Using the githuburl in the Threadsubject is not a good idea i think ;-)
Away from that. Nice. Thank you for sharing ;-)

GMan · Apr 9, 2023

Where can i get the missing jars ?

B4X:

#AdditionalJar: fontbox-2.0.27
#AdditionalJar: graphics2d-0.42
#AdditionalJar: pdfbox-2.0.27
#AdditionalJar: VectorGraphics2D-0.13

They are included in the zip in post #1.

Not in my download ?!
But i can download them seperatly

GMan · Apr 10, 2023

Got it - request is requesting ;-)

I dont want to confuse it with the (XUI) XChart lib by @klaus

Open for any suggestion(s) to rename the thread.

Here is the PieChart and DonutChart making use of B4J, B4J Java Object, and inline Java Code.
Copy the attached JAR to your B4J additional library folder

Note that the piechart and donutchart differ by a single line of code only:

For donut chart:

B4X:

........PieSeriesRenderStyle_Donut

For pie chart:

B4X:

.......PieSeriesRenderStyle_Pie

Changing

B4X:

xxxxchart.LabelsDistance = 1.7

...and

B4X:

xxxxchart.PlotContentSize = 0.4

...yields this

This is where I will leave Pie Chart and Donut Chart. A mixture of B4J, JavaObject, and inline Java code. Copy the attached JAR to your B4J additional library folder.

It will "raise events" (actually call Subs) in the Main module of the project when:
1. Entering a chart
2. Exiting a chart
3. Mouse Pressed
4. Mouse Released

It will log the name and value of the series when clicking on a donut/pie slice - you see something like this in the B4J logs:

This is a "wrap" for the LineChart of this Github Project. Basically you only need a timer to change between a static and dynamic line chart. Attached a sample of a dynamic chart and a sample of the static chart.

Use the same JAR as in post #9 of this thread (have attached it again - copy it to your B4J additional Libs folder).

All done by using JavaObject - have added as many "methods" as possible to make it useable.

Dynamic Line Chart:

Static Line Chart:

B4J Code for Dynamic Chart:

Hey Johan, very great library, thanks for this contribution, I do have a question, I started playing around with your library yesterday and although it works as I expected, I seem to not be able to resize the size of the chart, I have tried setting the chart to cover the entire area of my form which is around 1080 width x 800 height, but for some reason it doesn't resize to that size, it stays at around 350 x 350, I looked at the code in the inline java but wasn't able to spot anything that might give me a hint as to why that is happening, are you able to create a line chart of any size?

Please let me know, thanks.
Walter

Change this line in the B4J code for left, top, width, height. Please let me know if that is sorting out the problem.

I already tried that, but the size doesn't change, the chart size remains the same.

I am using a B4XPages by the way, not sure if that makes a differnce.

Which one of the charts are you working with Walter?

Johan Schoeman · Sep 28, 2023

Johan Schoeman said:
XYChartBuilder.RunMethodJO("width", Array(630)).RunMethodJO("height", Array(500)).RunMethodJO("title", Array("Line Chart - Dynamic")).RunMethodJO("build", Null)

And when you change this line in LineChart?
