A simple example

package org.matheclipse.core.examples;

import org.matheclipse.core.basic.Config;
import org.matheclipse.core.eval.ExprEvaluator;
import org.matheclipse.core.graphics.Show2SVG;
import org.matheclipse.core.interfaces.IAST;
import org.matheclipse.core.interfaces.IExpr;
import org.matheclipse.parser.client.SyntaxError;
import org.matheclipse.parser.client.math.MathException;

public class PlotExample {
    public static void main(String[] args) {
        try {
            // don't distinguish between lower- and uppercase identifiers
            Config.PARSER_USE_LOWERCASE_SYMBOLS = true;
            ExprEvaluator util = new ExprEvaluator(false, 100);

            // plot a simple function
            IExpr result = util.evaluate("Plot(sin(x),{x,-10,10})");

            if (result.isAST()) {
                StringBuilder svgData = new StringBuilder();
                Show2SVG.toSVG((IAST) result, svgData);
                System.out.println(svgData.toString());
            }
        } catch (SyntaxError e) {
            // catch Symja parser errors here
            System.out.println(e.getMessage());
        } catch (MathException me) {
            // catch Symja math errors here
            System.out.println(me.getMessage());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
