In the picture below you can see that upday bar can be:
1. open in the left
2. close in the right
3. close is greater then open

As you can see in the screenshot I have different behavior

I have this strict mode configuration:

StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()
            .detectDiskReads()
            .detectDiskWrites()
            .detectNetwork()
            .penaltyLog()
            .build());

StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder()
            .detectLeakedSqlLiteObjects()
            .detectLeakedClosableObjects()
            .penaltyLog()
            .penaltyDeath()
            .build());

I have an error when I rotate screen:

hello, I am Japanese

I am sorry that I am not good at English.

I would like to draw a basic real-time chart

Get numbers from arduino
/arduino/analog/0

I’d like to use HttpURLConnection and get numbers as short as possible

There was something I wanted in the sample. I want to rewrite this and use it

AnimatingLineChart

I do not know where to rewrite
I am satisfied if it can be displayed with 1 line chart

I want a format that can be built

Thank you

I have a candlestick chart to display an Ohlc data. (Kotlin, Android)

        val candlestickXAxist = sciChartBuilder
            .newCategoryDateAxis()
            .withVisibleRange(range)
            .withAutoTicks(true)
            .build()

        val candlestickYAxist = sciChartBuilder
            .newNumericAxis()
            .build()

        val fastCandlestickRenderableSeries = sciChartBuilder.newCandlestickSeries()
            .withStrokeUp(upColor)
            .withFillUpColor(upColor)
            .withStrokeDown(downColor)
            .withFillDownColor(downColor)
            .withDataSeries(ohlcDataSeries)
            .build()

        UpdateSuspender.using(priceChart) {
            Collections.addAll(priceChart.xAxes, candlestickXAxist)
            Collections.addAll(priceChart.yAxes, candlestickYAxist)
            Collections.addAll(priceChart.annotations, this.currentAnnotation)
            Collections.addAll(priceChart.renderableSeries, this.fastCandlestickRenderableSeries)
            Collections.addAll(priceChart.chartModifiers, sciChartBuilder.newModifierGroupWithDefaultModifiers().build())
        }

In some cases, I need the chart displays the data in a specific date (X value) instead of user should move/pan the chart.

I have tried this

UpdateSuspender.using(priceChart){
                val lastData = priceSeries.last()
                val lastTime = lastData.timePeriodStart.time
                val oneHourAgo = lastTime - 1000*60*60

                Log.i("CHAR_DEMO", "Display time from ${Date(oneHourAgo)} to ${Date(lastTime)}")

                candlestickXAxist.visibleRange = DoubleRange(lastTime.toDouble(), oneHourAgo.toDouble())
                candlestickXAxist.invalidateElement()
            }

But it didn’t work.

And notice that, I’m not sure why the chart xAxis is CategoryDateAxis but the visibleRange is IRange instead of DateRange.

Can someone help me?

Thank you.

Hello,
in SciChart Android the vertically-oriented axis title is displayed like this:

I’d like to rotate the title -180 degrees, so that it looks like that (that is the default behaviour in SciChart iOS):

Is there a way to achieve that?

Hi all,

I’m developing an app which receives and displays 100’s of samples per second similar to what you would see with the FIFO tutorial. Instead of the sample number, 1000, 1001, etc., I’d like to show seconds so far instead of the sample number.

For example, at sample 1000 display 10, from 1001 to 1099 display nothing, at 1100 display 11, etc. Something simple like sampleNum/100. Can you give me a hint where to start looking to change the behavior of the (major?) tick markings? Do I do something with the NumericAxis class?

Thank you for pointers.

Hi

Please can you give me a guide as to how to pull out the Android EEG channel example into a standalone project so that I can use it and build on it.

I have tried but I am getting errors.

Thanks

I have an error after update Android Stutio to version 3.1
But project is steel builds and run successfully

How can I append a float array to an XYDataSeries?

