Hi, does anyone know if there is any chart component(bar chart, pie chart...) based on CLDC application in BlackBerry market?
or how do you develope your chart component(bar chart, pie chart...) based on CLDC application. would you mind giving me your solution?
I know J2ME ChartComponent (http://www.beanizer.org/site/index.p...-ver-1.5.html), but it is based on MIDP, can I use in CLDC application?
Thanks.

if you don't mind using wireless bandwidth you can always do something easy such as Google Charts API.. Send a URL via a GET HTTP request and it returns the chart image: Developerxxx39;s Guide - Google Chart API - Google Code

        fieldWidth = Graphics.getScreenWidth();
