I am trying to use SciChart library for my project and find out whether it satisfy all requirements.

I am currently trying to display the ECG signal. Therefore the data is coming in realtime.

I have the following configuration

 final NumericAxis xAxis = mSciChartBuilder
                .newNumericAxis()
                .withAxisTitle("Time (seconds)")
                .withDrawLabels(false)
                .withDrawMajorTicks(false)
                .withDrawMinorTicks(false)
                .withDrawMajorBands(false)
                .withDrawMajorGridLines(false)
                .withDrawMinorGridLines(false)
               // .withVisibleRange(0, 2040)
                .withAutoRangeMode(AutoRange.Always)
                //.withAutoRangeMode(AutoRange.Never)
                .build();
        final NumericAxis yAxis = mSciChartBuilder
                .newNumericAxis()
                .withAxisTitle("Voltage (mV)")
                //    .withGrowBy(0.1d, 0.1d)
                .withDrawLabels(false)
                .withDrawMajorTicks(false)
                .withDrawMinorTicks(false)
                .withDrawMajorBands(false)
                .withDrawMajorGridLines(false)
                .withDrawMinorGridLines(false)
                .withVisibleRange(Short.MIN_VALUE, Short.MAX_VALUE)
                .build();

It works but the X axis a little bit scaled/compress.

Here is the result

enter image description here

I need to make it a bit wider.

How can I do this ?

I have tried to set range manually like that

.withVisibleRange(0, 2040)

However in this case it doesn’t show anything.

I would be grateful for any help.

I have two charts (separate SciChartSurface via SciChartGroup) stacked on top of each other. Each chart has its own X-Axis and both charts’ mouse interaction are linked via MouseGroupId. All fine so far.

I then generate a lineseries ‘series1’ on the first surface, 1000 datapoints, time stamps are 1 minute apart. I also generate a second line series ‘series2′ on the second surface, but this series’ first time timestamp start 2 hours later than the first series.

Expected behavior is that the series2 will be shifted by 2 hours and not start at the same position as series1 but rather extend by 2 hours. That is, however, not the case on my chart.

What is wrong here and is this a potential bug?

I need both XAxes to be perfectly aligned, meaning the cross hair label on each XAxis displays the exact same time stamp. Please note that I customized the LabelProvider to display milliseconds also, but I use the same Label Provider for both charts, so no difference here.

Can someone please chime in what is going on?

Please see attached charts to illustrate what I have been describing (screenshot1 shows intended behavior but on the same chart, I want this behavior to occur on separate panes/charts). Screenshot 2 describes the problem I am having.

Thanks

I have DateAxis as X Axis, so I want to trigger a button to zoom In/Out to a specific time at the latest plotted point (Price).
Example: I have zoom button 30 minutes, 15 minutes, 5 minutes and 2 minutes….

Because we have limited vertical space, I would like to change the position of the x-axis title.
Ideally, to the right of the x-axis values.
Using code behind, this was sort of possible, but we would like to do it using xaml.
Also, the code behind solution had problems when resizing the chart.
Is this possible?
