Hi,
I set up my xAxis (DateAxis) with a minimalZoomConstrain = DateInterval.fromMinutes(3.0). And here is my PinchZoomModifier:
val pinchZoomModifier = PinchZoomModifier().apply {
direction = Direction2D.XDirection
receiveHandledEvents = true
}
The chart works great and restricts the zoom to three minutes, but I get this error to the console whenever I zoom in to reach the minimalZoomConstrain:
E/Axis: VisibleRange was restored to its last valid value. The range class com.scichart.data.model.DateRange (Min = Tue Jan 09 01:52:40 GMT+01:00 2020, Max = Tue Jan 09 01:55:40 GMT+01:00 2020) either is not valid or it doesn't satisfy MinimalZoomConstrain or MaximumZoomConstrain. To provide fallback value please override AxisCore#coerceVisibleRange(IRange) method
How can I get rid of this error? Is there a way to tell the PinchZoomModifier that there is a min limit?

Hi,
Can you please tell me do you have tool like https://www.scichart.com/documentation/win/current/webframe.html#Fibonacci%20Retracement%20Drawing%20Tool.html
on Android?
If not, please give me a sample code on how to implement this with scichart.
Thanks in advance.

I set a rolloverModifier to a CandlestickSeries, but I can not find a API to hide RolloverMarker,I only find a article about WPF(https://www.scichart.com/documentation/v5.x/webframe.html#RolloverModifier.html)， how could I hide RolloverMarker or change the style of RolloverMarker in Android?

// add to view
this.addView(surface);

I’m using a CategoryDateAxis and seeing the following crash many times in production. The issue is that SciChart is not synchronizing access to SimpleDateFormat, and this will lead to a crash.
Please see following thread for more details on how to fix this issue:

Hi,
I have issue with export SciChart to Bitamp. I have to generate pdf report from data. Report contains two charts.
It is possible to render chart in memory and export to bitmap? I know it is possible in WPF but I couldn’t achive this in Android.
Now my solution is that I render this charts on fragments and wait 1s on each to render and then save chart. But this solution is not good. For slower devices chart is not exported correctly.
For example on one device have strange grid (only exported bitmap, fragment with this chart looks good):

Hi, I want to draw a chart like the attached image.
This is a chart with XyDataSeries, it show as vertical line at each data point and verticle line is a dotted line in order to separated from other series.
Since the OHLC chart will have the open, close on the data point and an impulse chart is forced to draw from an axis, is there any better way that can achieve a series like this? Thank you!

When using GLTextureView on Android 4.4 API 19, there are a few issues. The same issue does not occur on API 27. Have not tested other API levels. If you do not use GLTextureView, this issue doesn’t happen (but due to theming bugs I have to use GLTextureView and not the other 2 types of render surfaces).
-
If activity A has a SciChartSurface and activity B has a SciChartSurface and appears above activity A, then the surface in A dissapears (Shows blank) when you return to it. 100% repro for me. Let me know if you need more info.
-
Due to 1? If you try to re-render the chart on activity A, it will lead to an ANR (app freezes indefinitely) after a few times (see below)
-
Even if you don’t have activity B and only activity A, if you interact with it a few times and show/hide it, it will lead to an ANR (app freezes indefinitely) as well (see below):
ANR log (it freezes the app until you kill it):

I am using the examples app for Android and I am noticing that sometimes in the Line Chart example the background colour changes to black instead of the standard grey colour. Seems to be a random occurrence. I am currently testing on a Nexus 7 running 4.4.2. The problem doesn’t occur on my Nexus 4 running 5.1.1.

Hello,
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

This issue repros on Android 4.4 API 19, but not API 27. It happens with the example project (Multi-Pane Stock Charts). The issue is that on certain zoom levels, the x-axis labels are cut off (so instead of displaying 11 Mar, it just displays 11).
I have tried to override TradeChartAxisLabelFormatter with my custom implementation but saw the same issue, so the bug seems to be in the provider or somewhere else.

Hi all,
Why the API’s for iOS, Android and WPF are not identically?
I have seen many samples on the forum, but to adapt it to a different platform is very hard.
A lot of classes are different for each platform.
- Is there any “comparison” for the different platforms?
- Is this planned to unify the API’s?

In Xamarin.IOS when you set the legend to Horizontal and Top it will create a legend at the top then allow you to scroll horizontally to see all your LineSeries. In Xamarin.Android when you have more Series than can originally fit on the screen, the legend malfunctions and takes up the entire screen. Picture will be attached.

Hi,
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.

I have a line chart and need to implement textAlign: left property for tickLabel on yAxis. I have found some way to do it on the forum, but it does not work in my case:
xAxis.setAxisTickLabelStyle(new AxisTickLabelStyle(Gravity.CENTER, Layout.Alignment.ALIGN_CENTER, 5, 0, 5, 0));
I get the error:
Alignment cannot be converted to int
But according documentation https://www.scichart.com/documentation/android/current/SciChart.Charting~com.scichart.charting.visuals.axes.AxisTickLabelStyle~_ctor.html AxisTickLabelStyle class get 5 int arguments. Can you help me please how to solve it!

I was wondering about the possibilities to show markers. I dug a while in the examples and played with default interactions, which use dragging to update the position of the marker.
On mobile devices this conflicts a little with the pan interaction to move the chart. I saw there’s also the possibility to pan using the axes area. There’s also the possibility to just tap on the chart, which doesn’t conflict with other interactions, to show a marker, but I couldn’t find how to do this. At least there doesn’t seem to be built in support for it? How should this be done?
Additionally I would like once a marker appears to either be able to update only by tapping again at other place on the chart (simple solution) or temporarily disabling the panning such that this gesture only moves the marker and not the chart (preferred, but probably less simple solution). So tapping on the chart would enter “marker mode” which disables zooming and panning and some other gesture – e.g. using an external button on the chart, would leave “marker mode” and enter zoom/pan mode again.
Any ideas how to achieve this? Thanks in advance!
P.S. I’m also using a real time chart, though this probably doesn’t make a difference concerning this.

I want to make my labels positions in the centre of axis (y axis which is transparent). Only three labels have to be showed. On the same height with the min, max and actual points. How can I achieve this.

Hi
I have a line chart that has already been drawn and synced with a sound.
when we play sound, chart begin to scroll horizontally.
but problem is lagging when scrolling chart.
Is there a way to fix this problem?
