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.
When i go to zoom on my YAxis while a YAxis VisibleRangeLimit is baing set, the zoom does not work correctly. Once the zooming is finished it will reset back to the range limit. If i remove the range limit, the zooming then works as expected.
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?
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):
I have issue with legend on high resolutions screens. Checkboxes and text is very small and hard to read. I couldn’t find any solution to change text size or provide my own template with text size for legend in Android SciChart.
I want to change legend text size depends on screen like it is in Android by declaring size in dimens.xml.
I do that for Axis labels but I don’t know how do the same for text in legend.
Does anyone know how to achieve this?
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

I need to make it a bit wider.
How can I do this ?
I have tried to set range manually like that
However in this case it doesn’t show anything.
I would be grateful for any help.
Is it possible to display the RollOverModifier tooltip on the real points only ? Say I have points (1 1) and (3 3) in my chart and I don’t wan’t the tooltip to display (1.5 1.5), (2 2), (2.5 2.5) etc. when rolling over… Any idea ?
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.
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 hope you can help me I have managed to change the font color, size, but I do not know how to put the annotation with underlined font, who could give me a clue please. I would like to get something like what is shown in the image I attached. Thanks 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.
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.
I want to display auto format date on xAxis (DateAxis) while zooming but I cannot find SubDayTextFormatting function.Is there any way to display minutes and seconds after init months ?there is no DateTime Axis on Android like on iOS ..Should I change to CategoryDate Axis?
Thanks in advance
I want to change the color of the fill bellow the chart(with blue using line chart,FastMountainRenderableSeries etc) but I have problem with defining the BrushStyle and it wont apply on chart(issue with color define-initPaint).Should I change the function ?or how to change default area color ?
