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 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…

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.

How to scale axes with different scale factor using pinch zoom?
For example, scale x axis only or scale x axis greater then y axis.

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.

Thank you,

Andrew
