Current version 6.8
New !
Drawing of horizontal lines at a given Y value.
Two methods :
- AddHorizontalLine(Value)
- RemoveHorizontalLine(Value)
Display of the cursor position for YX_CHARTs only.
The xChart Class does exist as a class and a B4X libary.
It works on all three products: B4A, B4i and B4J.
The xChart.b4xlib and the xChart.xml files are attached.
You need to copy the xChart.b4xlib file to the AdditionlLibraries\B4X folder!
Don’t copy the xChart.xml file to the AdditionalLibraries folder, copy it in another folder for all b4xlib xml files.
Example: AdditionlLibraries\B4XlibXMLFiles
The xChart.xml file is for help purposes and is useful with the B4X Help Viewer or the B4XObjectBrowser.
The xChart.xml was generated with this tool: b4xlib - XML generation
Learning B4XViews and XUI, I wrote this CustomView xChart Class.
The xChart.bas file is located in the B4J and shared, relative link, in B4A and B4i.
The code is exactly the same, one class file, for all three platforms.
It is an evolution of Erels' Android Charts Framwork.
It has automatic scales, linear and logarithmic, automatic text size according to the chart size.
These can also be set manually.
Demo projects for all three platforms.
Tested on PC, Android Samsung S10, Samsung Tab S2, iPhone 8 and iPad.
xChartDemoV6_7.zip One project for each product, the xChart class module in B4J folder with a relative link in the two other products.
B4XPagesxChartDemoV6_7.zip A B4XPages cross platform project using the xChart library, you need to copy the xChart.b4xlib file into your AdditionalLibraries\B4X folder.
B4JLogScaleV6_7.zip B4J project showing the logarithmic scales, it uses also the xChart library.
xChart.b4xlib The xChart B4X library file. You must copy it into your your AdditionalLibraries\B4X folder.
xChart.bas The Class module.
xChart.xml Help file, it is useful with the B4X Help Viewer or the B4XObjectBrowser.
Don’t copy the xChart.xml file to the AdditionalLibraries folder! Look above.
This image is from the B4JLogScale demo project, there is only a B4J project to show logarithmic scale examples.
The principles is the same for the two other platforms.
4 lines with 4 different scales the same lines with the same scale.
Radar type chart
H_BAR chart type H_STACKED_BAR chart type
The horizontal scale can be either on bottom, default, or on top.
The vertical scale values can go from bottom to top, default, or from top to bottom.
YX_CHART with display of the cursor position.
When the curor is on a point, the cross-hair color changes to the curve color and a circle is drawn at the point if no points are drawn.
EDIT: 2021.02.28 Version 6.8
Amended display of 0 values in BAR charts.

YXChartCrossHairColor, color for the cross hair cursor on YXCharts
YXChartCrossHairDeltaY, the horizontal line of the cross hair cursor is shifted topwards by the given value only for YX_CHARTs
this is useful to not cover the horizontal cursor line with the finger
EDIT: 2021.01.19 Version 6.6
