Hi, everyone!
Is there any solution to show charts on iOS apps?
I've a couple of apps working on Android devices that uses @Johan Schoeman 's libraries and a client asked me to do it on iOS.
I've seen some GitHub projects, but my knowledge about doing libraries is almost Null.
Thanks in advance!!!

Sorry, but I need a solution for iOS for RadarCharts... Maybe we'll hire someone to create a lib from one of these GitHub projects and share it for free here!
Thanks a lot!!

One comment:
For me, more than 5 items becomes unusable, in your chart, the first years are almost not visible.
Just my comment.
Anyway, in the xChart Class, you can add as many items as you want, but ??!!

And three questions:

1. What represent the two yellow lines?
Are these the crosshair lines of a cursor?

2. What does the value 960 represent?
And how is it generated?
It seems not in relation with the yellow lines.

3. I see that you have negative values!?

The work is still in progress, the filling method is not yet implemented but in the to do list.
Fine tuning takes time.
I think that I can post a test project tomorrow.

Attached you find three test projects, one for each platform.
The xChart.bas module is included in the B4J project, it is linked to the others by a relative link.
Can you please test the Radar charts?

I have tested a lot, but for sure not every combination.

Screenshot of the current version.



In the Radar chart, also, almost everything is configurable.
- For each item you can define the color the line width and filled or not.
- Set the start angle.
- Draw the spider web type scale lines or not.
- Draw the scale values or not.
- Set the colors for the different texts.
- Clicking on the chart and moving shows the values for the item near the cursor, the red radius, the cursor snaps to the nearest item.

Don't know what the lines are... not appears on my project, this is a sample imagen Johan Schoeman sent me.

It's the value shown when you click on a zone.

Not used on my project, values from 0 to 10 mostly.

Let me play a little bit with it until tomorrow and I'll tell you my impressions!!
Thank you so much for your effort!!!