I’m developing an app with scichart. I receive buffers of 20 floats in a float[] type. How can I append this buffer to an XYDataSeries? The chart is updated in real time each time one Buffer is received with FIFO capacity.

What I need is something similar to:

void updateChart(final float[] a, final float[] b) {
    UpdateSuspender.using(surface, new Runnable() {
            @Override
            public void run() {
                // Append the new data received
                lineData.append(a,b);
                // Zoom series to fit the viewport to the x variable
                surface.zoomExtentsX();
            }
        });
}

Is this possible?
Thank you in advance

I have CategoryDateAxis and whant to setup range limit from series size – 50 to series size + 10

mBottomAxis.setVisibleRangeLimit(new DoubleRange(series.size() - 50d, series.size() + 10d));
mBottomAxis.setVisibleRangeLimitMode(RangeClipMode.MinMax);

And this code works but not as I expected
When I scrol chalt and hits the range limit scroll is stopped BUT chart is zooming in

How to disable zooming when I hits the limit?

Can you help me please!
I was searching forum and see all different questions with dfferent ansvers but no one help for me.

I’m using CategoryDateAxis and whant to show to users vertical lines between days, weeks or month
Its depends from timestamp and visible period.
I need to opportunity to provide themself when to display vertical line.

In chart I display CandlestickSeries from stosk market and users whant to know when one day is ended and new day is begin.

How can I do that?

Hi,
I want to implement a chart that represent currency changed rate, so that the chart will show a rise with a green point and a fall with a red point.

in the image I’ve uploaded I’ve used Custom PaletteProvider to manipulate the colors accordingly.

what I want to implement is instead of coloring the Point (Ellipse) I want to load an Image.
the closest i’ve got is to load a single image to all the points, without theme changing (red or green) accordingly.

I did managed to implement that exact behavior in iOS.

how could I implement a dynamically changing Sprits in a PaletteProvider ?

Thanks in advance…

When I open activity with chart on real devices chart area for a moment has black color and theh succesfuly displayed chart data.
On emulators I do not see thes behavior.
How can I fix black screen?

Hi,

I’m working on the iOS and android version. I’m trying to implemented an animated visible range change on Y axis when zooming/panning X axis.

On iOS, I just have to do:
yAxis.autoRange = .always
yAxis.animateVisibleRangeChanges = true
yAxis.animatedChangeDuration = 0.5

But I can’t find a way to do that on Android, is it hidden somewhere else?

Kind Regards,
Alexis

How to achieve this effect？

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.

our app is about Futures. we will buy license for IOS and Android.

we found some question.

so we need show very small values, like Euro exchange’s values will be from 1.1981 to 1.2008.
its Tick Size is 0.0001 .

but we use LogarithmicNumericAxis with OhlcDataSeries<Date, Double> , surface still linear scale.

other question.
how to custom LogarithmicNumericAxis’s “TextFormatting” like “$0.0000”

Greeting, I want to do a custom cursor, something just like the image, but with candles (a candlestick chart) , and I wanna see all the info (Date, open, close, high, low). Is there any example of it?

Greetings, I wonder if is it any way to save the annotations that I do in the charts?
Because when I leave the chart the annotations gone.

Hi,
I downloaded your Android Examples project to evaluate whether it’ll be a good fit for real time updates.
Replaced SetRunTimeLicenseKey call with my trial keys.
Designer time window displays Sorry!you have not set a LicenseKey message.
RunTime displays your trial license expired.

Any help on this would be great.

Thanks

ECG monitor example

Thank you for your previous response however I would like to know how to recover the Date value from the AxisInfo parameter of the updateInternal method of the AxisToolTip class when used with a DateAxis.

To give context to the question. I am using a DateAxis for the xAxis on this chart and specifying a customised AxisInfoProvider as in the ‘CustomizationRolloverModifierTooltips’ example. When the RolloverModifier highlights some points and if ShowAxisLabels is true then the customised version of the updateInternal method of a customised AxisToolTip is called to to display the xAxis value on the axis.

