android 或 SciChart 的 AnyChart 是否支持不升 x 轴？

Question

I need to build an app that draws a line graph from data that is sent to the phone over bluetooth in real time. Data that I get should draw a graph similar to this . I tried with MPandroid charts but it's not working because is not supported I checked and GraphView doesn't support unsorted x-axis line graphs either. Does anybody know if SciChart or AnyCharts support?

Answer 1

Yes absolutely Scichart supports data not ascending in X.

If you append data to a SciChart Android DataSeries you will see the following warning:

java.lang.UnsupportedOperationException: Data has been changed to a DataSeries which is unsorted in the X-Direction. Unsorted data can have severe performance implications in SciChart.

This warning is intended to prevent you from accidentally appending data to a series that is unsorted (which results in poorer performance). If you intended to do this, then simply set DataSeries.setAcceptsUnsortedData(true) . Now append away!

There are several axis types in SciChart. In MPAndroidChart you only get a category axis (data is measured in X based on x-index). In SciChart you can get a category axis or a value axis (which measures data based on X-value).

To read more about the different axis types in SciChart, please see this article: Axis Types in SciChart Android

Answer 2

Yes, the AnyChart Android library supports unsorted xScale and real-time update of the chart. If you need any sample based on AnyChart, please, contact us support@anychart.com
