SciChart® the market leader in Fast WPF Charts, WPF 3D Charts, iOS Chart, Android Chart and JavaScript Chart Components
SciChart Android ships with ~90Â Android Chart Examples which you can browse, play with, view the source-code and even export each SciChart Android Chart Example to a stand-alone Android Studio project. All of this is possible with the new and improved SciChart Android Examples Suite, which ships as part of our Android Charts SDK.
Demonstrates how to add Error Bars to an Android Line or Scatter Chart. There are two Error Bar Series types in SciChart Android:
– FastErrorBarsRenderableSeries which can render HlDataSeries or OhlcDataSeries
– FastFixedErrorBarsRenderableSeries which can be used to render an XyDataSeries (which contains one X-point and one Y-point), XyyDataSeries (renders Y values), XyzDataSeries, HlDataSeries and OhlcDataSeries(renders Close values). Error values are fixed and specified by calling setErrorLow() and setErrorHigh() methods.
Tip!
Do you need to change the width of a error bar? Try calling the setDataPointWidth() method passing in any number from 0.0 to 1.0. This alters how much space the bar takes up.
The full source code for the Android Central X Axis and Y Axis example is included below (Scroll down!).
Did you know you can also view the source code from one of the following sources as well?