The AxisInfo object contains a dataValue member variable the question then is: how to convert this back to a Date object.

In my implementation I have the xAxis using a DateAxis in the dataset I am using there is only one data point.

The RolloverModifier is very sensitive it is very hard to highlight that one point.

RolloverModifier rolloverModifier = new VitalChartRolloverModifier();
rolloverModifier.setSourceMode(SourceMode.AllVisibleSeries);
rolloverModifier.setDrawVerticalLine(true);
rolloverModifier.setShowTooltip(true);
rolloverModifier.setShowAxisLabels(false);
rolloverModifier.setIsEnabled(true);
rolloverModifier.setUseInterpolation(false);

Is there a way of making it less sensitive?

can you please provide me source code (XML as well as Java) for the medical app. I have seen ECG example code but it is only for ECG. I want to show all parameters diplayed in pic.

Hi All
By default legends are being draw on scichart surface. I want to draw them outside the scichart surface because as the number of render-able series increase legends hides them. Please give me suggestion how do i do it ?

How to reduce size of colored rectangle of the legends ?

Hi,

I am using Sci chart library to plot the heart rate monitor graph.
I followed tutorials till 06 Tutorial and am able to draw graph with static data.
But as for plotting HRM graph I need, x axix to display current date and time and y-axix displaying BPM.

I tried to use ==>
final IAxis xAxis = sciChartBuilder.newDateAxis()
in my application , but when am executing it getting crashed.

Would anyone help how can I achieve this . Any help will be greatly appreciated.

Thanks,

Hi,

I’m evaluating SciChart for use in a production app.

Is there any way to log exceptions generated by SciChart? Currently I’m logging all handled and unhandled exceptions in my app to my server so that issues can be flagged without users having to manually submit support tickets. SciChart is printing internal exceptions to console – is there any way to override that with our own error handling mechanism? If not, how should we monitor for production errors generated internally by SciChart?

Thanks

I’m initializing my chart as follows:

SciChartBuilder.init(context)
builder = SciChartBuilder.instance()

...

val xAxis = builder.newCategoryDateAxis()
                            .withGrowBy(0.0, 0.05)
                            .withAxisAlignment(AxisAlignment.Bottom)

                            .withScientificNotation(ScientificNotation.LogarithmicBase)
                            .withLogarithmicBase(2.0)
                            .build()
val seriesData = builder.newXyDataSeries(Date::class.java, Double::class.javaObjectType)
                            .withSeriesName("Series A")
                            .build()
seriesData.append(data.dateData, data.yData)
series = builder.newLineSeries()
                            .withDataSeries(seriesData)
                            .build()

UpdateSuspender.using(surface) {
                Collections.addAll(surface.xAxes, xAxis)
                Collections.addAll(surface.yAxes, yAxis)
                Collections.addAll(surface.renderableSeries, series)
}

data object has about 300 valid data points.

Any ideas what’s going on? I tried running this on a new activity. If I swap LogarithmicNumericAxis for a NumericAxis, everything works fine. I looked at the decompiled .class file where the crash was occurring (I don’t have the source for SciChart), and it seems like the crash occurs when major ticks fail to get generated (majorTicks.size == 0). I tried disabling all minor/major ticks but no joy.

for(int var22 = majorTicks.size(); var22 >= 0; --var22) {
            double var23 = var4.fromExponent(var11);
            double var25 = var22 < majorTicks.size() ? majorTicks.get(var22) : majorTicks.get(var22 - 1) * var23;

If you change the logarithmic Y axis to a regular NumericalAxis, the mountain series displays properly (with fill color).

I see that this can be done on WPF (using ShowLicensingWarnings), but couldn’t find the property on Android. How can the licensing warning be hidden on Android?

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:

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).

1. 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.

2. 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)

3. 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):

Reason: Input dispatching timed out (Waiting because the touched window has not finished processing the input events that were previously delivered to it.)

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.
