
– add the data (SCIFastLineRenderableSeries).
However, it appears that when you .add(new SCIFastLineRenderableSeries) it recreates all the tooltips on each add, and finally on the very last SCIFastLineRenderableSeries that is inserted will get two duplicate tooltips. This happens both with the default tooltips or custom tooltips.
I finally noticed that some of your examples you setup the modifiers at the end after adding the data. So I moved all the chart modifiers into a separate function and called it after the data is setup, and now the proper number of tooltips appears.
This might either need to be noted somewhere prominent in the iOS docs; or even better the order shouldn’t matter.
Please help me on this, as I want to draw/combine multiple charts on a single surface and I am getting Json values from Api & also attaching the Graph look which I want.
Help me how I can achieve this.
Thanks in advance.
